Whakaahuatanga me ngā Āhuatanga

Whakaahuatanga: Ka whakamahia e WNX te hangarau whakaputa aunoa matatau, ā, ka whakamahia ngā rauemi mata kounga teitei hei whakaputa i te kounga teitei.Waikura Lanthanum.

Ngā Āhuatanga Matua:

Teitei o te Parakore:Waikura Lanthanum kāore he poke o ngā huānga whenua onge (pērā i te rino, te konupūmā, te konutai), ā, he iti noa te nui o te poke.

Te Wairewatanga Pai:Waikura Lanthanum ka tere te memeha i roto i te wai me ngā waikawa kaha.

Te Pūmautanga: Te whakahaere pakari o ngā puranga i roto i te whakaputanga oWaikura Lanthanum e whakarite ana i te kounga pumau mō te whakaputanga ahumahi nui.

Karāhe whatu me ngā uku: Ko te waikura lanthanum te rauemi matua mō te hanga karāhe whatu me ngā muka whatu tino tika, e whakarei ake ana i te taupū whakaata me ngā āhuatanga marara o te karāhe. He whānuitia te whakamahinga i roto i te hanga karāhe whatu matatau mō ngā kāmera me ngā karu hiko. I roto i te mara o ngā uku hiko, ka whakamahia hei tāpiri ki te hanga pūnga uku me ngā uku piezoelectric hei whakapai ake i ngā āhuatanga hiko me te pumau o te pāmahana o ngā rauemi.

Kaiwhakaoho: I roto i te umanga matū hinu, ka whakamahia te waikura lanthanum hei wāhanga nui o ngā kaiwhakaoho pakaru catalytic (FCC), e āwhina ana ki te whakapiki i te putanga me te kounga o te penehīni. Ka taea hoki te mahi hei kaiwhakaoho mō ngā tauhohenga matū motuhake, pērā i te waikura o te hauota waro me te tauhohenga o te waikura methane hei hanga i te ethane me te ethylene.

Ngā rauemi mahi: Ko te waikura lanthanum te rauemi mata mō te whakarite i te lanthanum boride (LaB₆), he rauemi pai rawa atu tēnei mō te tukunga hikohiko wera. He mea nui anō hoki ngā whakamahinga o te waikura lanthanum i roto i ngā mara pēnei i ngā rauemi rokiroki hauwai me ngā pūtau wahie. Hei tauira, ka taea te whakamahi i ngā koranu lanthanum-nickel mō te rokiroki hauwai.
