Scandium fluoride 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 pom kev siv hluav taws xob siab. 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
