Type B silica gel desiccant 3-5mm catalyst carrier silica gel

Type B silica gel is a translucent particle, it is divided into two types: spherical and bolck. The main component is SiO2·nH2O, insoluble in water and inorganic acid, soluble in hydrofluoric acid and concentrated caustic soda solution. High mechanical strength, good wear resistance. The pore volume is 0.50-0.80ml/g, pore size 50-80Å, specific surface area 450-600㎡/g.

The product is mainly used as air humidity regulator, catalyst and catalyst carrier, bedding material for making scented silica gel and feeding animals, and raw material for fine chemical products such as chromatographic silica gel.
