Material Properties
Safiri ikristaro imwe chete aluminium oxide (Al2O3) Icho chimwe chezvinhu zvakaoma zvikuru. Safire ine yakanaka kutapurirana maitiro pamusoro pezvinooneka, uye pedyo neIR spectrum. Inoratidza simba rakakwirira remagetsi, kushandiswa kwemakemikari, kupisa kwekushisa uye kugadzikana kwekushisa. Inowanzo shandiswa semidziyo yemahwindo mune chaiyo ndima senge nzvimbo tekinoroji uko kukwenya kana kupisa kwakanyanya kunodiwa.
