Silica Powder, 5.0μm

Catalog NumberACFR000036

CategoryFunctional Inorganic Powder

Description	Silica powder is an inorganic non-metallic material processed from natural quartz, with silicon dioxide (SiO2) as its main component. It is non-toxic, odorless.
Application	Widely used in electronic materials, advanced coatings, engineering plastics, rubber, and precision casting, where high thermal conductivity, low expansion, and enhanced mechanical stability are required.
Al₂O₃	≤1.0%
Fe₂O₃	≤0.3%
Feature	Uniform particle size distribution with high whiteness and hardness. Low oil absorption, excellent suspension properties, and good temperature resistance. Resistant to acid and alkali corrosion, with outstanding dielectric properties. Low coefficient of thermal expansion and high thermal conductivity. Reduces shrinkage during curing, minimizes internal stress in components, and prevents cracking.
Hardness	7
Ignition Loss	≤ 1.0%
Particle Size	5.0±1.0μm
SiO₂	≥97.0%
Volatiles	≤ 0.5%
Whiteness	≥90%
