Kev siv ntawm Scandium sulfate:
Scandium Sulfate yog siv nyob rau hauv optical txheej, catalyst, hluav taws xob ceramics thiab laser kev lag luam. Nws kuj tseem siv tau txhua xyoo los ua cov teeb hluav taws xob siv hluav taws xob ntau. Lub siab melting dawb khoom siv nyob rau hauv high-temperature systems (rau nws tsis kam mus rau tshav kub thiab thermal shock), hluav taws xob ceramics, thiab iav muaj pes tsawg leeg. Haum rau kev siv lub tshuab nqus tsev vacuum
