THERMAL PARAMETERS OF SOME NATURAL SILICATE AND NON SILICATE ROCK’S MINERALS -

A mineral is a naturally occurring solid with a structure and definite chemical composition. Although similar to rocks, minerals are the building blocks for making rocks, and are found in various types of rock in differing shapes and chemical compositions throughout the Earth's crust. In current paper thermal behavior at room temperature to 1000°C was obtain by thermogravimetry analysis for two silicate minerals such as calcite, whiting and two non silicates such as china clay, Talc. Simulated TGA curves were made for reactions with different kinetic models, including chemical, diffusion and mixed mechanism at different heating rates such as Kinetic parameter like activation energy, entropy, Gibbs energy also find for decomposition stage as function of temperature with help as „Coats Redfern method. This comparative appraisal of the characteristics of the CR approach to kinetic analysis of TGA data is that the CR approach is generally unsuitable for determination of kinetic parameters. The effective thermal conductivity of silicate and non silicate mineral is at 1000°C.
