He papanga ngohengohe karāhe parakore teitei
Taipitopito Tere:
1. Ētahi atu ingoa: he mea hanga ki te karāhe ngāwari, he mea hanga ki te mara wera haurua-haurua, he mea hanga ki te karāhe.
2. Taupānga: Te whakamarumaru o te mara wera o te semiconductor, ngā taputapu photovoltaic, te oumu tinei hau pēhanga teitei korehau, te oumu silicon monoclistallin me ētahi atu whakamarumaru taputapu pāmahana teitei.
3. Ngā tawhā matua: te parakore ≥99.99%, te pāmahana manawanui mōrahi 3000℃, te kawe wera 0.15-0.24W/m·K.
Whakaahuatanga
He kaihanga matua a Semixlab mō te whariki ngohengohe karāhe parakore teitei i Haina, e arotahi ana ki te whakarato i ngā otinga whakamahana wera mahi teitei mō ngā mara ahumahi semiconductor, photovoltaic me te pāmahana teitei. He rauemi mata karāhe parakore teitei kua kawemaihia mai i tēnei hua (te ihirangi poke ≤0.1%), he mea hanga ki te hanganga whatunga muka mā te tukanga motuhake, ā, he āhuatanga matua pērā i te kawe wera tino iti (≤ 0.25W /m·K i te 1000℃), te ātete pāmahana tino teitei (te pāmahana whakamahi tonu o te 3000℃) me te koretake o te matū, he rauemi pai mō te hanga pūnaha mara wera tino tika.
Ko te whatu ngohengohe karāpeti tino parakore te rauemi matua mō te pūnaha papa wera o ngā taputapu haurua-ira me te photovoltaic. Mā te raranga tika me te whakarārangi o ngā muka karāpeti tino parakore, ka hangaia he hanganga pūwero me te kawe wera iti. I roto i ngā taiao pāmahana teitei (hei tauira, neke atu i te 800 ℃), ka whakaitihia te ngaronga wera mā te whakaata i te wera hihi me te whakaiti i te ara whakawhiti wera totoka.
E ai ki te rerekētanga o ngā rauemi mata, ka wehea ngā hua ki ngā momo e toru:
He mea hanga ki te karāhe ngohengohe PAN: he tino pai ngā āhuatanga hangarau, he māmā te tukanga whakaputa, he whānuitia te whakamahinga i roto i ngā rauemi tautoko hanganga.
He papanga ngohengohe i hangaia ki te karāhe viscose: he kaha te ātete ki te tango, he uaua te hangarau, he pai mō te wāhi whakamahana wera pāmahana teitei.
He ngohengohe te huruhuru karāhe e hangai ana ki te papa: he nui ngā rauemi mata, he nui te hua waro, engari he whaiti te tono mākete.

tono
1. Ngā taputapu hanga hiko haurua
Pūnaha tipu silicon karaihe kotahi:
I roto i te oumu karaihe kotahi tikanga CZ, ka takaihia te whakamahana karāpeti me te oko kiripaka kia tika ai te whakahaere i te pikinga pāmahana rewa (te rerekētanga pāmahana tuaka ≤2℃/cm) me te whakarite i te pumau o te tere tipu karaihe kotahi.
Omu tipu karaihe silicon carbide:
Ina whakamahia te tikanga PVT, ka taea e te papanga ngohengohe hei paparanga whakamahana matua te whakanui ake i te ōritetanga o te papa wera tuaka i roto i te oumu mā te 40%, me te whakaiti i te tere o te koha karaihe ki < 0.5/cm².
2. Ngā taputapu ahumahi photovoltaic
Ouma ingota Polycrystalline:
Ka whakapai ake te hoahoa huihuinga modular i te pai o te wera o te oumu ki te 85%, arā, he 30% te penapena pūngao ki te whakataurite ki te muka waro mārō tuku iho.
3. Ngā taputapu ahumahi pāmahana teitei
Ka piki ake te tere whakamatao o te arai whakamahana i roto i te rūma whakamahana o te oumu tinei hau pēhanga teitei korehau mā te 20%.
Mā te pūnaha hiri hihiri i roto i te rohe sintering o te oumu sintering korehau ka whakaiti i te whakamahinga hau argon mā te 15%.
Painga whakataetae
