I-quartz ehlanganisiwe
Ekukhiqizweni kwe-Si ne-FeSi, umthombo oyinhloko we-Si yi-SiO2, ngendlela ye-quartz.Ukusabela nge-SiO2 kukhiqiza igesi ye-SiO ephinde iphendule nge-SiC ukuya ku-Si.Ngesikhathi sokushisisa, i-quartz izoguqulela kwezinye izinguquko ze-SiO2 nge-cristobalite njengesigaba esizinzile sezinga lokushisa eliphezulu.Ushintsho ku-cristo...Funda kabanzi -
Ithonya lama-mineralizers ezindaweni zalezi zinto zobumba
I-Magnesium aluminium spinel(MgAl2O, MgO·Al2Oor MA) inezici zomshini ezisezingeni eliphezulu lokushisa eliphezulu, ukumelana okuhle kakhulu nokuxebuka kanye nokumelana nokugqwala.Kuyi-ceramic ejwayelekile yokushisa ephezulu ohlelweni lwe-Al2O-MgO.Ukukhula okuncamelayo kwe-calcium hexaaluminate (CaAl12O19, CaO·6AlO...Funda kabanzi -
Ukuthi imfucuza emsulwa ye-electroceramics ingasetshenziswa yini ukwenza i-mullite ceramics?
Eminye imfucuza yezimboni ibonakala iwusizo ekukhiqizeni izitsha zobumba ze-mullite.Lezi zimfucumfucu zezimboni zicebile ngama-oxide ensimbi athile njenge-silica (SiO2) ne-alumina (Al2O3).Lokhu kunikeza imfucuza amandla okusetshenziswa njengomthombo wokuqala wezinto ezisetshenziswayo zokulungiselela izitsha zobumba ze-mullite.I-p...Funda kabanzi
