Chii chinonzi Strontium carbonate CAS 1633-05-2?

Strontium carbonate, kemikari formula SrCO3, isina ruvara prismatic makristasi kana chena poda. Inoshandura kuita hexagonal system pa926 ℃. Melting point 1497 ℃ (6.08 × 106Pa), hukama density 3.70. Inonyungudika zvishoma mumvura, inonyungudika zvishoma muyakazara mhinduro yecarbon dioxide, soluble muammonium chloride, ammonium nitrate uye carbonic acid solution. Inopindirana ne dilute hydrochloric acid, nitric acid uye acetic acid kuburitsa carbon dioxide. Inotanga kuora pa820 ℃, zvishoma nezvishoma inorasikirwa nekabhoni dioxide pa1340 ℃, uye inopera zvachose kuva strontium oxide uye carbon dioxide pakupisa kwakachena, uye gasi rinogona kusvika 1.01 × 105Pa.

Application

1. Indasitiri yemagetsi: Strontium carbonate chinhu chakakosha chekugadzira ruvara rweTV cathode ray tubes, electromagnets, strontium ferrite cores, etc. Inoshandiswa mukugadzira capacitor uye electronic computer memory production.

Kugadzira fireworks: Strontium carbonate inogona kupa fireworks yakasarudzika dzvuku murazvo mhedzisiro uye yakajairika mbishi yekugadzira mafirework, flare, nezvimwe.

2. Ceramic industry: Strontium carbonate, sechinhu chinowedzera chekeramic glazes, inogona kuvandudza kutaridzika uye kushanda kwekeramics, kuita kuti nzvimbo yekeramic iite zvakanaka uye inopenya, uye inovandudza kusapfeka uye kusagadzikana kwemarara emakeramiki.

3. Metallurgical industry: Strontium carbonate inoshandiswa kugadzirisa kuumbwa uye zvinhu zvesimbi. Semuyenzaniso, mukugadzirwa kwe electrolytic zinc, strontium carbonate yakanyungudutswa mu sulfuric acid inogona kuderedza mutobvu uri mu electrolyte uye inogonawo kubvisa zinc yakaiswa pa cathode.

4. Mimwe minda: Strontium carbonate ndiyo yakakosha zvinhu zvekugadzira mamwe strontium munyu. Inogona zvakare kushandiswa semutakuri wepalladium kune hydrogenation maitiro. Inoshandiswawo mukurapa, analytical reagents, kuchenesa shuga uye mamwe minda.
