3. Eu₂O₃, Terbium Oxide (Tb₄O₇)
- Kaupapa:
- Ngā āhuatanga hihiko: e whakamahia ana mō te karāhe hihiko (pērā i ngā mata whakakaha hihi-X, me ngā taputapu whakaatu).
4. Te waikura o te rānamu (La₂O₃), te waikura o te iutrium (Y₂O₃)
- Kaupapa:
- Karāhe taupū whakaata teitei: Whakanuia te taupū whakaata o te karāhe whatu (pērā i ngā karāhe kāmera me ngā karu hiko).
- Karāhe ātete pāmahana teitei: He ātete wera me te pumau matū kua whakarei ake (taonga taiwhanga, muka whatu).
2. Ngā Pūhui Konganuku Onge
He maha ngā wā ka whakamahia ngā konganuku onge ki te karāhe mō ngā paninga mahi motuhake, mō te whakapai ake rānei i te mahi:
1. Indium Tin Oxide (ITO, In₂O₃-SnO₂)
- Kaupapa:
- Paninga ara iahiko: He kiriata ara iahiko mārama e whakamahia ana mō ngā mata pā me ngā whakaaturanga karaihe wai (LCD).
2. Te waikura germanium (GeO₂)
- Kaupapa:
- Karāhe Tuku Pūwero: Whakamahia i roto i ngā pūrere whakaahua wera me ngā taputapu whatu pūwero.
- Muka taupū whakaata teitei: Ka whakapai ake i te mahi whakawhitiwhiti muka whatu.
3. Waikura Kariuma (Ga₂O₃)
- Kaupapa:
- Te mimiti mārama kikorangi: e whakamahia ana i roto i ngā tātari, i ngā mōhiti whatu motuhake rānei.
3. Ngā Pūhui Whakarewa Iti
Ko ngā konganuku iti e pā ana ki ngā konganuku he iti te hanga engari he nui te uara ahumahi, e whakamahia ana mō te tae, mō te whakatikatika rānei i te mahi:
1. Waikura kobalta (CoO/Co₃O₄)
- Kaupapa:
- Tae kikorangi: e whakamahia ana i roto i te karāhe toi, me ngā tātari (pērā i te karāhe hapaira).
2. Waikura Nikara (NiO)
- Kaupapa:
- Tae hina/papura: Ka whakarerekē i te tae o te karāhe, ā, ka taea hoki te whakamahi mō te karāhe whakahaere wera (ka mimiti i ngā roangaru motuhake).
3. Te Selenium (Se) me te waikura selenium (SeO₂)
- Kaupapa:
- Tae whero: Karāhe rupi (kua konatunatua ki te cadmium sulfide).
- Whakakore Tae: Ka whakakore i te tae kakariki i puta mai i ngā poke rino.
4. Waikura Ritiumu (Li₂O)
- Kaupapa:
- Te iti o te ira rewa: Te whakapai ake i te rere o te karāhe (pērā i te karāhe motuhake, te karāhe whatu).
4. Ētahi atu pūhui mahi
1. Waikura titanium (TiO₂)
- Kaupapa:
- He taupū whakaata teitei: e whakamahia ana mō te karāhe whatu me ngā paninga karāhe horoi-ake.
- Parenga UV: Karāhe hanga whare me te karāhe motuka.
2. Waikura vanadium (V₂O₅)
- Kaupapa:
- Karāhe whakamahana-ira: ka whakarite i te whakawhiti mārama i te huringa o te pāmahana (matapihi atamai).
**Whakarāpopoto**
- Ko ngā matū whenua onge te mea nui rawa atu mō te arotautanga o ngā āhuatanga whatu (pēnei i te tae, te hihi kanapa, me te taupū whakaata teitei).
- Ko ngā konganuku onge (pērā i te indium, me te germanium) e whakamahia ana i ngā mara hangarau teitei (ngā paninga kawe hiko, te karāhe infrared).
- Ko ngā konganuku iti (Koparata, Nikara, Hēniuma) e arotahi ana ki te whakahaere tae me te whakakore i te poke.
Mā te whakamahinga o ēnei matū ka taea e te karāhe te whai i ngā mahi rerekē i roto i ngā mara pērā i te hoahoanga, te hikohiko, te whatu, me te toi.
