Ngā Huānga Matū he Konganuku Whakawhiti
Ko ngā konganuku whakawhiti he rōpū huānga matū me ngā āhuatanga ahurei e whai tikanga ana i roto i ngā momo tono ahumahi, hangarau, me te koiora. I roto i te ripanga ā-pūmotu, ka whakanohoia ngā konganuku whakawhiti ki te poraka-d, kei roto ko ngā rōpū 3 ki te 12. Ko te ingoa "konganuku whakawhiti" i ahu mai i te kaha o ēnei huānga ki te hanga i ngā katote me ngā āhua waikura rerekē, koinei tētahi o ō rātou āhuatanga taketake. Ka matapakihia e tēnei tuhinga ngā huānga matū kei roto i ngā konganuku whakawhiti, ō rātou āhuatanga, me ētahi o ō rātou tono nui.
Ngā Āhuatanga o ngā Konganuku Whakawhiti
Hanganga Irahiko
Ko tētahi o ngā āhuatanga matua o ngā konganuku whakawhiti ko tō rātou whirihoranga irahiko. Ko te whakakī a ngā irahiko i ngā porowhita-d tētahi tohu o ēnei huānga, ā, ko te whirihoranga irahiko i roto i ēnei porowhita-d te take o te maha o ō rātou āhuatanga ā-tinana me ā-matū ahurei. Hei tauira, ko te whirihoranga irahiko o te chromium he [Ar] 3d^5 4s^1, e tohu ana i te whakakīnga wāhanga o ngā porowhita-d.
Ngā Taumata Waikura Rerekē
E mōhiotia ana ngā konganuku whakawhiti mō tō rātou kaha ki te whakaatu i te whānuitanga o ngā āhua waikura. Ko te tikanga ka taea e te huānga kotahi te hanga i ngā katote me ngā utu rerekē, he mea tino onge mō ngā huānga i waho o ngā konganuku whakawhiti. Hei tauira, ko te konupūmānehi he āhua waikura mai i te +2 ki te +7.
Te Whakaritenga Tae Uaua
He maha ngā tae whakamere o ngā matatini taunga i hangaia e ngā konganuku whakawhiti nā ngā whakawhiti d-d o ō rātou irahiko. Ko ēnei tae te hua o te mimiti o te mārama i ngā roangaru motuhake, ka puta ai te whakaoho o ngā irahiko i roto i ngā orbital-d. Hei tauira, he kikorangi te otinga parahi(II) te whanariki, ko te otinga nikara(II) te hauota he kakariki.
Ngā Āhuatanga Aukume
He āhuatanga aukume ahurei anō hoki ō ngā konganuku whakawhiti, arā, he paraaukume (he irahiko kore takirua) he ferroaukume rānei (pērā i te rino, te cobalt, me te nickel, ka taea te pupuri i te aukume). Nā ēnei āhuatanga ka nui ai te hiranga o ēnei āhuatanga i roto i ngā mahi pēnei i te hanga aukume me ngā taputapu rokiroki raraunga.
Ngā Tauira me ngā Whakamahinga o ngā Konganuku Whakawhiti
Rino (Fe)
Ko te rino te konganuku whakawhiti tino noa, ā, e whakamahia whānuitia ana i roto i te oranga o ia rā. He rerekē ngā āhua waikura o te rino, ko te mea tino noa ko te +2 (ferrous) me te +3 (ferric). Ko tētahi o ngā whakamahinga matua o te rino ko te hanga maitai, he rauemi nui i roto i te hanganga, te hanga motuka, me te maha atu o ngā hangarau.
Parahi (Cu)
He konganuku whakawhiti te parahi e mōhiotia ana mō tōna kawe hiko me te kawe wera pai rawa atu. He ātete hoki ki te waikura, ā, he whānuitia ngā whakamahinga, mai i ngā waea hiko ki ngā wāhanga hiko. Ka whakamahia hoki te parahi ki te hanga paipa wai nā tōna ātete ki te waikura.
Nickel (Ni)
Ko te nikara tētahi atu konganuku whakawhiti he tino ātete ki te waikura, ā, he maha ngā wā ka whakamahia i roto i ngā koranu hei whakanui ake i te kaha me te ātete ki te waikura. Ko tētahi o ngā whakamahinga matua o te nikara ko te hanga i te maitai kore waikura, e whakamahia ana i roto i ngā taputapu whare, ngā taputapu ahumahi, me ngā taputapu pokanga.
Konukōmiuma (Kr)
E mōhiotia whānuitia ana te chromium mō tana mahi ki te whakarato i te ātete ki te waikura me te kanapa ki ētahi atu konganuku, pērā i te whakakikorua chromium. Ko ngā āhua waikura +3 me te +6 ngā mea tino kitea. He mea nui anō hoki te chromium i roto i te hanga maitai kore waikura, ā, e whakamahia ana i roto i te umanga whakahinuhinu hiako.
Platinum (Pt)
He konganuku whakawhiti tino pumau te konukawata, kāore e tauhohe ki te nuinga o ngā matū. Nā tēnei ka tino whai hua i roto i ngā tono e hiahia ana kia ātete ki te waikura me te waikura, pērā i ngā whakakorikori motuka, ngā whakapaipai, me ngā taputapu hauora pērā i ngā taputapu whakatere.
Titanium (Ti)
He konganuku rongonui te titanium mō tōna kaha nui, tōna māmā, me tōna ātete ki te waikura. Nā ēnei āhuatanga, e whakamahia whānuitia ana te titanium i roto i te umanga rererangi, te rongoā (pērā i ngā whakatō wheua), me ngā taonga hākinakina papai.
Zirconium (Zr)
He rite te ātete o te zirconium ki te konukawata, engari he iti ake te utu, he mea pai mō ngā mahi ahumahi pēnei i ngā tauhohenga karihi me ngā matū kaha. Ka whakamahia hoki te zirconium i roto i te hanga paipa me ngā taputapu pokanga nā te mea he tino hototahi ki te koiora.
Kopa (Co)
E mōhiotia ana te Cobalt mō tōna kawe aukume, ā, e whakamahia ana i roto i te hanga aukume, pākahiko lithium-ion, me te mea hei whakakorikori i roto i te umanga matū. He mea nui anō hoki te Cobalt i roto i te hanga o ngā koranu e hiahia ana kia ātete ki te wera me te waikura.
Rūteneuma (Ru)
He konganuku whakawhiti te ruthenium e whakamahia whānuitia ana i roto i te umanga hikohiko, hei whakakorikori hoki. Hei tauira, i roto i te matū waro, ka whakamahia te ruthenium i roto i ngā tauhohenga whakakorikori ōrite, pērā i te hanga haukini.
Te Tūranga Koiora o ngā Konganuku Whakawhiti
Haunga ā rātou whakamahinga ahumahi me te hangarau, he mea nui anō hoki ētahi konganuku whakawhiti i roto i te koiora. Hei tauira, he huānga nui te rino i roto i te hemoglobin, te pūmua e kawe ana i te hāora i roto i te toto. Ka mahi te parahi i roto i ētahi whākōkī e uru ana ki te manawa pūtau. Ahakoa kei roto te konutea i te poraka-p, e kiia ana he mema o ngā konganuku whakawhiti nā tōna tūranga nui i roto i te maha o ngā whākōkī me ētahi atu mahi koiora.
Whakamutunga
He whānuitia te whānuitanga o ngā konganuku whakawhiti i roto i te ripanga ā-pūmotu, ā, he āhuatanga ahurei anō hoki ō rātou e mea nui ai rātou i roto i ngā momo mara. Mai i ngā tono ahumahi pēnei i te hanga maitai me te hikohiko ki tō rātou tūranga nui i roto i te koiora, ko ngā konganuku whakawhiti tētahi o ngā rōpū huānga tino maha ngā mahi me te pono. Mā te mārama ki ō rātou āhuatanga me ngā tono ka taea e tātou te whakamahi tonu i te pūmanawa katoa o ēnei huānga i roto i te whanaketanga hangarau me te kitenga pūtaiao a meake nei.
