- Silica Powder (Si02), Amorphous, Designations:
Chemical Name: Silicon dioxide
Chemical Formula: SiO2
- Silica Powder (Si02), Amorphous, Description:
Silica is noncombustible, colorless or white, tasteless "crystals". It occurs naturally in the amorphous form. The specific gravity and melting point depends on the crystalline form. Silica is known to occur in 17 crystalline phases or modes and five amorphous phases.
- Silica (Si02) Types Available:
a) Aerogel
b) Amorphous
c) Colloidal
d) Diatomaceous
e) Food grade
f) Fumed
g) Fused
h) Hydrophilic
i) Hydrophobic
j) Novaculite
k) Precipitated
l) Quartz
m) Synthetic
n) Traction sand
o) MIL-S-14760 (AR) specification (milspec. cancelled on 4 FEB 03)
p) SAE- AMS3755B (fumed, white & amorphous powder)
- Silica Powder (Si02) Technical Comment:
a) Fused silica is amorphous. It has virtually no crystalline-silica, which is commonly found in sand.
b) Silica sand is crystalline. Crystalline silica is a leading cause of Silicosis.
