Ukumelana namanzi nokumelana ne-asidi yengilazi ye-silicate kunqunywa ikakhulukazi okuqukethwe kwe-silica kanye ne-alkali metal oxides.Ukuphakama kokuqukethwe kwe-silica, kuyanda izinga lokuxhumana phakathi kwe-silica tetrahedron kanye nokukhula kokuzinza kwamakhemikhali engilazi.Ngokukhula kokuqukethwe kwe-alkali metal oxide, ukuzinza kwamakhemikhali engilazi kuncipha.Ngaphezu kwalokho, njengoba i-radius yama-ion ensimbi ye-alkali ikhula, amandla esibopho ayaba buthaka, futhi ukuzinza kwawo kwamakhemikhali ngokuvamile kuyehla, okungukuthi, ukumelana kwamanzi Li+>Na+>K+.
Lapho izinhlobo ezimbili zama-alkali metal oxides zikhona engilazini ngesikhathi esifanayo, ukuzinza kwamakhemikhali engilazi kudlulele ngenxa “yomphumela we-alkali oxubile”, osobala kakhulu engilazini yomthofu.
Engilazini ye-silicate ene-alkaline earth metal noma enye i-bivalent metal oxide esikhundleni se-silicon oxygen, nayo inganciphisa ukuzinza kwamakhemikhali engilazi.Kodwa-ke, umphumela wokuncipha kozinzo ubuthakathaka kunalowo wama-alkali metal oxides.Phakathi kwama-divalent oxides, i-BaO ne-PbO inomphumela onamandla kakhulu ekuzinzeni kwamakhemikhali, ilandelwa yi-MgO ne-CaO.
Engilazini eyisisekelo enokwakheka kwamakhemikhali okungu-100SiO 2+(33.3 1 x) Na2O+zRO(R2O: noma RO 2), shintsha ingxenye N azO nge-CaO, MgO, Al2O 3, TiO 2, zRO 2, BaO namanye ama-oxide futhi, ukuhleleka kokumelana kwamanzi nokumelana ne-asidi kungokulandelayo.
Ukumelana namanzi: ZrO 2>Al2O: >TiO 2>ZnO≥MgO>CaO≥BaO.
Ukumelana ne-Acid: ZrO 2>Al2O: >ZnO>CaO>TiO 2>MgO≥BaO.
Ekubunjweni kwengilazi, i-ZrO 2 ayinakho kuphela ukumelana kwamanzi nokumelana ne-asidi engcono kakhulu, kodwa futhi nokumelana okungcono kakhulu kwe-alkali, kodwa i-refractory.I-BaO ayilungile.
Ku-trivalent oxide, i-alumina, i-boron oxide ekuzinzeni kwamakhemikhali engilazi nakho kuzovela into ethi "boron anomaly".6. Ku-sodium - calcium - silicon - ingilazi kasawoti xN agO·y CaO·z SiO:, uma okuqukethwe kwe-oxide kuhambisana nokuhlobana (2-1), ingilazi ezinzile ingatholakala.
C – 3 (+ y) (2-1)
Kafushane, wonke ama-oxide angaqinisa inethiwekhi yesakhiwo sengilazi futhi enze isakhiwo siphelele futhi siminyene angathuthukisa ukuzinza kwamakhemikhali engilazi.Ngokuphambene nalokho, ukuzinza kwamakhemikhali engilazi kuzoncishiswa.
