ʻO ka silica gel desiccant kahi mea adsorption ikaika loa, ka mea maʻamau i hoʻomākaukau ʻia e ka hoʻopili ʻana i ka sodium silicate me ka sulfuric acid, ka ʻelemakule, ka waiʻawaʻawa a me ke ʻano o nā kaʻina hana ma hope o ka mālama ʻana.ʻO ka silica gel kahi mea amorphous, a ʻo kāna ʻano kemika he mSiO2.nH2O.ʻAʻole hiki ke hoʻoheheʻe ʻia i loko o ka wai a me nā mea hoʻoheheʻe, ʻaʻohe mea ʻawaʻawa a ʻono ʻole, me nā waiwai kemika paʻa, ʻaʻole e hoʻopili me kekahi mea koe wale nō ke kumu ikaika a me ka waika hydrofluoric.ʻO ka hoʻohui kemika a me ke ʻano kino o ka silica gel e hoʻoholo ai he mau hiʻohiʻona i paʻakikī ke hoʻololi i nā mea like ʻē aʻe.Loaʻa i ka silica gel desiccant ka hana adsorption kiʻekiʻe, ke kūpaʻa wela maikaʻi, nā waiwai kemika paʻa, ka ikaika mechanical kiʻekiʻe, etc.
