Type A silica gel is a transparent or translucent particle with a chemical molecular formula mSiO2.nH2O. It is insoluble in water and inorganic acids, soluble in hydrofluoric acid and strong caustic soda solutions. This silica gel exhibits high mechanical strength and good wear resistance.
It is primarily used for drying and moisture-proofing applications. Additionally, it can serve as catalyst carriers, adsorbents, separators, and variable-pressure adsorbents.

Properties:
Al Silica gel is colorless or light yellow transparent or translucent spherical particles with a chemical formula mSiO2.nAl2O3.xH2O. It has stable chemical properties, is non-combustible, and insoluble in any solvent except strong bases and hydrofluoric acid. Compared to silica gel with fine holes, it has similar adsorption capacity at low humidity levels (e.g., RH=10%, RH=20%), but offers 6-10% higher adsorption capacity at high humidity levels (e.g., RH=80%, RH=90%). Additionally, its thermal stability (350ºC) is more than 150ºC higher than silica gel with fine holes, making it ideal for variable temperature adsorption and separation applications.
Application:
Al Silica Gel is primarily used for the adsorption and separation of light hydrocarbons through natural gas dehydration. It can also serve as a catalyst and catalyst carrier in the petroleum industry, as well as an industrial desiccant, liquid adsorbent, and gas separation agent.

Discover our Color-Changing Silica Gel Moistureproof Balls in 2kg or 500kg bags. The blue indicating silica gel offers superior moisture absorption for effective moisture control.
Blue silica gel consists of blue or light blue glassy particles. It can change color from blue to purple to light pink as it absorbs moisture, indicating the humidity level of the environment and the need for replacement. It can be used as a desiccant on its own or in conjunction with Type A Silica Gel.
Blue silica gel is primarily used for absorbing moisture and preventing rust in instruments, gauges, and equipment in enclosed conditions. When it absorbs moisture, it changes color from blue to red, visually indicating the relative humidity of the environment. It can be used with ordinary silica gel or a drier to gauge the moisture absorption level and relative humidity. This versatile product is widely used as a desiccant for precision instruments, leather goods, shoes, clothing, food items, medicines, and household appliances.

Coarse pore microsphere silica gel consists of milky white particles with the main composition of SiO2·nH2O. It is insoluble in water and inorganic acids but soluble in hydrofluoric acid and strong caustic soda solutions. The pore volume ranges from 0.80-1.2 ml/g, pore diameter from 8-12nm, and surface area from 350-460m2/g.
This silica gel is primarily used as a catalyst and catalyst carrier for essential petrochemical products like phthalic anhydride, aniline, maleic anhydride, and triacrylonitrile. It is also utilized in refined petroleum products, selective adsorption separation of organic gases and liquid components, ion exchange to remove harmful elements from water, dry storage of materials, equipment, and high purity gas dehydrating refining.
