Ko te ammonium cerium nitrate (CAS: 16774-21-3) he matū whenua onge cerium tetravalent noa iho, e noho ana i te āhua o ngā tioata karaka-whero. He kaha ōna āhuatanga waikura, he nui te wairewa, ā, he hototahi ki ngā tukanga, he mea nui hei rauemi matua i roto i ngā mara pēnei i te hanga hiko, te hanga rauropi, me ngā rauemi whakaterenga.
Hei kaiwhakarato matua i te ao o ngā matū whenua onge me ngā rauemi hiko kounga teitei, kua roa a Wonaixi e mahi ana i te rangahau me te whakawhanaketanga o te ammonium cerium nitrate, e whakawhirinaki ana ki tōna kaha whakaputa nui me te kounga pumau hei whakatutuki i te tuku puta noa i te ao. Me te whakataetae matua o te hangarau motuhake me te whakahaere me ngā hua ārahi o te ao, kua waihangahia e ia he otinga horopaki katoa e kapi ana i te semiconductor, te hanga rauropi, ngā rauemi catalytic me ētahi atu mara, ā, kua noho hei hoa pai mō ngā kiritaki o te ao mō te ammonium cerium nitrate.
Kua hangaia e te kamupene tētahi raina whakaputa purenga aunoa, kati, me te tino parakore, e tutuki ai te whakahaere mamati katoa mai i te purenga rauemi mata, te hanganga tika ki te whakamaroke tioata me te whakahaere kounga. He nui ngā painga o ngā hua:
- Tino parakore, tino iti hoki ngā poke: Ko te parakore o ngā hua hiko e hangaia ana e tā mātou kamupene he 99.99% – 99.999%, me ngā poke whakarewa takitahi < 0.5ppm, e tutuki katoa ana i ngā whakaritenga pakari o te hangahanga teitei.
- Te wairewatanga tino pai me te hototahitanga o ngā tukanga: He tino wairewa i roto i te wai me ngā waipiro, he otinga mārama kāore he paru, ā, he pumau mō te wā roa me te kore he paparanga, he pai mō ngā tukanga tino tika pērā i te whakairo mākū, te whakakanapa CMP, me te whakakorikori ōrite.
- Te āhua me ngā whakatakotoranga tioata: Ko ngā hua ammonium cerium nitrate i hangaia e tā mātou kamupene he āhua tioata pūmau, e whakaatu ana i te paura tioata kirikiri pai, he rite te tioata, he pai te rere, ā, he pumau te mahi.
- Taurangi whakahaere kounga mekameka katoa: Mai i ngā rauemi mata whenua onge ki te tuku hua kua oti, ka whakatinanahia he pūnaha whakahaere kounga tino pakari, me te whakaputa paerewa
ngā tukanga me te whai i te kounga o te tukanga katoa i te pūtake, me te whakahaere tika i ngā tohu matua pēnei i te āhua tioata, te parakore, te poke, te wairewatanga, me te pumau o ngā hua.
Ko te ammonium cerium nitrate, hei rauemi matua, ko te kaha whakaputa ā-tau a tā mātou kamupene me te nui o ngā taonga tuku kei roto i ngā mea tino pai o te umanga, ā, ka taea te tautoko pumau i ngā hiahia tuku nui me te roa o te ao mō ngā umanga hanga hiko matua o te ao, rongoā me te matū, whakaterenga taiao me ngā rauemi pūngao hou. Kei te pupuri tonu ā mātou hua ammonium cerium nitrate i tētahi wāhanga mākete i te taumata tuatahi i roto i te motu me te ao whānui, ā, ka kaweake ki neke atu i te 20 whenua me ngā rohe tae atu ki a Hapani, Kōrea ki te Tonga, Ūropi me Amerika.
