Iyini i-Strontium carbonate CAS 1633-05-2?

I-Strontium carbonate, ifomula yamakhemikhali i-SrCO3, amakristalu eprismatic angenambala noma impushana emhlophe. Iguqulela ohlelweni lwe-hexagonal ku-926 ℃. Iphoyinti elincibilikayo 1497℃ (6.08×106Pa), ukuminyana kwesihlobo 3.70. Incibilika kancane emanzini, incibilika kancane kusisombululo esigcwele se-carbon dioxide, i-soluble ku-ammonium chloride, i-ammonium nitrate nesixazululo se-carbonic acid. Isabela nge-dilute hydrochloric acid, i-nitric acid ne-acetic acid ukuze ikhiphe isikhutha. Iqala ukubola ku-820 ℃, kancane kancane ilahlekelwa i-carbon dioxide ku-1340 ℃, futhi ibole ngokuphelele ibe yi-strontium oxide ne-carbon dioxide ekushiseni okumhlophe, futhi igesi ingafinyelela ku-1.01 × 105Pa.

Isicelo

1. Imboni yezogesi: I-Strontium carbonate iyinto ebalulekile yokukhiqiza amashubhu e-TV cathode ray, ama-electromagnets, ama-strontium ferrite cores, njll. Isetshenziswa ekukhiqizeni i-capacitor nasekukhiqizeni inkumbulo yekhompyutha ye-elekthronikhi.

Ukukhiqiza iziqhumane: I-Strontium carbonate inganikeza iziqhumane umphumela ohlukile welangabi elibomvu futhi iyimpahla evamile yokukhiqiza iziqhumane, ama-flares, njll.

2. Imboni ye-Ceramic: I-Strontium carbonate, njengesengezo se-ceramic glaze, ingathuthukisa ukubukeka nokusebenza kwezitsha zobumba, yenze ubuso be-ceramic bushelelezi futhi bukhanye, futhi ithuthukise ukumelana nokuguga nokumelana nokugqwala kwezitsha zobumba.

3. Imboni ye-Metallurgical: I-Strontium carbonate isetshenziselwa ukulungisa ukwakheka kanye nezakhiwo zezinsimbi. Isibonelo, enqubweni yokukhiqiza i-electrolytic zinc, i-strontium carbonate encibilikisiwe ku-sulfuric acid inganciphisa okuqukethwe komthofu ku-electrolyte futhi ingaphinda isuse i-zinc efakwe ku-cathode.

4. Eminye imikhakha: I-Strontium carbonate iyisisekelo sokusetshenziswa kosawoti we-strontium. Ingasetshenziswa futhi njengesithwali se-palladium ngokusabela kwe-hydrogenation. Ibuye isetshenziswe kwezokwelapha, ama-reagents okuhlaziya, ukucwenga ushukela neminye imikhakha.
