Ka taea te whakamahi i te karāpiti hei mata pene, hei tae, hei mea whakakanapa, ā, i muri i te tukatuka motuhake, ka taea te hanga mai i ngā momo rauemi motuhake, hei whakamahi i roto i ngā rāngai ahumahi e pā ana. Nō reira, he aha te whakamahinga motuhake o te paura karāpiti? Anei tētahi tātaritanga māu.
He pai te pumau matū o te paura graphite. I muri i te tukatuka motuhake, he pai te ātete ki te waikura, he pai te kawe wera, he iti te uruhanga, he whānui te whakamahinga i roto i te hanga whakawhiti wera, tāke tauhohenga, pūwhakamātao, pourewa mura, pourewa mimiti, pouaka whakamatao, whakamahana, tātari, me ngā taputapu papu. He whānui te whakamahinga i roto i te hanga matū hinu, te hanga wai, te hanga waikawa me te kawakore, te muka hangai, te pepa me ētahi atu ahumahi, ā, ka taea te whakaora i te maha o ngā rauemi whakarewa.
Mō te whakarewa, te whakarewa konumohe, te whakahāngai me ngā rauemi whakarewa pāmahana-teitei: nā te mea he iti te tauwehenga whānui wera o te karāhe, ā, ka taea te huri i te pānga wera, ka taea te whakamahi hei pokepoke karāhe, mā te whakamahi i te karāhe pango whakarewa karāhe he tika te rahi, he maeneene te mata me te hua teitei, kāore e taea te tukatuka, te tukatuka paku rānei, kia penapena ai i te nui o te konganuku. Ko te hanga paura karāhe sima, he mea hanga i te nuinga o te wā mai i te rauemi karāhe, ka whakakoihia ki ngā oko porcelain. Ko ngā oumu tipu karaihe, pērā i te silicon monocrystalline, ngā oko whakamahine rohe, ngā taputapu whāiti, ngā whakamahana whakaawe, me ētahi atu, ka tukatukahia mai i te karāhe tino parakore. Hei tāpiri, ka taea hoki te whakamahi i te karāhe hei papa whakamahana karāhe whakarewa korehau me te turanga, ngongo oumu ātete pāmahana-teitei, pae, pereti, whatunga me ētahi atu wāhanga.
Ka taea hoki e te karāpiti te ārai i te tauine o te kōhua, e whakaatu ana ngā whakamātautau e pā ana ko te tāpiri i tētahi nui o te paura karāpiti ki roto i te wai (tata ki te 4~5 karamu mō ia tana wai) ka taea te ārai i te tauine o te mata kōhua. Hei tāpiri, ka taea te whakamahi i te karāpiti ki roto i ngā auahi whakarewa, ngā tuanui, ngā piriti me ngā paipa.
Hei tāpiritanga, ko te karāhe, te karāhe rānei me te pepa i roto i te umanga māmā, he mea hanga ki te pene, ki te waituhi, ki te peita pango, ki te waituhi me te taimana hangai, he rauemi mata nui te taimana. He rauemi tino pai hei penapena pūngao me te tiaki taiao, kua whakamahia e te Hononga o Amerika hei pākahiko waka. I te whanaketanga o te pūtaiao me te hangarau hou me te umanga, kei te whānui haere tonu te tono o te karāhe, kua noho hei rauemi mata nui i roto i te mara hangarau teitei o ngā rauemi hiato hou, ā, he tūranga nui kei roto i te ōhanga o te motu.
Whakamahia i roto i te umanga pūngao atomika me te umanga ārai ā-motu: he pai te paura karāpiti kei roto i ngā tauhohenga atomika, he nui ake te whakamahinga o te tauhohenga karāpiti uranium i roto i te tauhohenga atomika. Hei rauemi whakaheke tere mō te tauhohenga karihi, me teitei te ira rewa, te pumau me te ātete ki te waikura, ā, ka taea e te paura karāpiti te whakatutuki i ngā whakaritenga o runga ake nei. He tino parakore te karāpiti e whakamahia ana i roto i ngā tauhohenga atomika, ā, kaua e neke ake i te tekau ngā wāhanga ia miriona o ngā poke. Ina koa, me iti iho i te 0.5PPM te ihirangi o te polone. I roto i te umanga ārai, ka whakamahia hoki te paura karāpiti hei hanga i ngā pūwero mō ngā rōkete wahie totoka, ngā kōne ihu mō ngā pere, ngā wāhanga mō ngā taputapu whakatere ātea, te whakamarumaru wera, me ngā rauemi tiaki irahiko.
