Strontium carbonate CAS 1633-05-2
Strontium carbonate, tshuaj formula SrCO3, tsis muaj kob prismatic crystals los yog hmoov dawb. Hloov mus rau hauv hexagonal system ntawm 926 ℃. Melting point 1497 ℃ (6.08 × 106Pa), txheeb ze ntom ntom 3.70. Me ntsis soluble nyob rau hauv dej, me ntsis soluble nyob rau hauv saturated kua carbon dioxide, soluble nyob rau hauv ammonium chloride, ammonium nitrate thiab carbonic acid kua. Reacts nrog dilute hydrochloric acid, nitric acid thiab acetic acid kom tso 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 kub, thiab cov roj muaj peev xwm ncav cuag 1.01 × 105Pa.

1. Electronics kev lag luam: Strontium carbonate yog ib qho tseem ceeb raw khoom rau kev tsim xim TV cathode ray tubes, electromagnets, strontium ferrite cores, thiab lwm yam. Nws yog siv nyob rau hauv capacitor manufacturing thiab hluav taws xob computer nco ntau lawm.
Kev tsim cov foob pob hluav taws: Strontium carbonate tuaj yeem muab cov foob pob hluav taws ua rau cov nplaim taws tshwj xeeb thiab yog cov khoom siv raw rau kev ua foob pob hluav taws, hluav taws, thiab lwm yam.
2. Ceramic kev lag luam: Strontium carbonate, raws li ib tug additive rau ceramic glazes, tuaj yeem txhim kho cov tsos thiab kev ua tau zoo ntawm ceramics, ua rau cov ceramics smoother thiab brighter, thiab txhim kho cov hnav tsis kam thiab corrosion kuj ntawm ceramics.
3. Kev lag luam metallurgical: Strontium carbonate yog siv los kho cov muaj pes tsawg leeg thiab cov khoom ntawm cov hlau. Piv txwv li, nyob rau hauv cov txheej txheem ntawm electrolytic zinc, strontium carbonate yaj nyob rau hauv sulfuric acid tuaj yeem txo cov ntsiab lus ntawm cov hlau lead hauv electrolyte thiab tuaj yeem tshem tawm zinc tso rau ntawm cathode.
4. Lwm cov teb: Strontium carbonate yog cov khoom siv raw rau kev npaj lwm cov ntsev strontium. Nws kuj tseem siv tau los ua tus nqa khoom ntawm palladium rau cov tshuaj tiv thaiv hydrogenation. Nws kuj yog siv rau hauv tshuaj, tshuaj ntsuam xyuas reagents, qab zib refining thiab lwm yam teb.
