Yog dab tsiScandium Oxidesiv rau?
Scandium Oxide, tseem hu ua Scandia, tau txais kev siv dav hauv ntau yam lag luam vim nws cov khoom tshwj xeeb physico-chemical. Nws yog cov khoom siv raw rau Al-Sc alloys, uas tau txais kev siv rau tsheb, nkoj thiab aerospace. Nws yog qhov tsim nyog rau cov khoom ntsuas siab ntawm UV, AR thiab bandpass coatings vim nws cov nqi ntsuas siab, pob tshab, thiab txheej hardness ua rau muaj kev puas tsuaj siab tau tshaj tawm rau kev sib xyaw nrog silicon dioxide lossis magnesium fluoride rau kev siv hauv AR. Scandium Oxide kuj tseem siv rau hauv kev txheej txheem kho qhov muag, catalyst, hluav taws xob ceramics thiab laser kev lag luam. Nws kuj tseem siv txhua xyoo hauv kev ua cov teeb pom kev zoo siab. Ib qho khoom dawb yaj siab siv rau hauv cov kab ke kub siab (rau nws txoj kev tiv thaiv cua sov thiab thermal shock), hluav taws xob ceramics, thiab iav sib xyaw.
