Specific surface area: 15 -27 m2/g
Standard: YB/T 115-2004
Good surface activity.
When silicon iron and industrial silicon is produced, the silicon steam out of flue is oxidized, then, collect.
Good dielectric property; low coefficient of thermal expansion; high thermal conductivity.
High brightness, fine grain, good size distribution, large specific surface area, best suspendability, high purity, etc.
Application:
Coating, painting, bonding agent, silicon rubber, precision casting, high-grade ceramic, PGL, insulation pouring for general electric and high voltage components, molding and potting compound for integrated circuit, powder coating,welding electrode layer, resin filler.
