Ngā kurupae waro silicon

Ngā roera uku silicon carbide (R-SiC) kua whakamātauhia-tauhohengakua puta ake hei wāhanga nui i roto i ngā pūnaha tukatuka wera hou, inā koa te hiranga i roto i te hanga pākahiko lithium, te hanga uku matatau, me te sintering rauemi aukume tino tika. Ka tautuhi anō ēnei roera motuhake i ngā paerewa mahi i roto i ngā oumu ahumahi pāmahana-tiketike mā te aro atu ki ngā wero matua o te pumau wera me te roa o te miihini.

Mahi Wera Kāore i te ōrite

I hangaia kia mahi tonu i te 1450-1600°C – he teitei ake i ngā roera alumina tuku iho – ka mau tonu te tika o ngā āhuatanga o ngā roera R-SiC ahakoa te huringa wera nui. Nā tōna hanganga moroiti ahurei ka taea:

• Te tere o te whakawhiti wera ōrite (±5°C puta noa i te roa o te roera)

• Ka taea te tu atu i ngā huringa ru wera neke atu i te 100 (1400°C ↔ te pāmahana rūma)

• Kore he rerekētanga ngokingoki i ngā pāmahana teitei tonu

Ngā Taupānga Hira kua Whakahoutia

1. Te Hanga Pūhiko Ritiumu

- Te whakarite tika mō te whakakorikori rauemi hiko

- Te whakahaere kore poke o ngā katote NMC/LFP

- Te mahi pumau i roto i ngā āhuarangi whakaiti

2. Te Tukatuka Uku Matatau

- Tautoko kore-whakapiko mō ngā taera whakatakotoranga-rahi (tae atu ki te 1.5×3m)

- Te whakahaere tere ōrite i roto i ngā raina karaihe horoi

- Whakaoti mata kore-tohu (Ra <0.8μm)

3. Te Hanga Rauemi Aukume

- Hurihanga kore-wiri mō te sintering ferrite kua whakaritea

- Te koretake o ngā matū i roto i ngā taiao whai hauwai

Ngā Painga Whakahaere

Te Kaha Utaina: Tautoko i te taumaha 3-5× nui ake mō ia roanga, ki ngā roera whakarewa

Ātete ki te Pirau: Ka mau tonu te tika <0.05mm/m i muri i te 10,000 hāora mahi

Te Whai Hua o te Pūngao: 18-22% te whakaiti i te whakapaunga pūngao o te oumu mā te tohatoha wera kua arotauhia

Hototahi ki ngā Ahumahi Whakawhiti: Ka taea te urutau ki ngā oumu whakawhiti, ngā oumu roera maha-paparanga, me ngā oumu kauhanga ranu

Te Oranga Tonutanga Ōhanga

Ahakoa e hiahiatia ana he haumitanga tīmatanga 30-40% teitei ake i ngā roera tikanga, e whakaatu ana ngā otinga R-SiC:

- 70% te roa ake o ngā wā ratonga (5-7 tau ki te 2-3 tau)

- 90% te āheinga hangarua mā roto i ngā tukanga whakaora wera

- 60% te iti iho o ngā utu tiaki mai i ngā mata ātete-pakurakura

Hoahoa Rite mō te Ao Whānui

Kei roto i ngā roera R-SiC hou:

- Ngā awaawa aroturuki i whakairohia ki te laser mō ngā raina whakaputa aunoa

- Ka taea te whakarite i te porosity mō te urunga motuhake o te hau

- Ngā pūoko wera whakauru mō ngā mahi oumu atamai

Mā ēnei whanaketanga hangarau ka whakanohohia ngā roera karawiti silicon kua whakamātauhia hei wāhanga nui i roto i ngā pūnaha whakamahana ahumahi o te whakatipuranga e whai ake nei, ka taea ai e ngā kaihanga te whakatutuki i te whakahaere pāmahana pakari ake, te ōritetanga hua teitei ake, me ngā rerengamahi whakaputa pumau puta noa i ngā rāngai hangarau teitei maha.

Ko Shandong Zhongpeng Special Ceramics Co., Ltd tētahi o ngā otinga rauemi hou uku silicon carbide nui rawa atu i Haina. Uku hangarau SiC: Ko te pakeke o Moh he 9 (ko te pakeke o Moh hou he 13), he ātete pai ki te horo me te waikura, he ātete pai ki te pakū me te ārai-waikura. Ko te roa o te ora ratonga o te hua SiC he 4 ki te 5 ngā wā roa atu i te rauemi alumina 92%. Ko te MOR o RBSiC he 5 ki te 7 ngā wā i tō SNBSC, ka taea te whakamahi mō ngā āhua uaua ake. He tere te tukanga whakatau utu, ko te tuku e rite ana ki te mea i oatitia, ā, ko te kounga kāore he rite. Ka tohe tonu mātou ki te wero i ā mātou whāinga me te tuku i ō mātou ngākau ki te hapori.
