Calcium sulfate hemihydrate CAS 10034-76-1
A na-akpọkwa calcium sulfate gypsum raw, gypsum siri ike raw, Muriacite, gypsum anhydrous. Kristal orthorhombic na-enweghị agba (ụdị β) ma ọ bụ kristal monoclinic (ụdị α). Ibu molekul dị n'otu 136.14. Njupụta dị n'otu 2.960. Ebe ịgbaze 1193℃ (agbanwere site na ụdị β gaa na ụdị α), 1450℃ (ụdị α, ma gbazee). Ọ na-agbaze ntakịrị na mmiri (0.209 na 20℃), ọ na-agbaze na acid, nnu ammonium, sodium thiosulfate, sodium chloride solution na glycerol. Ọ bụrụgodị na etinyere mmiri, ọ nweghịzi ike ịghọ calcium sulfate dihydrate. Ọ bụrụ na gypsum ore eke agwụla mmiri kpamkpam n'okpuru 300℃, enwere ike ịmepụta gypsum anhydrous soluble nke na-agbaze na mmiri; ọ bụrụ na gypsum eke ekpo ọkụ ruo n'elu 600℃, a na-emepụta gypsum anhydrous na-agbaze.
