MilliporeSigma™ Supelco™ Silica, 99.8%

Description

Silica is a naturally occurring material in minerals, flint and in some plants in crystalline phase. Silica commonly used in industries is in synthetic form. Surface area, pore volume, pore size and particle size are independently controllable to some extent. The crystalline silica may be classified based on atmospheric pressure as: a. Quartz: = 1143K b. Tridymite: 1143 - 1743K c. Cristobalite: = 1743, over 1973K it forms amorphous vitreous silica glass.
