Isicelo
I-Cerium chloride heptahydrate, ezinhlotsheni ze-crystalline aggregates noma izigaxa eziphuzi ezikhanyayo, iyimpahla ebalulekile ye-catalyst, ingilazi, i-phosphors kanye nezimpushana zokupholisha. Ibuye isetshenziselwe ukwenza ingilazi ishintshe umbala ngokugcina insimbi isesimweni sayo esisansimbi. Ikhono lengilazi ye-Cerium-doped ukuvimba ukukhanya kwe-ultra violet lisetshenziswa ekwenzeni ingilazi yezokwelapha namafasitela asemkhathini. Ibuye isetshenziselwe ukuvimbela ama-polymer ukuthi angabi mnyama ekukhanyeni kwelanga kanye nokucindezela ukuguquguquka kwengilazi yethelevishini. Isetshenziselwa izingxenye ze-optical ukuthuthukisa ukusebenza. I-Cerium chloride ingu-used ezimbonini ezifana nama-petroleum catalysts, ama-catalysts e-exhaust yezimoto, ama-intermediate compounds, njll. Isetshenziselwa futhi ukwenza i-cerium yensimbi, njll. I-Cerium chloride isetshenziswa ezimbonini ezifana ne-pharmaceutical intermediates, izinto zokusetshenziswa zikasawoti we-cerium, izithasiselo ze-alloy eqinile, namakhemikhali. ama-reagents

Ukupakishwa:Iphakethe le-vacuum 1, 2, 5, 25, 50 kg/piece, iphakethe lebhakede lekhadibhodi 25, 50 kg/piece, isikhwama esilukiweyo esipakishwayo 25, 50, 500, 1000 kg/piece.
Qaphela:Ukukhiqizwa komkhiqizo kanye nokupakishwa kungenziwa ngokuya ngokucaciswa komsebenzisi.
Indlela yokulungiselela:Chaza i-cerium carbonate esixazululweni se-hydrochloric acid, uhwamuke uze wome, bese uhlanganisa insalela ne-ammonium chloride. I-Calcine ekushiseni okubomvu, noma shisa i-cerium oxalate emfudlaneni wegesi ye-hydrogen chloride, noma shisa i-cerium oxide emfudlaneni wegesi ye-carbon tetrachloride.
