“…It should be mentioned that the phlogopite remains at 800°C, but it disappears at 900°C and at this temperature appears two more new phases as discussed in the XRD section, because the calcination at a temperature higher than 800°C favors the crystallization of Ca-Al silicate minerals such as gehlenite and anorthite [54]. The anorthite was characterized by three bands at 980 cm -1 , 1075 cm -1 and 1135 cm -1 assigned to asymmetric stretching vibrations of both SiO 4 and AlO 4 tetrahedra [55,56].The gehlenite was characterized by the bands which confirm the structure at 907 cm -1 and 1056 cm -1 and the bands at 925 cm -1 and 850 cm -1 related to the asymmetric stretching of (Si, Al)(O 3 ) and Al-O-Al, respectively [54].…”

Phosphate washing waste (PWW) is one of the wastes generated by the phosphate mine with a very high amount. This waste was investigated in this work to study the effect of the calcination of the PWW at four different temperatures 600°C, 700°C, 800°C and 900°C on its mineralogical and chemical composition. The samples were investigated by X-ray powder diffraction, Fourier transform infrared, differential scanning calorimetry and thermogravimetric analysis, solidstate magic angle spinning nuclear magnetic resonance of 29 Si, 27 Al and 31 P and scanning electron microscope. The results show that the PWW presents a complex system and it suffers a significant change on its mineralogical and chemical composition after calcination. It reveals the presence of carbonate, natural zeolite, fluorapatite, quartz and clay. After calcination, the waste shows the disappearance of some of these phases and the appearance of others and some other phases remain steady.

“…The chemical composition of the ClMx indicates that the raw clay material used for the ceramic production consists mainly of Al 2 O 3 (~16 wt.%) and SiO 2 (~57 wt.%) and minor CaO, K 2 O and TiO 2 (Table 1). The high SiO 2 and low Al 2 O 3 contents might be associated with increased amounts of the clay minerals, quartz and feldspars (Kramar et al , 2012; Boussen et al , 2016; Milošević et al , 2016; Daghmehchi et al , 2018). The molar ratio of SiO 2 :Al 2 O 3 (3.41%) reflects the large contribution of quartz in the sample (Abdelmalek et al , 2017; Milošević et al , 2017, 2019a).…”

“…The K 2 O (1.01 wt.%) is associated with the presence of minor K-feldspar or mica (illite or muscovite) (Monterio & Vieira, 2004; Celik, 2010), while the MgO (0.76 wt.%) is attributed to minor smectite or chlorite (Montana et al , 2011). The slightly larger amount of Fe 2 O 3 (~5 wt.%) may be derived from the hydroxides/oxides in the raw material and may produce red-coloured ceramics (Abajo, 2000; Murray, 2007; Daghmehchi et al , 2018; Milošević et al , 2019a), which is still acceptable in ceramics (Baccour et al , 2008) as a ‘dark-firing’ ceramic body (Dondi et al , 2001; Milošević & Logar, 2017). The relatively large loss on ignition (LOI; 15.86%) may be related to dehydroxylation of hydrated minerals or hydroxides, oxidation of organic materials and decomposition of carbonates (Milheiro et al , 2005; Baccour et al , 2008; Abdelmalek et al , 2017).…”

The production of pottery in the traditional manner using local raw materials can provide insights into the provenance of ancient artefacts. This study uses mineralogical analysis to evaluate the raw clays and tempers used for pottery production in Zlakusa (western Serbia). Particle-size distribution, plasticity, X-ray fluorescence spectroscopy, X-ray powder diffraction, scanning electron microscopy/energy-dispersive X-ray spectrometry and differential thermal analysis techniques were applied. The mineral phases identified in the raw clay sample are kaolinite/halloysite, mica/illite, smectite, quartz, paragonite, feldspar, calcite and hematite. The clay body sample is a mixture of raw clay and crushed calcite in a ∼50:50 ratio, which was confirmed using various techniques. We have also considered and investigated the technological potential of the sampled materials, taking into consideration their actual and potential applications. It was confirmed that the clay body may be used in the manufacture of bricks and pottery, but its industrial application is limited by the paste recipe.

“…Calcium can also signify the presence of natural carbonated minerals such as calcium carbonate (CaCO3) in the clay. Moreover, the potassium can also indicate illite clay mineral (Daghmehchi et al 2018). The SiO2/Al2O3 ratio of 2.46 obtained for the sample are within the range for illite (2.7).…”

Analytical Chemistry Methods of Estimating the Original Firing Temperature of Bricks from a 19th Century Convent in the Philippines: Perspective of a Southeast Asian Country | Mga Pamamaraan ng Mapanuring-Kimika sa Pagtantya ng Orihinal na Temperatura ng Pagsunog sa Ladrilyo Mula sa Isang Ika-19 na Siglong Kumbento sa Pilipinas: Pananaw ng Isang Bansa sa Timog-Silangang Asya

Countries in Southeast Asia have a unique and diverse culture due to its varied ethnic groups having different traditions and beliefs. The process of manufacturing building materials such as brick masonry is one aspect where this distinctiveness is manifested. This study provides a general analytical chemistry method that will estimate the original firing temperature of a historical brick material from a convent in Milaor, Camarines Sur, Philippines. Different instrumental techniques were utilized namely the Energy Dispersive X-ray Fluorescence (EDXRF), Fourier Transform Infrared (FTIR) Spectroscopy and Scanning Electron Microscopy with Energy Dispersive X-ray (SEM-EDX). From these techniques, the chemical and mineralogical composition of the brick was reported. The clay mixture used in the production of the brick is known to be non-calcareous and low refractory, that was fired in an oxidizing atmosphere. The brick’s microstructure is classified within the initial vitrification stage based on the features of the mineral transformations. The results of this study point to an estimated firing temperature range of 650°C to 850°C. An emphasis on the importance of chemical analysis in studying cultural heritage materials in the Southeast Asian region is also highlighted on this paper. Ang mga bansa sa Timog-Silangang Asya ay may natatangi at magkakaibang kultura sanhi ng iba’t ibang mga pangkat etniko na may magkakaibang tradisyon at paniniwala. Ang pamamaraan ng paggawa sa mga materyales ng lumang gusali tulad ng ladrilyo ay isang aspeto kung saan naipapamalas ang pagkakaiba-iba nito. Ang pagaaral na ito ay nagbibigay ng isang pangkalahatang pamamaraan ng mapanuring-kimika para tantyahin ang orihinal na temperatura ng paggawa sa lumang ladrilyo mula sa isang kumbento ng Milaor, Camarines Sur, Pilipinas. Iba’t ibang mga instrumento ang ginamit tulad ng Energy Dispersive X-ray Fluorescence (EDXRF), Fourier Transform Infrared (FTIR) Spectroscopy at ang Scanning Electron Microscopy na nakakabit sa Energy Dispersive X-ray (SEM-EDX). Mula sa mga intrumentong ito, ang kemikal at mineral na komposisyon ng ladrilyo ay iniulat. Ang mga pinaghalong luad na ginamit sa paggawa ng ladrilyo ay masaasabing hindi gaanong madami ang bilang ng kalsiyo at mababang refractory, na sinunog sa isang kapaligiran na sagana sa hangin. Ang mga pinaka-maliliit na istruktura ng ladrilyo ay masasabing nasa paunang yugto ng pagtunaw ng mga mineral sa luad, batay sa mga pagbabagong anyo ng mga ito. Sa mga resulta ng pagaaral, masasabi na ang tantyang temperatura ng pagsunog ay nasa 650°C hanggang 850°C. Binibigyan ng diin ang kahalagahan ng pagsusuri ng kimika sa pagaaral ng mga materyales na pamanang kultura sa rehiyon ng Timog-Silangang Asya ay naitala din sa pagaaral na ito.
