Yintoni iStrontium carbonate CAS 1633-05-2?

I-Strontium carbonate, i-chemical formula SrCO3, iikristale zeprismatic ezingenambala okanye umgubo omhlophe. Iguqulela kwisixokelelwano esine-hexagonal kwi-926℃. Indawo yokunyibilikisa i-1497℃ (6.08×106Pa), ukuxinana kwe-3.70. I-soluble kancinane emanzini, i-soluble kancinane kwisisombululo se-carbon dioxide, i-soluble kwi-ammonium chloride, i-ammonium nitrate kunye nesisombululo se-carbonic acid. Iphendula kunye ne-dilute hydrochloric acid, i-nitric acid kunye ne-acetic acid ukukhulula ikharbon dayoksayidi. Iqala ukubola kwi-820 ℃, ngokuthe ngcembe ilahlekelwa yi-carbon dioxide kwi-1340 ℃, kwaye idibanise ngokupheleleyo kwi-strontium oxide kunye ne-carbon dioxide kubushushu obumhlophe, kwaye igesi inokufikelela kwi-1.01 × 105Pa.

Isicelo

1. Imboni yezobuchwephesha: I-Strontium carbonate yinto ebalulekileyo ekrwada kwimveliso yombala weTV ye-cathode ray tubes, i-electromagnets, i-strontium ferrite cores, njl.

Ukwenziwa komlilo: I-Strontium carbonate inokunika i-fireworks isiphumo esikhethekileyo somlilo obomvu kwaye sisixhobo esiqhelekileyo sokwenza izixhobo zomlilo, ukuvutha, njl.

2. Ishishini le-Ceramic: I-Strontium carbonate, njengesongezo se-ceramic glazes, inokuphucula ukubonakala kunye nokusebenza kwee-ceramics, yenza i-ceramic surface ibe lula kwaye ikhanyise, kwaye iphucule ukunyanzeliswa kokugqoka kunye nokuxhatshazwa kwe-corrosion ye-ceramics.

3. Imboni ye-Metallurgical: I-Strontium carbonate isetyenziselwa ukulungelelanisa ukubunjwa kunye neempawu zetsimbi. Ngokomzekelo, kwinkqubo yokuvelisa i-electrolytic zinc, i-strontium carbonate echithwe kwi-asidi ye-sulfuric inokunciphisa umxholo okhokelayo kwi-electrolyte kwaye inokususa i-zinc efakwe kwi-cathode.

4. Amanye amabala: I-Strontium carbonate yimathiriyeli ekrwada esisiseko yokulungiselela ezinye iityuwa ze-strontium. Isenokusetyenziswa njengomphathi we-palladium kwiimpendulo ze-hydrogenation. Ikwasetyenziselwa amayeza, ii-reagents zohlalutyo, ukucokisa iswekile kunye nezinye iinkalo.
