Ubuhlalu bengilazi ngokuyinhloko bakhiwe nge-silicon dioxide engasebenzi (SiO₂), evamise ukudlula ama-65%. Futhi aqukethe amanye ama-oxide, njenge-sodium oxide (Na₂O) ne-calcium oxide (CaO). Isilinganiso salezi zingxenye sithinta izakhiwo ezingokomzimba namakhemikhali zobuhlalu bengilazi.
Ubuhlalu bengilazi, izinto ezincane ezibonakala zilula kodwa eziguquguqukayo, zinokuningi kwesayensi yezinto ezibonakalayo kanye nobuchwepheshe benqubo. Ngakho-ke, yini ngempela ubuhlalu bengilazi benziwe?
Indwangu Eyinhloko: I-Silica Engenayo
Ubuhlalu bengilazi ngokuyinhloko bakhiwe nge-silicon dioxide engasebenzi (SiO₂), inhlanganisela ye-inorganic enamakhemikhali aphezulu kakhulu nokuzinza okushisayo. I-silicon dioxide ivamise ukubala ngaphezu kuka-65% wengqikithi yobuhlalu bengilazi futhi iyisici esibalulekile sokwakheka kwayo. Ngenxa yemvelo engasebenzi ye-silicon dioxide, ubuhlalu bengilazi bubonisa ukugqwala okuhle kakhulu nokumelana nokugqokwa, kugcina ukusebenza okuzinzile ezindaweni ezihlukahlukene ezinokhahlo.
Ezinye Izingxenye Ze-Oxide: Ngaphezu kwe-silicon dioxide, ubuhlalu bengilazi bubuye buqukethe inani elithile lamanye ama-oxide, njenge-sodium oxide (Na₂O), i-calcium oxide (CaO), i-magnesium oxide (MgO), ne-aluminium oxide (Al₂O₃). Lawa ma-oxide adlala indima ekulawuleni izakhiwo ezingokoqobo namakhemikhali zobuhlalu bengilazi. Isibonelo, ukungezwa kwe-sodium oxide ne-calcium oxide kunganciphisa izinga lokushisa elincibilikayo lengilazi futhi kwandise ukuncibilika kwayo, ngaleyo ndlela kube lula ukubunjwa nokucubungula ubuhlalu bengilazi. I-Magnesium oxide ne-aluminium oxide, ngakolunye uhlangothi, ikhulisa ubulukhuni nokumelana nokugqoka kwengilazi, ngaleyo ndlela yandise impilo yesevisi yobuhlalu bengilazi.
