Nā Kahua Noi

1. ʻOihana keramika

Hoʻohana nui ʻia nā kaola Silicon carbide (SiC) i loko o nā umu hana keramika, ʻo ia hoʻi noka lawe ʻana i ka ukana, ke kākoʻo, a me ka hoʻoili wela.

Nā keramika hoʻohana i kēlā me kēia lānā kīʻaha, nā pā, nā kīʻaha, a me nā porcelain hale ʻē aʻe i loko o nā umu tunnel a me nā umu roller.
Nā keramika hoʻomaʻemaʻe: nā lua, nā poho holoi, a me nā huahana nui ʻē aʻe e pono ai ka hiki ke halihali ikaika i ka wā e puhi ana i ka mahana kiʻekiʻe no ka manawa lōʻihi.
Ke kūkulu ʻana i nā keramika: nā tile papahele, nā tile paia, a me nā papa keramika nui, kahi e hōʻoia ai nā kaola SiC i ke kākoʻo paʻa a me ka hoʻomehana like.
Nā keramika ʻenehana/kūkulu: e like me nā keramika alumina a silicon nitride paha, ka mea e pono ai nā mahana puhi kiʻekiʻe loa a me nā pōʻaiapuni lōʻihi, e hana ana i ke ola lōʻihi o nā kukuna SiC he mea nui.

2. ʻOihana Aniani

Nā umu hoʻoheheʻe aniani: nā ʻōnaehana kākoʻo no nā ʻōmole, nā aniani, a me ke aniani pālahalaha i ka wā e hoʻomehana ai.
Ke hoʻoheheʻe ʻana i ke anianiMa ka hana aniani kūikawā (aniani optical, aniani hōʻike, a me nā mea ʻē aʻe), hōʻoia nā kukuna SiC i ke kūpaʻa o ka dimensional a me ka hoʻoili wela like.

Nā Pōmaikaʻiʻaʻole e hoʻololi ʻia ke ʻano, ka hoʻoili wela wikiwiki, a me ka hoʻemi ʻana i nā hemahema huahana i hoʻokumu ʻia e ke kaumaha like ʻole.

3. ʻOihana Metallurgy a me ka Pauka

Hoʻoheheʻe ʻana i ka pauka metallurgy: nā ʻāpana kūkulu mai ka hao, ke kila kila, a me nā pauka metala ʻē aʻe.
Nā mea makenekanā mākēneki ferrite, i hoʻā ʻia ma 1200–1400°C, e koi ana i nā kukuna me ke kūpaʻa haʻalulu wela maikaʻi loa a me ke ola lawelawe lōʻihi.
Nā mea honua laha ʻole: ke kālua ʻana i nā oxides honua laha ʻole a i ʻole carbonates, pinepine i loko o nā lewa umu paʻakikī.

ʻOi aku ka maikaʻi o nā kaola SiCi ke kū'ē'ana i ka oxidation a me ka corrosion, e kūpono ana iā lākou no nā'ano metallurgical pa'akikī.

4. Nā Mea Kemika a me ka Ikehu Hou

Ka hoʻoheheʻe ʻana o ka mea hoʻoulunā zeolites, nā sieve molekala, a me nā mea hoʻouluulu petroleum i hoʻokuʻu ʻia i loko o nā umu kemika wela kiʻekiʻe.
Nā mea ikehu hou:
- Nā mea hana cathode pākahiko lithium (NCM, LFP) sintering.
- Ka ikehu hydrogen a me ke ahi ʻana i nā mea huna wahie.

Nā Pōmaikaʻi: hoʻemi ʻia ka hoʻohana ʻana i ka ikehu, lōʻihi ke ola lawelawe, a hoʻomaikaʻi ʻia ke kūlike o ka huahana.
