Gypsum kale oo anhydrous milmaya: barta dhalaalka 1450 ℃, cufnaanta qaraabo 2.89, index refractive 1.505, 1.548, qudhuntaa marka caddaanku kulul yahay. Hemihydrate-keeda waxaa caadi ahaan loo yaqaan "gypsum gubtay" iyo "platinum calciformis", oo u badan qaabka budada cad ee aan crystalline ahayn, oo leh cufnaanta qaraabada ah 2.75. Fuuq-baxa waxa loo yaqaan "gypsum", kaas oo ah crystal cad ama budo, oo leh cufnaanta qaraabada ah ee 2.32, index refractive 1.521, 1.523, 1.530, oo lumisa dhammaan biyaha crystal marka lagu kululeeyo 163 ℃. Buuga Kiimikada Waxoogaa ku milmay biyaha, aashitada hydrochloric, nitric acid, ku milmay asiidhka sulfuric ee kulul, aan lagu milmi karin khamriga. Alaabooyinka dabiiciga ah waxay ku milmaan alkaline sulfate, sodium thiosulfate, iyo ammonium milix xalal aqueous ah. Habka diyaarinta: Gypsum anhydrous dabiiciga ah waxaa lagu helaa iyada oo ka falcelinaysa CaO iyo SO3 kulaylka gaduudan hoostiisa. Gypsum anhydrous milmaya waxaa lagu helaa kuleylinta CaSO4 · 2H2O ilaa miisaanka joogtada ah 200 ℃. Hemihydrate waxaa lagu helaa calcining iyo fuuqbaxa gypsum ceeriin ah. Dihydrate waxaa lagu helaa ka falcelinta calcium chloride leh ammonium sulfate. Isticmaalka ugu muhiimsan ee kalsiyum sulfate: Gypsum anhydrous dabiiciga ah ayaa inta badan loo isticmaalaa daawada; Gypsum anhydrous milmaya waxaa loo isticmaali karaa qurxinta gudaha, waxaana sidoo kale loo isticmaali karaa in lagu sameeyo kiimikooyin, cabitaanno, iwm.; hemihydrate waxaa inta badan loo isticmaalaa qalabka dhismaha, waxaana sidoo kale loo isticmaali karaa in lagu sameeyo sawirada gypsum iyo alaabta dhoobada; fuuq-baxahiisa waxa loo isticmaalaa in laga sameeyo hemihydrate, buuxinta, iwm.
