The use of silica silica ?? ???? widespread presence of silica nano-silica factory in nature, and other minerals constitute the rock. Naturally occurring silica, also called silica nano-silica quality, is a hard refractory solid. The main ingredient is silica, quartz, clear quartz crystal, the crystal is, we often say. Chemical properties of silica silica chemically inert, does not react with water, nor with acids (except hydrofluoric acid) nano-silica reaction, but it can react with alkali or alkaline oxides to form salts. For example: High 2NaOH + SiO2 === Na2SiO3 + H2O CaO + SiO2 === CaSiO3 quartz minerals on the moon was first discovered in a few classes at the nano-silica crushed granite products, felsite also filled in a lot of cristobalite mineral, its fine structure and composition analysis showed that these quartz cristobalite changes actually made over.
