It is a kind of non-crystalline micro-porous solid powder,its pore diameter is 8-16nm. Its chemical molecular formula is mSiO2.nH2O, insoluble in water or any other solvent (except the caustic alkali and hydrofluoric acid). It does not react with any acid, alkali or salt. It is nontoxic, tasteless, flame-resisting and nonexplosive. It possesses high stability under hot or cold atmosphere and is harmless to human body,mainly used in beer industry.


  1. It has large specific surface area and numerous fine-pored structure.It adsorbs the proteins which cause beer turbid and removes them through filtering, just within several minutes, thus prolonging beer storage period by 180-240 days and keeping beer from being cold muddy.
  2. It does not affect the beer foam or taste.Thanks to its superior physical and chemical properties,it does not have any adverse effect on the beer foam or taste.It generally recognized by the world beer industry.
  3. It helps improve the filter promoting effect.It is chemically stable,contains no beer soluble substances,Its surface area and porous structure are both superior to diatomite.It is a kind of ideal filter promoter in aiding diatomite filter,making beer brighter and clearer.
