“…Therefore, the abovementioned lead free glasses are not applicable to compositions requiring very low processing temperatures in applications such as low firing TFR overglazes and sealing glasses in flat screens. 206,207 Nevertheless, silicate, borosilicate or borophosphate glasses have found large scale low temperature applications such as the overglazing of architectural and automobile glass, 34,46,47 and enamelling of aluminium. 35,47,[54][55][56][57]208 In these applications, the processing window between sufficient melting of the glass and degradation of the substrate is narrow, and firing schedules are tightly controlled, so a very wide stability range against crystallisation is not necessary.…”

The present work critically reviews the scientific and patent literature on low melting bismuth based oxide glass frits in materials for electronics, sensors and related applications such as sealing glasses, solar cells, architectural and automotive glass, the main motivation being to replace lead based materials by environmentally more benign ones. Due to similar glass forming properties of Bi and Pb, Bi based glasses are the closest 'drop-in' alternative for lead bearing formulations, and are therefore actually replacing them in many applications, helped also by previous experience with Bi containing materials in thick film technology and component metallisations. The outstanding issues are discussed, e.g. matching the lowest processing temperatures achieved by the classical lead based glasses without sacrificing durability and stability, as well as stability versus chemical reduction. Finally, consideration is also given to special 'heavy' glasses (often containing Bi and Pb together) that are useful in fields such as optics, superconductors and nuclear technology, as well as to specific Bi 2 O 3 containing crystalline compounds.Keywords: Glasses, Bismuth, Bi 2 O 3 , Electronics, Optics, Thick film technology, Sensors Introduction Low melting glasses in electronics and other applicationsAs for ceramics, inorganic glasses, glass-ceramic and glaze materials have long gone beyond their traditional uses to address a wide array of modern technological challenges, Owing to performance and cost criteria, most standard glasses have relatively high softening points. However, there are many technological applications where a low softening temperature is required, in order to lower energy expenditure, avoid damaging devices in contact with the glass during processing or ensure compatibility with other materials:(i) hermetic sealing of packages, lamps, electrical feedthroughs and semiconductor devices 13,14,16,17,19,44,45 (ii) hermetic sealing and mechanical attachment of sensors 23,27 ( Fig. 1) (iii) encapsulation of semiconductor devices 29,30 (iv) overglazing of automotive, packaging and architectural glass 33,34,[46][47][48] (v) photovoltaic (PV) solar cell technology -conductors and contacts 42,43,[49][50][51][52][53] (vi) enamelling of aluminium in architecture and home appliances 35,[54][55][56][57][58] (vii) thick film (TF) electronics and other devices 21,22,24,25,27,59 (Fig. 1, the section on 'PbO in low melting frits and TF technology'); especially, special low firing compositions for fabrication of circuits and sensors on glass or metals. 1,28,[66][67][68][69][70][71][72] For these applications, glasses are often formulated as frits (e.g. finely divided powder), which may be applied, dispersed in a suitable medium, onto a substrate by various methods such as slip casting, screen printing, roller/curtain coating, spraying, dispensing and electrophoresis, or as preforms for sealing. Classically, the aforementioned applications have to a great extent used lead based glasses, which have a rather unique combinat...

“…The most important compound for imparting a high refractive index to glass is lead oxide, which has been use for this purpose for centuries. The lead glasses have a low softening temperature, good brilliance, and a wide temperature interval of melting [4][5][6][7][8][9][10][11][12]. However, the production and application of lead-bearing glasses in the industry is undesirable due to the toxicity of lead compounds on the human organisms as well as the environmental issues, lead free glasses have became an interesting topic for researchers and they investigate the replacement of lead by other heavy chemical elements such as barium, bismuth, titanium, zinc and zirconium.…”

Many difference useful and decorative articles have been made from glasses over the centuries, especially lead-containing glasses. Due to harmful effects of lead from glass fabrication process on human beings and considering the health as well as the environmental issues, many researchers tried to produce leadless glasses using some heavy chemical elements such as barium, bismuth and zirconium. Nowadays, barium compounds seemed to be satisfactory and to be able to increase the refractive index. For production of high quality crystal glasses with high refractive index in Thailand, most raw materials including high quality sand have been imported. Because, Thailand, in fact, is rich in many kinds of raw materials for glass manufacturing, therefore, this work is set up to study the fabrication of the lead-free high refractive index glasses using local sand and barite as the main raw materials. After complete melting, the physical and optical properties of the prepared glass samples were determined to compare these properties with those of glasses prepared from foreign sand. It was found that the prepared glasses produced from local raw materials were suitably for restoration, decoration, radiation shielding, as well as glass jewelry. These glasses can be considered as one of the environmental friendly materials.

The effect of binders on the quality of paint coatings based on lead-free enamels and meeting the requirements of standard TU RB 100029049.030 is considered. It is established that enamel compositions can be prepared using 20% solution of oxyterpene resin in turpentine and 2% alcoholic solution of Na-carboxymethyl cellulose of grade 7MF. The use of an aqueous solution of dextrin as a binder deteriorates the quality of enamel coatings: it produces color modifications, loss of luster, and formation of crackle.Enamel composites for decorating glass articles are stabilized colloid systems consisting of two main components: a solid-phase filler and a binder. The solid-phase filler in decorating glass articles is represented by a finely dispersed mixture of low-melting glass with colorant agents. The binder, which, as a rule, contains a film-forming agent, a solvent, and a plasticizing agent, envelopes the powdered enamel particles providing strong adhesion of the film to the unfired surface that has to be painted. As a consequence, a continuous solid elastic film is formed. The binders used in the silicate industry include turpentine oil, products of the wood-chemical industry (such as polyterpenes, oxyterpene resin, oxypolymers, colophony), dextrin, water-soluble polymers such as polyvinyl alcohol (PVA), and carboxymethyl cellulose (Na-CMC) [1 -3]. The binding agents used in enamel composites have to decompose, volatilize, and burn during the firing of enamel coatings on glass before the enamel starts melting. Otherwise, reactions between the products of binder decomposition and enamel components, as well as resulting compounds may have a substantial effect on the properties of enamel coatings in firing: modify color, deteriorate their luster and adhesion, increase the firing temperature.The purpose of our study is to investigate the effect of binders on the quality of paint coating based on lead-free enamels and meeting the requirements of TU RB 100029049.030 standard.The solid-phase filler in our study was a finely milled (fraction below 40 mm) lead-free enamel dried for 1 h at the temperature of 100 ± 5°C and containing 95% low-melting glass and 5% chromium oxide pigment. The main components in the synthesis of low-melting glass were oxides of alkali metals, silicon, boron, barium, zinc, titanium, phosphor, and aluminum [4]. The following binders were used: 20% oxyterpene resin solution (TU 81-05-69-69) in turpentine, 2% alkali solution of Na-CMC of grade 7MF and 50% aqueous solution of dextrin. To prepare experimental compositions, the powdered enamel in a jasper mortar was mixed with particular binders in the ratio of 70 : 30. Enamel compositions were applied with a brush on a soda-lime glass substrate and fired in a muffle furnace in an oxidizing gaseous atmosphere at a temperature of 580°C with a 30 min exposure. Fired enamel coatings that had good luster, prescribed color, and no crackle were accepted as the reference standard.The diffraction patterns of samples were recorded using a DRON-3 diffractometer (Cu...
