Silicon Dioxide for Refined Oil:
This product is a kind of non-crystalline micro-porous white powder. Its main composition is SiO2.n H2O (more than 98%), which is non-toxic, tasteless and stable chemical performance. It will not react with any acid, alkali or salt except caustic alkali and hydrofluoric acid under the normal conditions. It has plenty of tiny pores inside and considerable surface area (Pore Diameter: 8-10nm).
Silicon dioxide for refined oil can be used as dephosphorization, removing saponin and heavy metals.
