Strontium carbonate CAS 1633-05-2
Strontium carbonate, foromo ea lik'hemik'hale SrCO3, likristale tse se nang mebala tsa prismatic kapa phofo e tšoeu. E fetoha tsamaiso ea hexagonal ho 926 ℃. Sebaka se qhibilihang ke 1497 ℃ (6.08×106Pa), sekhahla se lekanyelitsoeng 3.70. E qhibiliha hanyenyane ka metsing, e qhibiliha hanyenyane ka tharollo e tletseng carbon dioxide, e qhibilihang ka ammonium chloride, ammonium nitrate le carbonic acid solution. E arabela ka dilute hydrochloric acid, nitric acid le acetic acid ho lokolla carbon dioxide. E qala ho bola ka 820 ℃, butle-butle e lahleheloa ke carbon dioxide ho 1340 ℃, 'me e senyeha ka ho feletseng ka strontium oxide le carbon dioxide mocheso o mosoeu,' me khase e ka fihla 1.01 × 105Pa.

1. Indasteri ea elektronike: Strontium carbonate ke thepa ea bohlokoa e tala bakeng sa ho etsa mebala ea TV cathode ray tubes, electromagnets, strontium ferrite cores, joalo-joalo E sebelisoa ho etsa capacitor le tlhahiso ea memori ea k'homphieutha ea elektronike.
Ho etsa li-fireworks: Strontium carbonate e ka fa li-fireworks phello e ikhethang ea lelakabe le lefubelu 'me ke lisebelisoa tse tloaelehileng tsa ho etsa li-fireworks, flares, joalo-joalo.
2. Indasteri ea Ceramic: Strontium carbonate, e le tlatsetso ea likhalase tsa ceramic, e ka ntlafatsa ponahalo le ts'ebetso ea li-ceramics, ea etsa hore bokaholimo ba ceramic bo be boreleli le bo khanyang, 'me e ntlafatse ho hanyetsa ho apara le ho hanyetsa kutu ea li-ceramics.
3. Indasteri ea metallurgic: Strontium carbonate e sebelisetsoa ho fetola sebopeho le thepa ea tšepe. Ka mohlala, ts'ebetsong ea tlhahiso ea zinki ea electrolytic, strontium carbonate e qhibilihisitsoeng ka sulfuric acid e ka fokotsa karolo ea loto ka electrolyte hape e ka tlosa zinki e behiloeng holim'a cathode.
4. Masimo a mang: Strontium carbonate ke thepa ea motheo e tala bakeng sa ho lokisa letsoai le leng la strontium. E ka boela ea sebelisoa e le sesebelisoa sa palladium bakeng sa karabelo ea hydrogenation. E boetse e sebelisoa ho tsa bongaka, li-analytical reagents, ho hloekisa tsoekere le masimo a mang.
