Descrição geral

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.

Aplicação

Silica was used in synthesis of silicalite. Silica was used to assist the catalytic growth of oxide and nitride nanowires.

Características e benefícios

Has interesting thickening and thixotropic properties, and an enormous external surface area.

Outras notas

Particle sizes are for primary particles, which form branched, chain-like aggregates a few tenths of a micron long.
May contain adsorbed H2O and CO2 which is removable by calcining at >900°C
