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.Te Hauhāuriki Cerium.

Ngā Āhuatanga Matua:

Teitei o te Parakore:Te Hauhāuriki Cerium 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:Te Hauhāuriki Cerium 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 oTe Hauhāuriki Cerium e whakarite ana i te kounga pumau mō te whakaputanga ahumahi nui.

Whakakōkī ahumahi matū: Cerium tetrafluoride (CeF₄) he matū whakapūkara kaha, ā, e whakamahia ana hei whakakorikori i roto i ngā tauhohenga maha i roto i te hanganga rauropi, pērā i te whakapūkara whiriwhiri o ngā waipiro ki ngā ketone me te whakapūkara tika o te methane me te whanariki toruora hei whakaputa waikawa methanesulfonic. He mea tino nui tōna āhuatanga whakapūkara i raro i ngā āhuatanga waikawa, ā, ka taea te whakamahi hei matū whakapūkara kotahi-irahiko whai hua. Cerium trifluoride (CeF₃) e whakamahia ana hei wāhanga whakakorikori i roto i te pakaru whakakorikori hinu (FCC) hei whakapai ake i te whai huatanga o te hurihanga o ngā hauwaiwaro.

Karāhe Motuhake me ngā Rauemi Whatu: Cerium trifluoride (CeF₃) he rauemi mata matua mō te hanga karāhe whatu tino tika, ka taea te whakapai ake i te mahi mimiti ultraviolet o te karāhe, ā, e whakamahia ana hei paura whakakanapa karāhe me te whakaiti i te aro. Cerium tetrafluoride (CeF₄) e whakamahia ana i roto i te paninga whatu, e whakarato ana i te mahi ārai-whakaata tino pai mō ngā karu me ngā whakaata, e whakarei ake ana i te pakari me te mahi a ngā taputapu whatu. E whakamahia ana ēnei e rua hei rauemi scintillator i roto i ngā whakamātautau ahupūngao kaha-tiketike me ngā mara kimi irahiko.

Ngā Pūhiko me ngā Rauemi Pūngao: Cerium trifluoride (CeF₃) e whakamahia ana hei rauemi manaaki whanariki i roto i ngā pākahiko lithium-whanariki. Ko tōna hanganga nanocage ahurei (h-CeF₃) ka taea te whakarei ake i te mahi huringa o te pākahiko mā te pānga mahi tahi o te here ā-tinana me te mimiti matū. Tetrafluorocerium (CeF₄) he rauemi pea mō ngā kaiārahi ion fluoride, ā, ka taea te whakamahi hei whakawhanake i ngā pākahiko ion fluoride totoka-āhua, e kaha ana ki te whakatutuki i te kiato pūngao teitei ake. Kei te rangahauhia hoki te cerium trifluoride hei rauemi electrolyte mō ngā pūtau wahie waikura totoka (SOFC).

Ngā takawaenga hanga matū: He mea nui ngā matū mua o te cerium trifluoride me te cerium tetrafluoride mō te hanga i ētahi atu pūhui cerium. Ko te cerium trifluoride te rauemi mata mō te hanga cerium whakarewa, ko te cerium tetrafluoride ka taea te whakaputa mā te tauhohenga whakaiti mai i te cerium trifluoride. Hei tāpiri, ka taea te whakamahi i te cerium trifluoride hei hanga i ngā rauemi nano-luminescent kua tāpirihia ki te cerium (pērā i te CeF₃:Tb³⁺), e whakamahia ana i roto i ngā hangarau whakaahua me te whakaatu koiora.
