Strontium carbonate CAS 1633-05-2
Strontium carbonate, tshuaj mis SrCO3, CAS1633-05-2, tsis muaj xim prismatic siv lead ua los yog hmoov dawb. Hloov mus rau hauv hexagonal system ntawm 926 ℃. Melting point 1497 ℃ (6.08 × 106 Pa), qhov ceev txheeb ze 3.70. Me ntsis soluble hauv dej, me ntsis soluble hauv cov kua roj carbon dioxide saturated, soluble hauv ammonium chloride, ammonium nitrate thiab carbonic acid kua. Reacts nrog dilute hydrochloric acid, nitric acid thiab acetic acid kom tso cov pa roj carbon dioxide. Pib decompose ntawm 820 ℃, maj mam poob carbon dioxide ntawm 1340 ℃, thiab tag nrho decomposes rau hauv strontium oxide thiab carbon dioxide ntawm dawb cua sov, thiab cov roj tuaj yeem ncav cuag 1.01 × 105 Pa.

1. Kev lag luam hluav taws xob: Strontium carbonate yog ib qho khoom siv tseem ceeb rau kev tsim cov xim TV cathode ray tubes, electromagnets, strontium ferrite cores, thiab lwm yam.
Strontium carbonate hmoov siv rau hauv kev tsim cov capacitor thiab kev tsim cov cim xeeb hauv computer.
Kev tsim cov foob pob hluav taws: Strontium carbonate tuaj yeem muab cov foob pob hluav taws ib qho nplaim liab tshwj xeeb thiab yog cov khoom siv raw rau kev ua cov foob pob hluav taws, nplaim taws, thiab lwm yam.
2. Kev lag luam ceramic: Strontium carbonate, ua ib qho khoom ntxiv rau cov iav ceramic, tuaj yeem txhim kho qhov tsos thiab kev ua tau zoo ntawm cov ceramics, ua rau qhov chaw ceramic du thiab ci dua, thiab txhim kho qhov hnav tsis kam thiab corrosion tsis kam ntawm cov ceramics.
3. Kev lag luam hlau: Strontium carbonate yog siv los kho cov khoom sib xyaw thiab cov yam ntxwv ntawm cov hlau. Piv txwv li, hauv cov txheej txheem tsim cov zinc electrolytic, strontium carbonate yaj hauv sulfuric acid tuaj yeem txo cov ntsiab lus txhuas hauv electrolyte thiab tseem tuaj yeem tshem tawm cov zinc tso rau ntawm cathode.
4. Lwm cov teb: Strontium carbonate yog cov khoom siv raw rau kev npaj lwm cov ntsev strontium. Strontium carbonate hmoov kuj tseem siv tau ua tus nqa palladium rau cov tshuaj hydrogenation. Strontium carbonate hmoov kuj tseem siv tau rau hauv tshuaj, tshuaj reagents, refining qab zib thiab lwm yam teb.
