Muuqaalka aluminiumjel silicawaa huruud fudud ama cad cad oo leh qaacido kemikaad mSiO2 • nAl2O3.xH2O. Hantida kiimikada deggan. Gubasho la'aan, aan lagu milmi karin dareere kasta marka laga reebo saldhigga xooggan iyo hydrofluoric acid. Marka la barbar dhigo jel silica daloosan, awoodda adsorption ee qoyaan hooseeya waa la mid ah (sida RH = 10%, RH = 20%), laakiin awoodda adsorption ee huurka sare (sida RH = 80%, RH = 90%) waa 6-10% ka sarreeya jel silica daloolin ganaax, iyo xasiloonida kulaylka (350 ℃) waa 150 ℃ ka sarreeya jel silica dalool fiican. Sidaa darteed aad bay ugu habboon tahay in loo isticmaalo sida adsorption heerkulka variable iyo wakiilka kala soocidda.
