Suoyi Factory Spherical chromium oxide CAS 1308-38-9

ʻO Chromium oxide (Cr2O3) he mea hoʻohuihui ʻole

1. Nānā: ʻO ka Chromium oxide kahi'ōmaʻomaʻo crystalline'ōmaʻomaʻo a iʻole ka pauka.

2. Ka helu heheʻe a me ka paila: ʻO ka helu heheʻe o ka chromium oxide ma kahi o 2435 ° C, a ʻoi aku ka nui o ka paila ma mua o 4000 ° C.

3. Density: ʻO ka nui o ka chromium oxide ma kahi o 5.22 g/cm ³.

4. Nā waiwai kemika: ʻO Chromium oxide kahi pūhui paʻa loa i hiki ʻole ke hoʻoheheʻe ʻia i ka wai a me ka hapa nui o nā mea hoʻoheheʻe. He kūpaʻa kiʻekiʻe ia i ka waikawa a me ka alkali. Eia kekahi, ʻoi aku ka maikaʻi o ka chromium oxide a me ke kūpaʻa wela kiʻekiʻe.

Nui nā hoʻohana ʻana o Chromium oxide

1. Pigment: Ma muli o kona'ōmaʻomaʻo'ōmaʻomaʻo'ōmaʻomaʻo, hoʻohana mauʻiaʻo ia e like me ka puaʻa'ōmaʻomaʻo i nāʻoihana e like me ka ceramics, ke aniani, ka uhi, a me ka plastic.

2. Hoʻopaʻa hoʻoheheʻe: Hiki ke hoʻohana ʻia ka Chromium oxide ma ke ʻano he mea hoʻokaʻawale no ke kila, nā mea hao, a me nā metala ʻē aʻe e hoʻonui i ko lākou ola.

3. Catalyst: Hiki ke hoʻohana ʻia ka Chromium oxide ma ke ʻano he catalyst i nā hopena kemika, e like me nā hopena o ka ammonia.

4. Nā mea uila: Ma muli o kāna mau waiwai uila maikaʻi loa, hoʻohana nui ʻia ka chromium oxide i nā mea uila, nā mea magnetic, a me nā uhi optical.

Nui nā ʻano hana no ka hana ʻana i ka chromium oxide:

1. Keʻano hoʻoheheʻe wela: E wela a hoʻoheheʻe i ka wai paʻakai chromium e hana i ka chromium oxide.

2. ʻO ke ala hoʻoheheʻe: E hoʻohana i ka oxygen e hoʻoheheʻe i ka chromium metala i loko o ka chromium oxide.

3. Keʻano wai wela: Hoʻopili ka paʻakai Chromium me ka wai e hana i nā kristal ma lalo o nā kūlana wela a me ke kaomi.

I ka hoʻohana ʻana i ka chromium oxide, pono e hoʻomaopopo ʻia kēia mau ʻike palekana:

1. He mea ʻawaʻawa ka Chromium oxide, e pale i ka hoʻohu ʻana i nā ʻāpana a hōʻike i ka ʻili.

2. I ka wā o ka hana ʻana, pono e hoʻohana ʻia nā lako pale pilikino kūpono e like me nā mīkina lima a me nā maka maka.

3. E hō'ole i ka hui 'ana me nā mea 'akika a i 'ole nā ​​mea hiki ke ho'ā 'ia e pale aku i ka hana 'ana i nā kinoea 'awa'awa a i 'ole ke ahi.

4. I ka wā e mālama ai, pono e hoʻopaʻa ʻia e pale aku i ka pili ʻana me nā mea kemika ʻē aʻe.
