Dab tsi yogScandium oxidesiv rau?
Scandium oxide, tseem hu ua scandia, tau txais cov ntawv thov dav hauv ntau qhov kev lag luam vim nws cov tshuaj tshwj xeeb physico-tshuaj lom neeg. Nws yog cov khoom siv raw rau al-sc alloys, uas tau txais rau lub tsheb, nkoj thiab aerospace. Nws yog tsim nyog rau lub siab ntsuas ntawm UV, AR thiab cov khoom siv hardpass, pob zeb ua kom zoo nkauj, thiab cov tshuaj fluoride siab lossis magnesium rau hauv ar. Scandium oxide tseem siv rau hauv cov txheej txheem kho qhov muag, catalyst, hluav taws xob ceramics thiab laser kev lag luam. Nws kuj yog siv ib xyoos ib zaug hauv kev ua kom muaj lub siab hloov kho teeb meem. Ib lub siab melting dawb khoom siv siv nyob rau hauv high tshuab-tshuab (rau nws kev tiv thaiv kom sov thiab thermal poob siab), hluav taws xob ceramics, thiab iav muaj pes tsawg leeg.
