He aha ka Strontium carbonate CAS 1633-05-2?

ʻO ka strontium carbonate, ka hoʻohālikelike kemika SrCO3, nā kristal prismatic kala ʻole a i ʻole ka pauka keʻokeʻo. Hoʻololi i ka ʻōnaehana hexagonal ma 926 ℃. Ka helu heheʻe 1497 ℃ (6.08×106Pa), pili 3.70. Hiki ke hoʻoheheʻe ʻia i loko o ka wai, hiki ke hoʻoheheʻe ʻia i ka hopena saturated o carbon dioxide, hiki ke hoʻoheheʻe ʻia i loko o ka ammonium chloride, ammonium nitrate a me ka solution carbonic acid. Hoʻopili me ka dilute hydrochloric acid, nitric acid a me ka acetic acid e hoʻokuʻu i ke kalapona. Hoʻomaka i ka decompose ma 820 ℃, nalowale ka carbon dioxide ma 1340 ℃, a pau i ka decomposes i strontium oxide a me carbon dioxide i ka wela keʻokeʻo, a hiki i ke kinoea ke hiki i 1.01 × 105Pa.

1. Electronics 'oihana: Strontium carbonate mea nui maka mea no ka hana kala TV cathode ray paipu, electromagnets, strontium ferrite cores, a pela aku.

ʻO ka hana ahi: Hiki i ka Strontium carbonate ke hāʻawi i ke ahi i kahi hopena ʻulaʻula ʻulaʻula kū hoʻokahi a he mea maʻamau no ka hana ʻana i ke ahi, nā lapalapa, a pēlā aku.

2. ʻOihana Ceramic: ʻO Strontium carbonate, ma ke ʻano he mea hoʻohui no ka ceramic glazes, hiki ke hoʻomaikaʻi i ka hiʻohiʻona a me ka hana ʻana o nā seramika, e hoʻomaʻamaʻa i ka ʻili o ka ceramic a ʻoi aku ka māmā, a hoʻomaikaʻi i ke kūpaʻa a me ke kūpaʻa corrosion o nā seramika.

3. ʻOihana Metallurgical: Hoʻohana ʻia ʻo Strontium carbonate e hoʻoponopono i ka haku mele a me nā waiwai o nā metala. No ka laʻana, i ke kaʻina hana o ka zinc electrolytic, hiki i ka strontium carbonate i hoʻoheheʻe ʻia i ka waikawa sulfuric ke hōʻemi i ka ʻike alakaʻi i loko o ka electrolyte a hiki ke wehe i ka zinc i waiho ʻia ma ka cathode.

4. Nā kīhāpai ʻē aʻe: ʻO Strontium carbonate ke kumu kumu no ka hoʻomākaukau ʻana i nā paʻakai strontium ʻē aʻe. Hiki ke hoʻohana ʻia ma ke ʻano he mea lawe palladium no nā hopena hydrogenation. Hoʻohana ʻia i ka lāʻau lapaʻau, analytical reagents, hoʻomaʻemaʻe kō a me nā ʻano ʻē aʻe.
