Strontium carbonate CAS 1633-05-2
Strontium carbonate, mankhwala chilinganizo SrCO3, colorless prismatic makhiristo kapena ufa woyera. Amasintha kukhala hexagonal system pa 926 ℃. Malo osungunuka 1497 ℃ (6.08 × 106Pa), kachulukidwe wachibale 3.70. Pang'ono sungunuka m'madzi, pang'ono sungunuka mu zimalimbikitsa njira ya carbon dioxide, sungunuka ammonium kolorayidi, ammonium nitrate ndi carbonic acid njira. Amachita ndi dilute hydrochloric acid, nitric acid ndi acetic acid kutulutsa mpweya woipa. Imayamba kuwola pa 820 ℃, pang'onopang'ono imataya mpweya woipa pa 1340 ℃, ndikuwola mu strontium oxide ndi carbon dioxide pa kutentha koyera, ndipo mpweya ukhoza kufika 1.01 × 105Pa.

1. Makampani opanga zamagetsi: Strontium carbonate ndizofunikira kwambiri popanga machubu amtundu wa TV cathode ray, ma electromagnets, strontium ferrite cores, etc. Amagwiritsidwa ntchito popanga capacitor ndi kupanga kukumbukira makompyuta apakompyuta.
Kupanga zozimitsa moto: Strontium carbonate imatha kupatsa zowotchera moto wofiyira wapadera ndipo ndi chinthu chodziwika bwino chopangira zozimitsa moto, zoyaka moto, ndi zina zambiri.
2. Makampani a Ceramic: Strontium carbonate, monga chowonjezera cha ceramic glazes, ikhoza kupititsa patsogolo maonekedwe ndi machitidwe a ceramic, kupangitsa kuti pamwamba pa ceramic ikhale yosalala komanso yowala, komanso kumapangitsa kuti zisawonongeke komanso kusungunuka kwa dzimbiri.
3. Makampani opanga zitsulo: Strontium carbonate imagwiritsidwa ntchito pokonza mapangidwe ndi katundu wazitsulo. Mwachitsanzo, popanga zinki ya electrolytic, strontium carbonate yosungunuka mu sulfuric acid imatha kuchepetsa lead yomwe ili mu electrolyte komanso imatha kuchotsa zinki yomwe idayikidwa pa cathode.
4. Minda ina: Strontium carbonate ndiye maziko opangira mchere wina wa strontium. Itha kugwiritsidwanso ntchito ngati chonyamulira cha palladium pakuchita kwa hydrogenation. Amagwiritsidwanso ntchito mu mankhwala, analytical reagents, shuga kuyenga ndi zina.
