Ethyl silicate (TEOS) bụ mmiri mmiri na-enweghị agba, nke a na-ejikarị eme ihe dị ka ihe mkpuchi na-eguzogide okpomọkụ, ihe mkpuchi na-eguzogide kemịkalụ, ihe njikọ silane, ihe ndị na-eme ka ihe ndị dị ndụ na-emepụta ihe, yana ihe na-ebute ụzọ maka ihe nkiri sio2 nke kemịkalụ (CVD) na mpaghara semiconductor, wdg. Ebe agbaze nke ethyl silicate bụ -77℃, ebe isi ya na-esi bụ 165.5℃. Ọ na-agbaze ntakịrị na mmiri ma na-agbaze na ethanol na ether.
A na-eji ya eme ihe dị ka ihe mkpuchi na ụlọ ọrụ eletrọniki yana dịka ihe nhazi maka iko anya na ihe na-agbakọta ọnụ.
A na-eji ya eme ihe maka ịkpụ ihe dị ka ihe e ji ejikọta ihe e ji ebu ájá; Elu ígwè e ji ethyl silicate kpụọ nwere ike igbochi ire ere na mmiri. Enwere ike iji ethyl silicate mee ka elu ọla ndị ahụ dị na silicon, a na-ejikwa iko anya eme ihe nke ọma nwere ike ime ka ìhè ya dịkwuo elu. Enwere ike iji ntụ silica dị oke mma nke a na-emepụta mgbe hydrolysis zuru oke mepụta phosphors. Ethyl silicate bụ ihe e ji mmanụ silicone mee. Enwere ike iji ethyl silicate mepụta ihe mkpuchi na-eguzogide okpomọkụ na nke na-eguzogide kemịkalụ. Na Japan, a na-eji 90% nke ethyl silicate eme ihe dị ka ihe ndabere maka ihe mkpuchi mgbochi ire ere (agba zinc bara ụba).
A na-ejikarị ya eme ihe n'ihe mkpuchi na-eguzogide kemịkalụ na ihe mkpuchi na-eguzogide okpomọkụ, ihe mgbaze silicone na ihe nrapado ziri ezi. Mgbe hydrolysis zuru oke gasịrị, a na-emepụta ntụ silicon dioxide dị oke mma, nke a na-eji emepụta phosphorus ma nwee ike iji ya dị ka ihe na-emepụta kemịkalụ.
