Characteristics：
Shape: Pellets. Color: cream, translucent. It contains lump and ball types.
Pore volume: 0.8--1.0ml/g, average pore diameter: 8.0--10.0nm, specific surface area: 300--400m2/g, specific heat is 0.92KJ/KG.℃ and thermal conductivity is 0.167KJ/M.HR. ℃.
Use：
Used as the raw material for preparation of silica sand. After being further dried and screened, it forms macro-pored silica gel which is used as drier, adsorbent and catalyst carrier。 At the same time, clear out organic acid and high polymer in insulated oil etc.
