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 base 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 6-10% higher adsorption capacity at high humidity levels (e.g., RH=80%, RH=90%). It also has a thermal stability of over 350ºC, making it suitable for variable temperature adsorption and separation.
Application: Al Silica Gel is primarily used for the adsorption and separation of light hydrocarbons by dehydrating natural gas. It can also serve as a catalyst and catalyst carrier in the petroleum industry, industrial desiccant liquid adsorbent, and for gas separation.

Aluminium Silica Gel Moisture Absorber Beads in 2.0kg or 500kg bags. Blue Silica Gel for effective moisture control.
Blue silica gel is composed of blue or light blue glassy particles. It can change color from blue to purple and finally to light pink as it absorbs moisture, indicating the humidity level of the environment. This product 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 also be used with ordinary silica gel or a drier to assess moisture absorption levels and determine relative humidity. This versatile product is commonly used as a silica gel drier for packing precision instruments, leathers, shoes, clothes, foodstuffs, medicines, and household electric appliances.

Cobalt-free color-changing silica gel beads.
The European Union classified cobalt chloride as a Class II carcinogen in 1998, leading to the ban of blue gum containing cobalt chloride in Europe and the United States. To address market demands, cobalt-free environmental discoloration silica gel was developed.
This product is a non-toxic alternative to blue gum color-changing silica gel. It is made from fine porous silica gel infused with an inorganic salt mixture and new compound dyes, eliminating environmental pollution caused by traditional dyes and discoloration agents. With its original technological conditions and excellent adsorption performance, it represents a new generation of environmentally friendly products.
The cobalt-free environmental discoloration silica gel is primarily used as a desiccant and indicator of desiccant saturation levels in sealed packaging. It is ideal for maintaining the relative humidity of space medium in precision instruments, general packaging, and instruments vulnerable to moisture.

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 for water purification, dry storage of materials and equipment, and high purity gas dehydration and refining.
