Product Desciption

Brief Introduction



Product features:

  Silica alumina gel looks light yellow in appearance. chemical formula: mSiO2. NAl2O3. XH2O,
with stable chemical properties, not burning, dissolving in any solvent.

  Compared to narrow pore silica gel, narrow pore silica alumina gel is about the same in low humidity adsorption volume quite (such as RH = 10% RH = 20%), but high humidity adsorption volume (such as RH = 80% RH = 90%), narrow pore silica alumina gel is 6-10%, much higher than narrow pore silica gel, and its thermal stability is also higher than narrow pore silica gel (200 ºC), above 150 ºC, so, silica alumina gel is very suitable for temperature swing adsorption, separating agent.

  Product character:

It is a kind of alumina-containing silica gel, the chemical formula is mSiO2,nAl2O3, xH2O has the
performance of high strength and adsorption, it has better application in the high temperature adsorption
or the separation of various gases. There are two types of alumino silica gel: Type-H is ordinary and
type-W is waterproof ones.
