Imwe soluble anhydrous gypsum: melting point 1450 ℃, hama density 2.89, refractive index 1.505, 1.548, inoora kana chena ichipisa. Iyo hemihydrate yaro inowanzozivikanwa se "yakapiswa gypsum" uye "platinum calciformis", kunyanya muchimiro chechena chisina-crystalline poda, ine hukama hwehukama hwe2.75. Dihydrate yaro inowanzozivikanwa se "gypsum", inova chena crystal kana upfu, ine hukama hwehukama hwe2.32, refractive index 1.521, 1.523, 1.530, uye inorasikirwa nemvura yese yekristaro kana yapisa kusvika 163 ℃. Chemicalbook Inonyungudika zvishoma mumvura, hydrochloric acid, nitric acid, inonyungudika mune inopisa sulfuric acid, isinganyunguriki mudoro. Zvigadzirwa zvechisikigo zvinonyungudika mualkaline sulfate, sodium thiosulfate, uye ammonium munyu aqueous mhinduro. Kugadzirira nzira: Natural anhydrous gypsum inowanikwa nekuita CaO uye SO3 pasi pekupisa mutsvuku. Soluble anhydrous gypsum inowanikwa nekudziisa CaSO4 · 2H2O kuhuremu hwekugara pa200 ℃. Hemihydrate inowanikwa ne calcining uye dehydrating mbishi gypsum. Dihydrate inowanikwa nekuita calcium chloride neammonium sulfate. Kushandiswa kukuru kwe calcium sulfate: Natural anhydrous gypsum inonyanya kushandiswa mumishonga; soluble anhydrous gypsum inogona kushandiswa sekushongedza kwemukati, uye inogonawo kushandiswa kugadzira makemikari, zvinwiwa, nezvimwe; hemihydrate inonyanya kushandiswa mukuvaka zvinhu, uye inogonawo kushandiswa kugadzira gypsum zvidhori uye ceramic zvinhu; dihydrate yayo inoshandiswa kugadzira hemihydrate, fillers, nezvimwe.
