Imwe soluble anhydrous gypsum: melting point 1450℃, relative density 2.89, refractive index 1.505, 1.548, inoora kana chena ichipisa. Hemihydrate yayo inowanzozivikanwa se "burned gypsum" uye "platinum calciformis", kunyanya muchimiro chewhite non-crystalline powder, ine relative density ye2.75. Dihydrate yayo inowanzozivikanwa se "gypsum", inova white crystal kana powder, ine relative density ye2.32, relative index 1.521, 1.523, 1.530, uye inorasikirwa nemvura yese yecrystal kana yapiswa kusvika 163℃. Chemicalbook Inonyungudika zvishoma mumvura, hydrochloric acid, nitric acid, inonyungudika muhot sulfuric acid, hainyungudike mualcohol. Zvigadzirwa zvechisikigo zvinonyungudika mualkaline sulfate, sodium thiosulfate, uye ammonium salt aqueous solutions. Nzira yekugadzira: Gypsum yemusikirwo inonyungudika inowanikwa nekuita CaO3 neSO3 pasi pekupisa kutsvuku. Gypsum yemusikirwo inonyungudika inowanikwa nekupisa CaSO4·2H2O kusvika pahuremu hunogara huripo pa200℃. Hemihydrate inowanikwa nekuita calcining uye kubvisa mvura mu gypsum isina kuchena. Dihydrate inowanikwa nekuita calcium chloride ne ammonium sulfate. Mashandisirwo makuru ecalcium sulfate: Gypsum yemusikirwo inonyungudika inonyanya kushandiswa mukurapa; gypsum yemusikirwo inonyungudika inogona kushandiswa sekushongedza kwemukati, uye inogona kushandiswawo kugadzira makemikari, zvinwiwa, nezvimwewo; hemihydrate inonyanya kushandiswa muzvinhu zvekuvaka, uye inogonawo kushandiswa kugadzira gypsum statues nezvinhu zveceramic; dihydrate yayo inoshandiswa kugadzira hemihydrate, fillers, nezvimwewo.
