Strontium carbonate CAS 1633-05-2
Strontium carbonate, formula kiimikaad SrCO3, crystals prismatic aan midab lahayn ama budo cad. U beddelo habka laba geesoodka ee 926 ℃. Barta dhalaalka 1497 ℃ (6.08×106Pa), cufnaanta qaraabo 3.70. In yar oo biyo ku milmay, wax yar ku milmay xal buuxa oo kaarboon laba ogsaydh, ku milmay ammonium chloride, amooniyam amooniyam iyo xalalka kaarboonka. Waxay ka falcelisaa asiidh-dilute hydrochloric acid, nitric acid iyo acetic acid si loo sii daayo kaarboon laba ogsaydh. Wuxuu bilaabaa inuu burburo at 820 ℃, si tartiib tartiib ah luminaya carbon dioxide at 1340 ℃, oo si buuxda u qurmay strontium oxide iyo carbon dioxide kulayl cad, iyo gaasta gaari kartaa 1.01×105Pa.

1. Warshadaha elektiroonigga ah: Kaarboonayum strontium waa walxo muhiim ah oo loogu talagalay soo saarista midabka TV-ga cathode ray tubes, electromagnets, strontium ferrite cores, iwm. Waxaa loo isticmaalaa wax soo saarka capacitor-ka iyo soosaarka xusuusta kombiyuutarka elektaroonigga ah.
Wax-soo-saarka rashka: Kaarboonaysiinta Strontium waxay siin kartaa rashka saamayn holac guduudan oo gaar ah waana shay cayriin oo caan ah samaynta rashka, ololka, iwm.
2. Warshadaha dhoobada: Strontium carbonate, oo ah wax lagu daro muraayadaha dhoobada, waxay hagaajin kartaa muuqaalka iyo waxqabadka dhoobada, waxay ka dhigi kartaa dusha dhoobada mid jilicsan oo dhalaalaya, waxayna hagaajinaysaa caabbinta xirashada iyo iska caabinta dhoobada dhoobada.
3. Warshadaha Metallurgical: Strontium carbonate waxaa loo isticmaalaa in lagu hagaajiyo halabuurka iyo sifooyinka biraha. Tusaale ahaan, habka wax soo saarka ee zinc electrolytic, strontium carbonate ee ku milmay sulfuric acid waxay yarayn kartaa maadada rasaasta ee elektaroolitiga waxayna sidoo kale ka saari kartaa zinc ku dhejisan cathode.
4. Beeraha kale: Kaarboonka strontium waa alaabta ceeriin ee aasaasiga ah ee diyaarinta cusbada strontium kale. Waxa kale oo loo isticmaali karaa sida side palladium ee falcelinta hydrogenation-ka. Waxa kale oo loo isticmaalaa dawooyinka, reagennada falanqaynta, sifaynta sonkorta iyo qaybaha kale.
