Heated to 1100 ℃ decomposed into strontium oxide and carbon dioxide. Soluble in dilute hydrochloric acid and dilute nitric acid, while emitting carbon dioxide. Insoluble in water, relative density 3.5.

       Strontium CarbonateUses: used in the manufacture of color TV cathode ray tube, electromagnetic iron, strontium ferrite, fireworks, fluorescent glass, flares, etc., is also the production of other strontium salt raw materials; used as a special PTC thermistor element (switch start, degaussing, current limiting protection, constant temperature heating, etc.) production of the base powder; it is the basic raw material for producing strontium salt. As a carrier of palladium, it can be used for hydrogenation. In addition, it is also used in the production of fireworks, fluorescent glass, flares, paper, medicine, analytical reagents, as well as sugar refining, metal zinc electrolyte refining, strontium salt pigment manufacturing.
