Silica mineral, any of the forms of silicon dioxide (SiO2), including quartz, tridymite, cristobalite, coesite, stishovite, lechatelierite, and chalcedony. Various kinds of silica minerals have been produced synthetically; one is keatite. General considerationsSilica minerals make up approximately 26 percent of ...

In ceramic technology the term 'glass' is contrasted with the crystalline state, it is seen as a "super-cooled liquid". When crystalline materials solidify the molecules have opportunity to orient themselves in the preferred pattern during freezing whereas in a glass ...

Quartz was the mineral upon which the Stone Ages were based. With few exceptions, most early stone tools were fashioned of quartz. Outcrops of quartz that were suitable for tool manufacturing were targeted by some of the earliest known mining ...

A widely distributed mineral on the Earth's surface, quartz is a crucial constituent of igneous, metamorphic, and sedimentary rocks. It is formed in igneous rocks as magma cools and silicon dioxide crystallises. Quartz is highly resistant to chemical and mechanical ...
