Te rauemi whakakanapa makutu

  I te ao o te hanga tino tika me te whakaotinga mata,waikura ceriumKua ara ake te paura whakakanapa hei rauemi e whakarerekē ana i te ao. Nā ōna āhuatanga ahurei he mea nui ki te whānuitanga o ngā mahi whakakanapa, mai i ngā mata ngawari o ngā karāhe whatu ki ngā anga hangarau teitei i roto i te hanga haurua-ira.

  He ranunga whakamīharo o ngā tukanga matū me ngā tukanga miihini te tikanga whakakanapa o te cerium oxide.waikura cerium (CeO₂) ka whakamahia ngā āhua uara rerekē o te huānga cerium. I te aroaro o te wai i te wā o te tukanga whakakanapa, ko te mata o ngā rauemi pēnei i te karāhe (he nui te hanga o te silica, SiO₂) ka whakakōkōhia.CeO₂kātahi ka tauhohe ki te mata silica hydroxylated. Ka hangaia tuatahitia he here Ce – O – Si. Nā te āhua hydrolytic o te mata karāhe, ka huri anō tēnei hei Ce – O – Si(OH)₃here

   I roto i te mīhini, ko te mārō, te paiherewaikura ceriumHe rite ngā matūriki ki ngā mea whakakoi ririki. Ka waruhia e rātou ngā mea koretake o te mata o te rauemi. I te neke haere o te papa whakakoi puta noa i te mata i raro i te pēhanga, kawaikura ceriumKa huri ngā matūriki i ngā tihi, ka āta whakatāpiri i te mata. He wāhi anō tā te kaha miihini ki te motu i ngā here Si – O – Si i roto i te hanganga karāhe, ka āwhina i te tango i ngā rauemi i te āhua o ngā kongakonga iti.Ko tētahi o ngā āhuatanga whakamīharo owaikura ceriumko te whakakanapa ko tōna kaha ki te whakarite i te tere o te whakakanapa. Ina taratara te mata o te rauemi, ko tewaikura ceriumKa kaha te tango a ngā matūriki i te rauemi i te tere teitei. I te mea ka maeneene haere te mata, ka taea te whakarerekē i te tere oro, ā, i ētahi wā, ka tae ki te āhua "mutu-ā-unoa". Nā te taunekeneke i waenga i te waikura cerium, te papa oro, me ngā tāpiringa i roto i te paru oro tēnei. Ka taea e ngā tāpiringa te whakarerekē i te matū o te mata me te piri i waenga i tewaikura ceriumngā matūriki me te rauemi, e whakahaere pai ana i te tukanga oro.
