일반 설명

Silica is a naturally occurring material in minerals, flint and in some plants in crystalline phase. Silica 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.

애플리케이션

Low density filler for coatings and plastics.
Silica glass spheres are low density filler for coatings and plastics. Silica was used in synthesis of silicalite. Silica was also used to assist the catalytic growth of oxide and nitride nanowires.

특징 및 장점

Light weight, crush-resistant filler. Imparts dimensional stability, reduces warpage, reduces plastic melt viscosity and provides multidirectional orientation in reinforced composites.

물리적 형태

Hollow, spherical non-porous glass beads.

Well crystallized silicalite-1 has been obtained from three sources of amorphous silica, namely, rice hull ashes, commercial Davisil, and a fume silica from Aldrich. The silicas were first dissolved in glycerol according to a recently described reaction. This reaction transforms
