Descrizione generale

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.

Applicazioni

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

Caratteristiche e vantaggi

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

Altre note

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

Synthesis of ZnO Aggregates and Their Application in Dye-Sensitized Solar Cells

One of the more traditional photovoltaic devices, single crystalline silicon solar cells were invented more than 50 years ago, currently make up 94% of the market. Single crystalline silicon solar cells operate on the principle of p-n junctions formed by joining p-type and n-type semiconductors.
