Omaka bomkhiqizo

Incazelo Yomkhiqizo

Impushana ebomvu e-amorphous, iba mnyama lapho imile kanye nekristalu ekushiseni;amafomu e-vitreous kanye ne-colloidal angase alungiswe.

Ifomu le-amorphous liyathamba ku-40 °C futhi lincibilike ku-217 °C.Akuvamile ukwenzeka esimweni sawo semvelo, noma njengezinhlanganisela ezihlanzekile ze-ore.

Izinzuzo Zethu

I-Rare-earth-scandium-oxide-inenani-elihle-2

Isevisi esingayinikeza

1) Inkontileka esemthethweni ingasayinwa

2) Isivumelwano sokugcinwa kuyimfihlo singasayinwa

3) Isiqinisekiso sokubuyiselwa imali sezinsuku eziyisikhombisa

Okubaluleke nakakhulu: asikwazi ukunikeza umkhiqizo kuphela, kodwa isevisi yesixazululo sobuchwepheshe!
