Crystalline Silica Quartz and Cristobalite
Crystalline silica is a collective term that can refer to quartz, cristobalite, tridymite, and several other rare silica minerals. The term “crystalline silica” usually refers only to the polymorphs quartz, cristobalite and tridymite. All of the crystalline silica minerals have the same chemical composition, but

The detection of quartz in clay minerals by differential
With the use of standard prepared samples of quartz in talc, the minimum level of detection of quartz by DTA was determined to be 0.5% by weight. If sample preparation and experimental parameters are standardized, DTA provides a definitive technique for detection of quartz in clay minerals.
CERAMIC MATERIALS I
CLAY consists of one or more clay minerals together with, in most cases, some free silica and other impurities. The amount of mineral impurities, organic matter present, and particle size vary with the individual clay’s evolution. The common clay mineral is kaolinite; most clays consist of kaolinite in various degrees of atomic disorder.
