Ko ngā rauemi matua o te karāhe photovoltaic ko: te onepu silica, te pungarehu houra, te dolomite, te toka kōhatu, te hauwai konumohe, te mirabilite, te konutai nitrate, te konutai pyroantimonate, me ētahi karāhe pakaru kua hangarua. Nā ngā whakaritenga motuhake mō te whakawhiti mārama o te karāhe photovoltaic, ko te tikanga me iti te ihirangi rino o ia rauemi mata, ā, he iti te rino o te rauemi mata, kia whiwhi ai i te whakawhiti mārama teitei.
1. Te onepu hiraka, te wāhanga matua o te hiraka, te mātāpono whānui mō te kōwhiringa wheketere
11 Te nui o te SiO2 me te pumau.
1.2 He iti te ihirangi Fe2O3 me te Al2O3, ā, he pumau.
1.3 Kāore he matūriki ātete ahi, pērā i te chromite me ētahi atu poke.
1.4 Rahi matūriki e tika ana, kaua he matūriki nunui, ā, he nui rawa te paura angiangi.
1.5 Te pumau o te makuku.
Ngā whakaritenga taupū motuhake
A. Te hanganga matū:
| Ihirangi | SiO2 | Al2O3 | Fe2O3 | LOI | Makuku |
| % | ≥99.3±(0.4) | ≤0.3±(0.1) | ≤0.008 | ≤0.15 | ≤5.0 |
Mena he whare rokiroki whakaōrite, ka taea te whakangawari i te whakahaere me te whakahaere wai kia tutuki ai ngā whakaritenga o te whāngai ki roto i te rokiroki whakaōrite.
B. Te tohatoha matūriki
| mm | 1.0 | 0.71 | 0.50 | 0.125 | -0.125 |
| % | Kore | ≤Kore | ≤5.0 | ≥90.0 | ≤10.0 |
Mō te tohatoha rahi o te matūriki, e whakaatu ana ētahi tuhinga ka taea te whakangawari i te paerewa paura pai ki te 15%, engari me whai whakaaro ki te momo oumu. Mena he oumu hāora-katoa, ka taea te whakangawari, engari ki te mea he oumu hau, kaua e whakangawari, kia kore ai e ārai te paura pai i te whatunga ka rere atu, ka puta he hapa mā. Ko te ine rewa o te onepu silica he > 1800℃. Mena he nui ake ngā matūriki, ka puta pea te āhuatanga o te kore rewa (i runga i te nui o te kukume me te tere rewa o te oumu).
I tēnei wā, ko ngā pūtake matua o te onepu silica ko: te rohe o Fengyang, te Porowini o Anhui, te Porowini o Wenchang, te Porowini o Hainan, te rohe o Hepu, te Beihai, te Zhanjiang, me te rohe o Heyuan. I tāwāhi, kei reira ngā onepu Initonīhia, Mareia, Vietnamese me Ahitereiria. I roto i te uaua o fengyang me te heyuan, ko te kounga o te konganuku quartz te wā whakamutunga mō te whakakorenga o te kaolin, ka hangaia he kirikiri onepu kia pakaru anō (hei tauira, hepu, he onepu Zhanjiang), ko te onepu moana anō (ko te nuinga o te wā he titanium dioxide kāore e tangohia, e whakaitihia rānei, he pakaru te oumu, ā, ko ngā toenga titanium dioxide i roto i te karāhe ka arahi ki te hekenga o te whakawhiti mārama UV o te karāhe).
2. Ko te houra tunutunu, ko ngā wheketere karaihe te nuinga o te wā e whiriwhiri ana i te houra tunutunu taumaha, te wāhanga matua o te konutai warowaihā, e whai wāhi ana ki te whakakotahitanga, ko tōna matotoru me te onepu silica ki roto i te hononga, ko ngā whakaritenga whānui a te wheketere mō ngā paerewa kounga houra tunutunu me ngā mātāpono whiriwhiri ko ēnei e whai ake nei:
2.1 Te nui o te Na2CO3
2.2 He iti te ihirangi o te NaCl me te Fe2O3
2.3 Rahi matūriki e tika ana, ā, karekau he poke, he mea e piri ana.
Ngā whakaritenga taupū motuhake
A. Ngā whakaritenga kai:
| Ihirangi | Na2CO3 | NaCl | Ngaronga | Fe2O3 |
| % | ≥99.0 | ≤0.50 | ≤0.50 | 0.0030 |
5. Ko te konumohe hauwai, te nuinga o ngā wāhanga alumina e whakaratohia ana, ko te kaha o te karāhe hei whakarei ake i te mahi, engari ko te nui o te ihirangi alumina ka arahi pea ki te whakamārama rewa o te āhuatanga rawakore, me tino tupato te whakanui ake, ko ngā whakaritenga whānui o te ahumahi o te ihirangi alumina karāhe photovoltaic i roto i te 0.95-1.05% pea, ka taea te whiwhi mahi tapahi pai me ngā whakaritenga kaha. Nā te mea he ngāwari ake te rewa o te konumohe hauwai i te alumina, ā, ka taea te whakaputa i ngā ngota wai hei tuku, hei whakarei ake i te whakamārama, nō reira ko te nuinga o te wheketere he whiriwhiri i te konumohe hauwai hei rauemi mata hei whakauru i te hanganga alumina. Heoi, kua whakaatuhia e ngā rangahau tata nei ka taea tonu te whakamahi i te paura alumina tino pai ki runga i te karāhe photovoltaic me te kore e pā ki te kounga o te karāhe. Ka whakamahia te rauemi mata i ngā āhuatanga o te rahi matūriki iti me te nui ake i te kaha o te mata. Te mātāpono kōwhiringa o te tipu konumohe hauwai:
5.1 Me nui te ihirangi o te waikura konumohe, me nui hoki te waikura konumohe
5.2 Te iti o te whakaritenga ihirangi Fe2O3
5.3 Kāore he parahanga, kāore hoki he kirikiri.
