"Ko te kounga pai te tīmatanga; ko te ratonga te mea nui; ko te whakahaere te mahi tahi" koinei tā mātou rapunga whakaaro hinonga e whaihia ana, e whaia ana hoki e tā mātou kamupene mō te utu iti o Haina Teitei Te Ātete Pāmahana Molybdenum Graphite Crucible Metal Melting Pot, e whakapono ana mātou! E mihi ana mātou ki ngā tumanako hou ki tāwāhi ki te whakatū hononga kamupene, ā, e tumanako ana hoki mātou ki te whakakotahi i ngā hononga me ngā kiritaki kua roa e tū ana.
"Ko te kounga pai te tīmatanga; ko te ratonga te mea nui; ko te whakaritenga te mahi tahi" koinei tā mātou rapunga whakaaro hinonga e puritia ana, e whaia ana hoki e tā mātou kamupene mō ngā rā katoa.Para Molybdenum Haina, Ngā Paraihe hei Hoko, Ka whakaratohia e mātou he ratonga wheako, he whakautu tere, he tuku wā tika, he kounga pai me te utu pai rawa atu ki ā mātou kiritaki. Ko te makona me te nama pai ki ia kiritaki tā mātou kaupapa matua. Ka arotahi mātou ki ngā taipitopito katoa o te tukatuka ota mō ngā kiritaki kia tae rā anō ki a rātou ngā hua haumaru me te ora, me te ratonga kawe pai me te utu ōhanga. I runga i tēnei, ka tino hokona ā mātou taonga ki ngā whenua o Āwherika, te Waenganui-Rawhiti me te Tonga-Rawhiti o Āhia. I runga i te piripono ki te rapunga whakaaro pakihi "kiritaki tuatahi, haere whakamua", ka mihi nui mātou ki ngā kiritaki mai i te kāinga me tāwāhi ki te mahi tahi me mātou.
Ngā mea whakakotahi waro / waro(e kiia nei i muri nei ko ""C / C, CFC rānei") he momo rauemi hiato e ahu mai ana i te waro, ā, e whakapakaritia ana e te muka waro me ōna hua (muka waro kua oti te hanga). He rite tōna āhua ki te waro, he rite hoki tōna kaha ki te muka waro. He pai ōna āhuatanga miihini, he ātete wera, he ātete waikura, he ārai waku, he pai hoki ōna āhuatanga kawe wera me te hiko.
CVD-SiCKo ngā āhuatanga o te paninga he hanganga ōrite, he rauemi kiato, he ātete pāmahana teitei, he ātete waikura, he parakore teitei, he ātete waikawa me te kawakore me te matū matū waro, me ngā āhuatanga ā-tinana me te matū pumau.
Ki te whakatauritea ki ngā rauemi karāpeti parakore-teitei, ka tīmata te karāpeti ki te waikura i te 400C, ka ngaro te paura nā te waikura, ka hua ake te parahanga taiao ki ngā taputapu taha me ngā rūma korehau, ka piki ake hoki ngā poke o te taiao parakore-teitei.
Heoi, ka taea e te paninga SiC te pupuri i te pumau ā-tinana me te matū i te 1600 nekehanga, he mea whakamahi whānuitia i roto i te ahumahi hou, inā koa i roto i te ahumahi semiconductor.
Ka whakaratohia e tā mātou kamupene ngā ratonga tukanga paninga SiC mā te tikanga CVD i runga i te mata o te karāpeti, te uku me ētahi atu rauemi, kia tauhohe ai ngā hau motuhake kei roto te waro me te silicon i te pāmahana teitei hei whiwhi i ngā ngota SiC parakore teitei, ka whakatakotoria ngā ngota ki runga i te mata o ngā rauemi pania, ka hanga he paparanga tiaki SIC. Ka piri pūmau te SIC i hangaia ki te turanga karāpeti, ka hoatu he āhuatanga motuhake ki te turanga karāpeti, nā reira ka hanga te mata o te karāpeti kia kiato, kia kore he porosity, kia ātete ki te pāmahana teitei, kia ātete ki te waikura me te ātete ki te waikura.
Ngā āhuatanga matua:
1. Ātete waikura pāmahana teitei:
He tino pai tonu te ātete ki te waikura ahakoa te teitei o te pāmahana ki te 1600 C.
2. Teitei o te parakore: i hangaia mā te whakatakotoranga kohu matū i raro i te āhuatanga whakapūkara pāmahana teitei.
3. Ātete ki te horo: he pakeke teitei, he mata kiato, he matūriki angiangi.
4. Ātete ki te waikura: waikawa, kawakore, tote me ngā matū waro.
