Te Porowhita Kapiti Hiraka / Te Whakaata mō ngā Tirohanga Āhuarangi Whero
Kauwhata Taipitopito
Tirohanga Whānui
Ko te whakaata papatahi silicon carbide (SiC) he wāhanga whatu kounga teitei i hangaia mai i te uku SiC matatau. He tino pai te ōwehenga pakari-ki-taumaha, he pai ake te mahi infrared, me te pakari taiao, he kōwhiringa pai mō ngā pūnaha whatu uaua. Ki te whakatauritea ki ngā rauemi tuku iho pēnei i te silica hanumi, te germanium, me te zinc selenide, ehara i te mea he pai noa iho ngā whakaata SiC i roto i te whānuitanga infrared waenga ki tawhiti, engari he mama hoki, he kaha miihini teitei, me te pumau mo te wa roa i raro i ngā tikanga mahi uaua.
E whakamahia whānuitia ana tēnei whakaata i roto i ngā utauta rererangi, ngā pūnaha taiaho, ngā whakaahua pūwhero-whero, me te ine tika-teitei.
Ngā Āhuatanga Matua
-
Te arotautanga hanganga māmāMā te hoahoa matatau me ngā hanganga honikoma me te āhua o te whare ka whakaitihia te taumaha me te kore e whakararu i te kaha. -
Tino māmāHe mama ake i ngā papa whakaata tuku iho, he mea nui mō ngā papa rererangi me ngā papa pūkoro.
-
Te pakari teitei: Ka mau tonu te tika o te ahua o te mata ahakoa ngā whirihoranga whakaata-rahi me te whakaata-angiangi.
-
Te whakawhānui wera iti: Ka whakamana i te mahi whatu ahakoa ngā rerekētanga pāmahana tere, tino kino rānei.
-
Ātete ki te rakuraku me te kakahuHe pakari tata ki te taimana, ātete ki te waikura o te taiao.
-
Te whakaoti mata tino tikaPapatahi ≤ 1 μm, he pai te kounga o te mata mō ngā mahi whakaahua uaua me te whakamahi i te taiaho.
Ngā Painga Mahi
-
Teitei o te modulus me te pumau o ngā āhuatangaTe rerekētanga ngāwari tae atu ki te 420–450 GPa, e whakarite ana i te mahi pumau i raro i ngā kawenga taumaha me ngā wiri.
-
Te iti o te whakapōrearea weraHe tino iti te tauwehenga o te whakawhānui wera (CTE), e whakarite ana i te pumau whatu i roto i ngā taiao wera rerekē.
-
Te ātete ki te ru wera me te waikuraHe pumau ki ngā taiao waikawa/kawakore, ā, he ātete hoki ki ngā piki me ngā heke o te pāmahana.
-
Hanganga iti, kikī, kāore he pūweroTe mātotoru papatipu tae atu ki te 3.14 g/cm³ me te kore he porosity toenga i muri i te miihini, e whakarato ana i te whakaata pai me te pumau hanganga.

Ngā Pātai Auau
P1: He whakaata te whakaata SiC i roto i ngā roangaru e kitea ana?
A1: He mātotoru te papa o raro, engari mā te whakamahi i ngā paninga whakaata tika (whakarewa, whakakino rānei), ka taea e ngā whakaata papatahi SiC te mahi pai i roto i ngā roangaru e kitea ana, e pūwhero ana, tae atu ki ngā roangaru taiaho.
Q2: He aha ngā painga o te SiC i runga i te karaihe, i te whakarewa rānei?
A2: He mama ake, he pakari ake, he pumau ake hoki te SiC i ngā papa karāhe, whakarewa rānei. He pakari ake hoki i roto i ngā taiao uaua, ātea rānei.
Q3: Ka taea te whakamahi i ngā whakaata papatahi SiC i roto i ngā tono taiaho mana-tiketike?
A3: Ae. He pai rawa te kawe wera me te pumau ā-pūkaha, ā, he pai rawa ngā papa SiC mō ngā whakaata taiaho mana-teitei, pūngao-teitei rānei ina honoa ki ngā paninga e tika ana.
P4: He aha te taumata o te papatahi ka taea te whakatutuki?
A4: I muri i te oro tino tika, ka taea te papatahi te eke ki te ≤ 1 μm, me te whakahaere i te whakarara me te taratara o te mata kia tutuki ai ngā whakaritenga whatu pakari.
