The study of thermal behavior of montmorillonite and hydromica brick clays in predicting tunnel kiln firing curve

Thermal behaviour of ceramics obtained from the kaolinitic clays of Terra Alta, Catalonia, Spain

“…The experiment was carried out from room temperature to 1300 °C at a heating rate of 10 °C min −1 , in a static-air atmosphere. The kiln firing curves were obtained from the dilatometric data following the method indicated in Vasić et al [11].…”

“…The colour properties were measured in the raw kaolinitic clays and in the fired samples at different temperatures. Colour was defined by measuring the spectral diffuse reflectance according to the CIE, 1931 XYZ colour space (CIE, Comission Internationale de l'Eclairage), which measures colour spaces and calculates the chromatic parameters [11]. These parameters were measured with a CM-700d Konica-Minolta spectrophotometer over the visible range (400 nm to 700 Hnm wavelength range).…”

“…These then expanded during retention at 1000 °C, and the effect was the most pronounced in BC1 (about 0.3 %) and least in the case of BC3 (0.1 %). The expansion that occurred during the retention is rarely reported in the literature (Cobo-Ceacero et al, 2019;Pontikes et al, 2009;Rekecki et al, 2004;Vasić et al, 2017). The expansion is caused and depended mainly on the content of carbonates in the soils that contain relatively low quantities of clay minerals, since high volume anorthite may occur (Vasić et al, 2017).…”

“…In the interval 600 °C -800 °C, sample BC1 lost 7.36 % of the mass, while in the case of BC2 it was about 0.7 %. After 800 °C, endothermic reactions occur with small peaks at about 884 °C which could be related to the destruction of the illites` structure (Vasić et al, 2017). At the end of the test, all samples showed a small exothermic peak at 904 °C -919 °C without the mass loss, which could be related to the formation of spinels, Fe-diopside, and/or amorphous glassy phase, since the mass loss did not occur in that period (Arsenović et al, 2014;Vasić et al, 2017), after which the endothermic processes continued.…”

Sericin-Montmorillonite Composite Nanoparticles as Drug Delivery System in Human Liver Cancer: Development, Drug Release, Cellular Uptake and Cytotoxicity

“…In TGA measurements, the Ser-Mt composite NPs were warmed up to 800 °C. Mt has high stability up to 800ºC but loses some of its mass at about 400 ºC due to the desorption of intercalated crystalline water molecules [31]. Sericin has a degradation temperature of 120ºC.…”
