I roto i te maha o ngā wheketere, ko ētahi o ngā taputapu matua, pērā i ngā anga hau, ngā awaawa, ngā tuke, ngā mowhiti waha o te tinana papu, me ētahi atu, ka tere te pakaru nā te mimiti o ngā wai kei roto he totoka tere-rahi. Ahakoa kāore i te nui ēnei 'wāhi ngāwari ki te mau', ka pā tika tonu ki te whai huatanga o te mahi me te auau whakaweto o ngā taputapu. I tēnei rā ka kōrero tātou mō ngā pare iti i hangaia kia "tū atu" ki ēnei pakaru me te haehae –poraka ātete-kakahu silicon carbide.
Tērā pea ētahi e pātai, he aha te take e whakamahia ai te "silicon carbide" hei hanga poraka ātete-kakahu? He tino māmā te whakautu. Tuatahi, he "pakeke". He tino pakari te silicon carbide, tuarua ki te taimana, ā, ka taea te tu atu ki te horo o ngā matūriki tere-rahi mō te wā roa; Ko te 'pūmautanga' te mea whai āhuatanga matū pumau, ā, he ātete ki te waikura waikawa me te kawakore, ā, e kore e 'kai' e te maha o ngā pāpāho ahumahi; Anō, he 'ātete-wera', ka taea te mahi pumau i ngā pāmahana teitei ake, ā, kāore e ngawari te pakaru i te aroaro o ngā huringa pāmahana. Ko te mea nui ake, he maeneene te mata me te iti o te tauwehenga waku, e kore e whakaiti noa i te kakahu engari ka whakaiti hoki i te ātete wai, ka āwhina i ngā taputapu kia pai ake te whakamahi pūngao.
Ko te tāuta i ngā poraka ātete-kakahu silicon carbide ki ngā "wāhi ngāwari ki te kakahu" o ngā taputapu he rite ki te whakatakoto i tētahi paparanga o te "pūeru huna" ki runga i ngā taputapu. Ko te painga tino tika ko te whakaroa i te roa o te ora o ngā taputapu, te whakaiti i te maha o ngā kati me ngā whakakapinga, me te whakaiti i ngā utu tiaki; Tuarua, te whakaū i te tukanga whakaputa kia kore ai e heke te whai huatanga, e poke rānei te hua i puta mai i te kakahu me te haehae ā-rohe; I taua wā anō, nā tōna āhua me tōna rahi ka taea te whakarite kia rite ki te āhuatanga tūturu o ngā taputapu, he ngāwari hoki, he rerekē hoki te tikanga tāutanga. Ahakoa he mea whakau ki ngā pūtu, he mea here rānei ki te piripiri motuhake, ka taea te whakatutuki i te piri pai, kia kore ai e ngawari te taka i raro i te waikura nui.
Heoi anō, kia tino mahi ai te poraka ātete-kakahu, he mea nui anō hoki te whiriwhiri me te tāutanga. Hei tauira, me whiriwhiri te momo me te hanganga tika o te silicon carbide i runga i te rahi o te matūriki, te tere rere, te pāmahana, me ngā āhuatanga matū o te rauemi; i te wā tāutanga, kia ma te mata, kia piri pai hoki kia kore ai e pāngia e te kukū ahotea i puta mai i te "pānga kaha"; i te wā e whakamahia ana, ngana ki te pupuri i ngā āhuatanga mahi pumau, me te karo i ngā rerekētanga nui o te rere me te kukū. Mā te mahi pai i ēnei, ka nui ake te roa o te ora me te whai huatanga o te poraka ātete-kakahu.
I te nuinga o te wā, he otinga "iti mō te nui" ngā poraka ātete-kakahu silicon carbide: ehara i te mea nui te rahi, engari ka taea te tiaki i ngā taputapu nui me te tiaki i te mahi whakaputa tonu. Mena kei te raru koe i ngā raruraru kakahu ā-rohe i roto i te mahi whakaputa, ka hiahia pea koe ki te ako mō ngā poraka ātete-kakahu silicon carbide me te kite me pēhea e taea ai e rātou te "whakaiti i te taumahatanga" o ō taputapu me te "tāpiri i ngā tohu" ki tō kaha whakaputa.
