Matapihi Waenga Whatu Āhua Hapaira Ritenga
Kauwhata Taipitopito
He Tirohanga Whānui mō te Waenga Whatu Āhua Hapaira
He wāhanga whatu mahi-teitei tēnei āhua hapaira i hangaia mai i te hapaira karaihe kotahi (Al₂O₃), he mea hanga motuhake mō ngā tono whatu matatau e hiahia ana kia tino pakari, kia tino tika, kia mārama hoki. He tino kaha te hangarau me te māramatanga whatu o te papa āhua hapaira, he mea tino pai mō ngā taiao e kore e taea e ngā rauemi karāhe tuku iho te tu atu ki ngā āhuatanga tino kino.
Ngā Āhuatanga me ngā Painga o te Rauemi
He hoahoa tapawhā rite te āhua o te wāhanga whatu hapaira me ngā kōhao tika, i hangaia mō te whakauru ki ngā pūnaha whatu uaua. E mōhiotia ana te hapaira (Al₂O₃) mō tōna pakeketanga teitei, tuarua ki te taimana, e whakarato ana i te ātete rakuraku pai me te pumau mō te wā roa. He nui te whakawhiti whatu puta noa i te whānuitanga (UV ki te IR, 200–5000nm), he iti te birefringence, me te pumau wera tino pai, e pupuri ana i te mahi whatu ahakoa i raro i ngā pāmahana teitei me te pānga matū kino.
Ngā tono whatu
He whānuitia te whakamahinga o ngā momo hapaira pēnei i roto i ngā pūnaha whatu maha tae atu ki:
-
Ngā whatu taiaho– hei matapihi tino tika, hei tātari, hei hononga hoki i roto i ngā tautuhinga taiaho mana-tiketike.
-
Ngā pūnaha whakaahua me te pūoko– i roto i ngā taputapu whakaahua rererangi, hauora, me ngā taputapu whakaahua ahumahi, he mea tino nui te māramatanga whatu me te ātete ki te taiao.
-
Te tirotiro me te whakaahua– hei papa mō ngā paninga whatu, ngā karāhe arotahi, me ngā wāhanga hanga-hiku.
-
Ngā karu tiaki– mō ngā kāmera, ngā pūoko, me ngā taputapu whatu e pāngia ana e ngā taiao whakakorikori, pēhanga teitei rānei.

Ngā Pātai Auau mō ngā Mōhiti Quartz
P1: He aha ngā painga matua o ngā matapihi whatu hapaira kore-tika ki te whakataurite ki te quartz, ki te silica hanumi rānei?
A: He tino pakari te hapaira (Mohs 9), he ātete wera poto ki te 1900°C, me te tuku whānui 200-5500 nm, he pai ake i te quartz (te rohenga 1050°C) i ngā taiao tino kino.
Q2: He aha ngā ahumahi e whakamahi ana i ngā matapihi whatu hapaira koretake?
A: He mea nui ēnei i roto i te ao rererangi (ngā mahi whatu amiorangi), ngā endoscope hauora, ngā pūnaha laser ahumahi, me te kimi infrared parepare nā te mea he roa, he mārama hoki te tirohanga whatu.
Mō Mātou
He tohunga a XKH ki te whakawhanake hangarau teitei, te whakaputa, me te hoko i ngā karāhe whatu motuhake me ngā rauemi tioata hou. E mahi ana ā mātou hua ki ngā hiko whatu, ki ngā hiko kaihoko, me te ope taua. E tuku ana mātou i ngā wāhanga whatu Sapphire, ngā taupoki arotahi waea pūkoro, ngā uku, LT, Silicon Carbide SIC, Quartz, me ngā anga karaihe haurua-ira. Me te tohungatanga pūkenga me ngā taputapu hou, e tino matatau ana mātou ki te tukatuka hua kore-paerewa, me te whai kia noho hei hinonga hangarau teitei rauemi optoelectronic matua.
