Lanthanum Fluoride CAS 13709-38-1
ʻO ka pauda keʻokeʻo, ka nui 5.936. Ka helu heheʻe 1493 ℃, kahi paila 2330 ℃, hiki ʻole ke hoʻoheheʻe ʻia i ka wai, paʻakikī ke hoʻoheheʻe i loko o ka waikawa hydrochloric, ka waikawa nitric a me ka waikawa sulfuric, akā hiki ke hoʻoheheʻe ʻia i ka waikawa perchloric. Hygroscopic i ka ea, ʻoi aku ka paʻa.
Hoʻohana ʻia no ka hoʻomākaukau ʻana i ka scintillator, nā mea laser crystal crystal, fluoride glass optical fiber a me nā aniani infrared earth i koi ʻia e ka ʻenehana hōʻike kiʻi lapaʻau hou a me ka ʻepekema nuklea. Hoʻohana ʻia ia no ka hana ʻana i ke kukui arc carbon electrode i ke kumu kukui. Hoʻohana ʻia i ka nānā ʻana kemika e hana i nā electrodes koho ion fluoride.
Hoʻopaʻa ʻumeke: 1, 2, 5, 25, 50 kg / ʻāpana, pahu pahu pahu pahu: 25, 50 kg / ʻāpana, ʻeke ʻeke i ulana ʻia: 25, 50, 500, 1000 kg / ʻāpana.
