Tsananguro pfupi:

Zita reChigadzirwa:

Lanthanum Oxide kugadzira|CAS1312-81-8 kupa China|4N5Kuchena Kwakakwirira

Mazwi akafanana: Lanthanum(III) oxide, Lanthana, Lanthanum trioxide

Nhamba yeCAS:1312-81-8

Fomura reMamorekuru:La2O3

Kurema kweMorekuru:325.8

Chitarisiko:Upfu huchena, haunyungudike mumvura asi unonyungudika muasidhi. Hune hygroscopic yakawanda, hunogona kupinza hunyoro nekabhoni dhayokisaidhi kubva mumhepo nekukurumidza uye hunofanira kuchengetwa mumudziyo wakavharwa.

Magadzirirwo akagadzirwa anowanikwa kana ukakumbira.

Tsananguro & Zvimiro

Tsananguro: WNX inoshandisa tekinoroji yekugadzira otomatiki yepamusoro uye inoshandisa zvinhu zvemhando yepamusoro kugadzira mhando yepamusoroLanthanum Oxide.

Zvinhu Zvikuru:

Kuchena Kwakakwirira:Lanthanum Oxide haina tsvina inobva kuzvinhu zvisingawanzoitiki zvepanyika (zvakaita sesimbi, calcium, sodium), uye huwandu hwetsvina yacho hwakaderera.

Kunyunguduka Kwakanaka:Lanthanum Oxide inogona kunyungudika nekukurumidza mumvura uye acid yakasimba.

Kuenderana: Kutarisirwa kwakasimba kwehuwandu hwezvinhu mukugadzirwa kweLanthanum Oxide inoita kuti pave nemhando yakagadzikana yekugadzira zvinhu mumaindasitiri makuru.

Girazi reOptical neCeramics: Lanthanum oxide ndiyo inonyanya kushandiswa pakugadzira magirazi eOptical nemafiber eOptical, zvichiwedzera zvakanyanya refractive index uye dispersion yegirazi. Inoshandiswa zvakanyanya mukugadzira malenzi eOptical epamusoro emakamera nemamicroscopes. Mumunda weelectronic ceramics, inoshandiswa sechinhu chinowedzera kugadzira ceramic capacitors nepiezoelectric ceramics kuti ivandudze hunhu hwemagetsi uye kugadzikana kwekupisa kwezvinhu.

Chinosimudzira: Muindasitiri yemafuta, lanthanum oxide inoshandiswa sechinhu chakakosha che catalytic cracking (FCC) catalysts, iyo inobatsira kuwedzera kubuda uye kunaka kwepeturu. Inogonawo kushanda sechinhu chinosimudzira maitiro chaiwo emakemikari, akadai sekuoxidation yecarbon monoxide uye reaction ye methane oxidation kugadzira ethane ne ethylene.

Zvinhu zvinoshanda: Lanthanum oxide ndiyo chinhu chakagadzirwa pakugadzira lanthanum boride (LaB)₆), inova chinhu chakanaka kwazvo chinoshandiswa mukugadzirwa kwe cathode ne thermoelectronic emission. Lanthanum oxide inewo mashandisirwo akakosha muminda yakadai se hydrogen storage materials uye fuel cells. Semuenzaniso, lanthanum-nickel alloys dzinogona kushandiswa kuchengetedza hydrogen.
