by:Yixin     2020-12-05

1, strontium carbonate is a kind of carbonate minerals. Ling strontium ore chemical composition (SrO) SrO 70. 19%,二氧化碳29。 81%, often containing manganese, barium and calcium. 硬度35,性脆,相对密度3. 76. Is usually white, sometimes because it contains impurities, gray, yellow, white, green, or brown, white streaks. Orthorhombic system completely rhombohedron cleavage, vitreous luster, cross section is oily luster, conchoidal fracture. Soluble in dilute hydrochloric acid, produce bubbles. And galena, sphalerite and chalcopyrite associated in containing sulfide vein, also associated with calcite, dolomite and quartz.

3, strontium carbonate is heated to 1340 ℃ decomposition, emit carbon dioxide. Dissolve in water containing carbon dioxide into hydrogen strontium carbonate.
