Strontium carbonate CAS 1633-05-2
Strontium carbonate, fuala'au vaila'au SrCO3, tioata e leai ni lanu po'o le pa'epa'e pa'epa'e. Su'e ile fa'aonoono ile 926℃. Liu liusuavai 1497 ℃ (6.08×106Pa), fa'atusatusaga 3.70. E solu teisi i le vai, solute teisi i le vaifofo tumu o le carbon dioxide, soluble i le ammonium chloride, ammonium nitrate ma le carbonic acid solution. E fa'afeagai ma fa'ama'i fa'ama'i vai, nitric acid ma le acetic acid e fa'asa'oloto ai le carbon dioxide. Amata ona pala i le 820 ℃, faasolosolo lemu le carbon dioxide i le 1340 ℃, ma malepe atoa i le strontium oxide ma carbon dioxide i le vevela paʻepaʻe, ma e mafai ona oʻo atu le kesi i le 1.01 × 105Pa.

1. Alamanuia faaeletonika: Strontium carbonate o se mea mataʻina taua mo le gaosiga o lanu TV cathode ray tubes, electromagnets, strontium ferrite cores, ma isi. E faʻaaogaina i le gaosiga o le capacitor ma le gaosiga o manatuaga komepiuta faaeletonika.
Faiga afi: Strontium carbonate e mafai ona tuʻuina atu i le afi se afi mumu uiga ese ma o se mea masani masani mo le faia o mea faʻapipiʻi, mumu, ma isi.
2. Alamanuia Ceramic: Strontium carbonate, e avea o se faʻaopoopoga mo glazes sima, e mafai ona faʻaleleia foliga vaaia ma le faʻatinoga o ceramics, faʻalelei ma susulu le sima, ma faʻaleleia le faʻaogaina o le ofuina ma le faʻafefeteina o keramika.
3. Alamanuia Metallurgical: Strontium carbonate e faʻaaogaina e faʻafetaui ai le tuʻufaʻatasiga ma meatotino o metala. Mo se faʻataʻitaʻiga, i le faʻagasologa o le gaosiga o le zinc electrolytic, strontium carbonate ua faʻamavaeina i le sulfuric acid e mafai ona faʻaitiitia ai le taʻitaʻi i totonu o le electrolyte ma e mafai foi ona aveese le zinc na teuina i luga o le cathode.
4. O isi fanua: Strontium carbonate o le mea fa'avae autu mo le sauniaina o isi masima strontium. E mafai foi ona faʻaaogaina e avea o se ave o palladium mo faʻamaʻi hydrogenation. E faʻaaogaina foʻi i vailaʻau, suʻesuʻega suʻesuʻe, faʻamamaina suka ma isi matāʻupu.
