Studying clay formulations for porcelain ceramics using simultaneous thermal analysis(STA) techniques

In this study, modem simultaneous thermal analysis instrumentation is employed to obtain valuable thermal response behavior of a three primary component porcelain ceramic formulation containing kaolinite, feldspar, and silica. The silica component consisted of both crystalline quartz and amorphous silica. The thermal analysis data obtained in this study provide information related to the behavior of the raw materials in the mixture during the firing of the formulation to produce the porcelain product. The types of thermal analysis data obtained in this study were differential thermal analysis (DTA), thermogravimetry (TG or TGA), and derivative thermogravimetry (DTG). These data were obtained experimentally in our laboratory using a single computerized simultaneous thermal analysis (STA) instrument.
