What is macroporous microsphere silica gel

What is macroporous microsphere silica gel?

Coarse porous silica gel, also called type C silica gel, wide pore silica gel is a kind of silica gel, a highly active adsorption material, an amorphous substance, and its chemical formula is mSiO2 · nH2O. It is insoluble in water and any solvent, nontoxic and tasteless, with stable chemical properties, and does not react with any substance except strong base and hydrofluoric acid. The chemical composition and physical structure of macroporous silica gel determine that it has many characteristics that are difficult to replace by other similar materials: high adsorption performance, good thermal stability, stable chemical properties, high mechanical strength, etc.

The appearance of macroporous silica gel is white, and there are three types of products: blocky, spherical and microspherical. Coarse porous spherical silica gel is mainly used as gas purifying agent, desiccant and acid remover of insulating oil; Coarse porous blocky silica gel is mainly used as catalyst carrier, desiccant, gas and liquid purifying agent, etc.
