I-quartz ehlanganisiwe
Ekukhiqizweni kwe-Si ne-FeSi, umthombo oyinhloko we-Si yi-SiO2, ngesimo se-quartz. Ukusabela nge-SiO2 kukhiqiza igesi ye-SiO ephendula kakhulu ne-SiC ku-Si. Ngesikhathi sokushisa, i-quartz izoguquka ibe ezinye izinguquko ze-SiO2 nge-cristobalite njengesigaba sokushisa esiphezulu esizinzile. Ukuguqulwa kube yi-cristo...Funda kabanzi -
Ithonya lama-mineralizer ezimpahleni zalezi zinto zobumba
I-Magnesium aluminium spinel (MgAl2O, MgO·Al2Oor MA) inezakhiwo zomshini ezisezingeni eliphezulu lokushisa, ukumelana okuhle kakhulu nokuxebuka kanye nokumelana nokugqwala. Yi-ceramic ejwayelekile kakhulu yokushisa okuphezulu ohlelweni lwe-Al2O-MgO. Ukukhula okuthandwa kakhulu kwe-calcium hexaaluminate (CaAl12O19, CaO·6AlO...Funda kabanzi -
Ingabe imfucuza ye-electroceramics emsulwa ingasetshenziswa yini ukuhlanganisa izinto zobumba ze-mullite?
Eminye imfucuza yezimboni iboniswa iwusizo ekukhiqizweni kwe-mullite ceramics. Le mfucuza yezimboni icebile ngama-oxide athile ensimbi njenge-silica (SiO2) kanye ne-alumina (Al2O3). Lokhu kunikeza imfucuza amandla okusetshenziswa njengomthombo wokuqala wokulungiselela i-mullite ceramics. I-p...Funda kabanzi
