• Te takai hiko me te takai uku

• Ngā hora wera wera mō ngā maramara mana teitei

Ko ngā waka hiko (EV), ngā photovoltaics (PV), ngā pokapū raraunga, me ngā hanganga 5G ngā tino kaiārahi tipu mō ngā rauemi e pā ana ki te SiC.

3. Ngā Uku Matatau me ngā Rauemi Ātete

Nā tōna kaha me tōna ātete ki te wera, ka mahi te paura moroiti SiC hei wāhanga whakapakari i roto i ngā hanganga uku mahi-teitei.

Ko ngā mākete noa ko:

• Ngā taonga me ngā oko tahu oumu

• Ngā pūwero mura

• Ngā wāhanga ātete-mau

• Ngā wāhanga o te tāhū me te rererangi

• Ngā wāhanga peera me te papu

Ko ngā ahumahi pēnei i te whakarewa, te rererangi, me te pūngao e hiahia ana ki ngā rauemi e mau ana te kaha i runga ake i te 1400°C, ā, e ātete ana ki te horo matū—he āhuatanga e hangai ana ki ngā uku SiC.

4. Ngā Whakamahinga Rokiroki Pūhiko, Pūtau Wahie me te Pūngao

Kei te waihangahia e ngā hangarau pūngao ma hou ngā whai wāhitanga hou mōkarāhe siliconpaura iti

Hei tauira:

• Ngā tāpiringa kawe pākahiko

• Ngā rauemi anode hiato

• Ngā uku pūtau wahie pāmahana-tiketike

• Ngā pūnaha whakahaere me te whakawhiti wera

I te tere haere o te whakamahinga o te EV, ka haere tonu te whānui o te hononga i waenga i te SiC taumata-haurua me ngā pūnaha rokiroki pūngao.

5. Te Hanga Tāpiri me ngā Rauemi Whakakotahi

He mahi nui tā te paura moroiti SiC i roto i te hanga tāpiri (AM), inā koa mō te tānga uku 3D me ngā hiato whakarewa.

Ko ngā painga ko:

• Te kaha miihini kua whakarei ake

• Taumaha iti ake me te pakari ake

• Te ātete nui ki te kakahu me te waikura

E whakamahia ana ēnei rauemi mō ngā mahi rererangi, te tiaki whenua, me ngā mahi motuka, he mea nui hoki te mama me te pakari.

6. Ngā Taupānga Mahi Whatu me te Pūwero

He pai ngā āhuatanga whatu o te SiC i roto i ngā roangaru pūwero, e āhei ai te whakamahi i roto i:

• Ngā matapihi IR

• Ngā pūoko me ngā taputapu kite

• Ngā paninga tiaki

E hiahia ana ēnei mākete ki ngā rauemi e kaha ana ki te tu atu i ngā ru wera me ngā hihi o te rangi.

7. Ngā Taupānga Hangarau Taiao me te Matū

Nā te koretake o ngā matū, ka tautokohia hoki e te paura moroiti SiC ngā pūnaha tātari wai ahumahi me ngā pūnaha tukatuka matū.

Hei tauira:

• Ngā kiriuhi tātari uku

• Ngā kaikawe whakakorikori

• Ngā takirere me ngā hiri ātete-waikura
