get priceSilicate minerals are rock-forming minerals made up of silicate groups. They are the largest and most important class of minerals and make up approximately 90 percent of Earth's crust. In mineralogy, silica (silicon dioxide) SiO2 is usually considered a silicate mineral. Silica is found in nature as the mineral quartz, and its polymorphs. On Earth, a wide variety of silicate minerals occur in an even wider range of combinations as a result o

The micromorphology of amorphous silica pseudomorphs suggests that the volume-preserving replacement of non-silicate minerals proceeds via an interface-coupled dissolution precipitation process. We conclude that colloid flow and post-depositional shearing create but also destroy natural photonic crystals.

This synthesis process resulted in the formation of silica by precipitation, an achievement realised only when the precursors used were prepared by heating the starting clay at 600 °C and above. The absence of synthetic products with crude or calcined clay at 500 °C as precursors is due to a somewhat aqueous dissolution of constitutive clay minerals, which are kaolinite and metakaolin.
