“…The increased quartz in beneficiated feldspar shows that the treated material will possess improved hardness, durability, resistance to chemical corrosion, control density, porosity, and shrinkage. The increased minerals will be expected to increase the fluxing potential of the material in ceramic tile production [16,20]. Iron impurity in the feldspar reduced by 52.1241% and its oxide by 58.9265%.…”

Clay, feldspar and silica sand are important industrial minerals which often need treatment commonly known as beneficiation to improve the quality of ceramic tiles produced from these materials. The different minerals, after sorting, were treated separately in distilled water, alcohol and hydrochloric acid before being crushed in a ball mill; they were then characterized using a pelletron accelerator. The results show an increased silicon content for clay, silica sand and feldspar; and reduced aluminum content for clay and silica sand but not for feldspar. Iron impurity and its oxide are also shown to reduce by over 50% in all the minerals while potassium was found to be the dominant element in feldspar among the defining elements. In conclusion, the increased quartz in the mineral will improve the hardness, density, porosity, and rigidity of ceramic tiles as well as providing support and controlling shrinkage. Furthermore, increasing the mineral quotient in feldspar will enhance its fluxing potential.

“…Qualitative identification of the phases present in the clay bricks by XRD patterns is relatively easy, although several factors makes complication for accurate identification of the phases present in them [13]. Phases developed during the firing step of the clay ceramic bodies are generally correlated with their physico-chemical and mechanical properties [14]. On the other hand, mineralogy study of the clay-based ceramic bodies is one of the widely accepted tools for the approximate determination of firing temperatures.…”

Bricks, a prevalent building material, are used extensively in the construction industry. India and the United States, for example, consume 20 billion and 9 billion bricks each year, respectively [1]; [2]. The annual worldwide production of bricks is about 1.391 trillion units and demand for bricks is expected to continue rising [3]. With increasing demands of the construction industry, bricks quality and cost become more important day by day. Clay bricks, made from clays, silica, fluxes, coloring and other raw materials are one of the simplest examples of the traditional ceramic body. They are prepared by grinding, sieving, mixing, moistening, shaped by pressing, casting or other processes, usually at room temperature. Then they are dried and subsequently fired at a high temperature. Bricks are widely used in buildings, foundation walls and boundary. Depending on the degree of firing at high temperature, the chemical/mineralogical, physico-chemical, mechanical and thermal properties of the ceramic bodies are varied. All these properties of the clay ceramic bricks are interrelated to each other. Different clay minerals are the principal raw materials which have a large effect on their technological properties for manufacturing various clay bricks [4]. Content of water and dispersion of the solid phase of the clays used for the production of the clay bricks should be optimized taking into account subsequent drying and sintering to ensure the maximally high parameters of the brick product. The chemical composition of the clay raw materials is one of the main indicators for selection of a component for the final mixture. Al 2 O 3 has the largest effect on the properties of ceramic articles. As the Al 2 O 3 content increases the refractoriness and mechanical strength of the material increases. On the other hand, SiO 2 decreases the shrinkage and it also decreases refractoriness of the ceramic products. Varieties of feldspars, sodium, potassium, calcium, magnesium, iron and titanium oxides are strong fluxes, which decrease the viscosity of the liquid phase of the ceramic products. High Fe 2 O 3 and TiO 2 content of clay reduce the quality of the product but offer higher plasticity and mechanical strength. On the other hand, the amounts of fluxing oxides show a direct correlation with bulk density and an inverse relation with water absorption of the fired clay ceramic bodies. Important source of these fluxing oxides are different feldspars and the presence of high concentration of fluxing components in the clay ceramic body permit a lowering of its firing/sintering temperature [5]; [6]; [7]; [8]. It was investigated the effect of the particle size distribution of feldspar on the formation of pores in the

The work evaluates the effect of firing temperature on the mechanical properties of ceramic tiles. This was with the view to determine the optimum processing condition for Osun State ceramic tiles. Ceramic raw materials collected from Osun State were batched using clay-feldspar-silica sand blending ratio of 5:4:1, 5:3:2, 5:2:3, 5:1:4, 6:3:1, 6:2:2, 6:1:3, 7:2:1, 7:1:2 and 8:1:1 by weight; and homogeneously mixed. Three replica samples were moulded by the method of dry forming, fired at 1200, 1300 and 1400 oC and subjected to breaking and flexural strength tests using the Universal Testing Machine while the hardness test was carried out on a Moh’s scale. The results showed that breaking strength, flexural strength and Moh’s hardness fell within the range 199.43 to 325 N, 11.97 to 19.50 N/mm2 and 2.5 to 4 MH respectively, while Figures revealed that samples with 60% clay, 10% feldspar and 30% silica sand fired at 1320 oC will process the best mechanical properties. In conclusion, ceramic raw materials collected from Osun State are viable for ceramic tile production.
