Ko te uho o te oumu whakatipu tioata kotahi te taputapu matua i roto i te hanga tioata, ā, ko tōna hoahoa papa wera e pā tika ana ki te parakore me te kounga o te tioata. Hei wāhanga matua o te oumu, ka tukuna e te papa wera karāti parakore teitei te kawe wera pai rawa atu, te ātete pāmahana teitei, me te pumau matū, ka taea ai e ia te pupuri i te mahi pumau i raro i te wera nui.
Ko te mara wera he mea tito mai ingā whakamahana karāhe, ngā oko whakarewa karāhe, ngā rango whakamahana, me ētahi atu wāhanga. Mā te whakahaere tika i te tohatoha pāmahana, ka whakarite kia ōrite me te rite tonu puta noa i te tukanga tipu tioata. He tohunga te kamupene ki te rangahau, te whakawhanake, me te whakaputa i ngā mara wera karāhe tino parakore, e whakarato ana i ngā otinga wera tino mahi mō ngā oumu tipu tioata kotahi. Me te ihirangi waro o ≥99.9%, e whakamahia whānuitia ana ēnei mara wera i roto i ngā semiconductors, photovoltaics, me ētahi atu ahumahi, e tutuki ana i ngā whakaritenga pakari mō ngā tioata tino parakore.
Ko te mahi pai rawa atu o ngā mara wera karāpeti parakore-teitei e ahu mai ana i tō rātou hanganga tioata ahurei me te parakore-teitei. I te pāmahana rūma, ka whakaatuhia e te rauemi he hanganga paparanga pumau e hanga ana e ngā ngota waro he whatunga hexagonal mā roto i ngā porowhita ranu sp², e whakarato ana i te kawe hiko me te wera tino pai. I roto i ngā taiao pāmahana teitei, ka taea e ngā mara wera karāpeti parakore-teitei te tu atu i ngā pāmahana neke atu i te 1600°C me te pupuri tonu i te pumau matū, ka ārai i ngā tauhohenga ki ngā rauemi pēnei i te silicon rewa.
Mō te hanga, kei roto i te tukanga te whiriwhiri rauemi mata, te hanga, te whakapūkara, me te purenga. Ka kuruhia ngā rauemi mata, ka hurihia kia rite ki te paura iti-mā-koroni, ā, ka tangohia ngā poke pēnei i te whanariki me ngā waikura whakarewa mā te horoi waikawa. I te wā e hanga ana, ka whakapūkarahia ngā rauemi mā te whakamahi i ngā mīhini pēhi, i te hangarau pēhi isostatic rānei, ā, ko ngā pēhanga neke atu i te 200 MPa ka whakanui ake i te kiato rauemi. Ka puta te tukanga whakapūkara i roto i ngā oumu pāmahana teitei i runga ake i te 2000°C, ka taea ai e ngā ngota waro te whakarite anō me te hanga i tētahi hanganga tioata kua whakaritea. Ka whakahaerehia te purenga i roto i tētahi taiao kore-hāora pāmahana teitei mā roto i ngā tauhohenga whakapūkara, ka piki ake te ihirangi waro ki te tata ki te 99.99%.
I roto i ngā mahi whaihua, ka pāngia ngā mara wera o te karāhe parakore-teitei e ngā wero pērā i te whakahaere pāmahana me te roa o te rauemi. Mā te arotau i te hoahoa mara wera—pērā i te whakarerekē i te tohatoha hiko o ngā wāhanga whakamahana me te whakapai ake i ngā whakatakotoranga pūnaha whakamatao—ka taea te whakatutuki i te whakahaere tika o ngā pikinga pāmahana, ā, ka whakarei ake i te kounga tipu tioata. Hei tauira, mā te whakamahi i ngā rauemi whakamarumaru maha-paparanga me ngā whakatakotoranga paipa whakamatao kua arotauhia ka whakaiti i te ngaronga wera me te whakapai ake i te pai o te wera. Ka taea te whakapai ake i te roa mā roto i ngā hangarau maimoatanga mata; hei tauira, ka taea e ngā paninga silicon carbide te whakanui ake i te ātete waikura neke atu i te toru ngā wā, ka roa ake te roa o te mahi o te mara wera. Mā ēnei whanaketanga hangarau ka whakarite i te mahi pumau i roto i te oumu tipu tioata kotahi me te whakapai ake i te parakore me te ōritetanga o te tioata, ka tutuki ai ngā tono tino kaha o ngā ahumahi semiconductor me te photovoltaic.
Hei wāhanga matua o ngā oumu tipu tioata kotahi, ko te mahi a ngā mara wera karāhe teitei-parakore e whakatau tika ana i te kounga tioata me te whai huatanga o te whakaputanga. I te haere tonu o ngā whanaketanga hangarau, kei te whakapai tonu ngā tukanga hanga, ā, kei te whakarei tonuhia ngā āhuatanga o ngā rauemi. Ko ngā hangarau purenga matomato—pērā i te whakaiti i te āhua o te kohu whakarewa methanol me ngā tikanga whakaiti waiariki—ehara i te mea ka ārai noa i te parahanga taiao engari ka taea hoki te whakaputa nui. Kua noho ngā rauemi hiato, tae atu ki ngā hiato uku whakakaha-silicon carbide, hei wāhi rangahau nā te mea he pai te pumau o te wera me ngā āhuatanga miihini. I taua wā, ko te whakamahinga o te nanotechnology ka whakanui ake i te kawe wera me te mahi miihini, pērā i ngā hiato whakakaha-nanotube waro.
I te tirohanga whakamua, ka haere tonu ngā mara wera o te karāhe parakore-teitei ki te akiaki i te auahatanga i roto i te hangarau tipu tioata. Mā te rangahau me te whanaketanga tonu, ka tutukihia ngā whakapainga ake i te parakore me te kounga o te tioata, ka tutuki ai ngā hiahia o te mākete e tipu haere ana mō ngā ahumahi haurua-ira me te photovoltaic, ā, ka tautokohia hoki te hanga tioata parakore-teitei.
