ʻO Silicon Carbide Ceramics a me Silicon Nitride Ceramics

Nānā nui oʻO Silicon Carbide Ceramics
ʻO ka silikon carbide ceramics he ʻano mea hou o nā mea seramika i hana nui ʻia mai ka pauka carbide silicon ma o ka sintering kiʻekiʻe. He kiʻekiʻe ka paʻakikī o ka silikon carbide, ke kūpaʻa ʻana, ka pale ʻana i ka corrosion, a me ke kūpaʻa wela kiʻekiʻe maikaʻi loa, me nā waiwai mechanical, thermal, a me nā uila. Hiki ke hoʻokaʻawale ʻia nā seramika silicon carbide i compacted sintered silicon carbide ceramics a me ka reaction sintered silicon carbide ceramics ma muli o nā kaʻina hana puhi ʻokoʻa.

ʻO ka ʻike nui o ka Silicon Nitride Ceramics
ʻO ka silikon nitride seramika he mea koʻikoʻi ka hana kiʻekiʻe. Loaʻa iā ia nā waiwai mechanical maikaʻi, ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa corrosion, a me ka conductivity thermal. Ke hoʻohālikelike ʻia me ka silicon carbide ceramics, ʻoi aku ka paʻa o ka silicon nitride ceramics. He kiʻekiʻe loa ka paʻakikī a me ka ikaika o ka silikon nitride ceramics, a no laila ua hoʻohana nui ʻia i ka hana ʻoihana a me ka mīkini pololei ma lalo o ke kiʻekiʻe kiʻekiʻe a me ke kaomi.
ʻO ka ʻokoʻa ma waena o ka silika carbide ceramics a me ka silicon nitride ceramics
1. Nā hale like ʻole
Hoʻokumu ʻia ke ʻano o ka silicon carbide ceramics i ka ikaika hoʻopaʻa ma waena o nā ʻano hua silicon carbide, ʻoiai ʻo ke ʻano o ka silicon nitride ceramics i haku ʻia me nā paʻa naikokona silika i hana ʻia e nā ʻātoma silika a me ka nitrogen. No laila, ʻoi aku ka paʻa o ka silicon nitride ceramics ma mua o ka silicon carbide ceramics.
2. Hoʻohana like ʻole
Hoʻohana pinepine ʻia ka silikoni carbide ceramics i nā kahua mālama wela wela, e like me ka uhi ʻana o ka umu ahi, nā puka makani nānā i ka ʻoihana semiconductor, a me nā kahua hana mīkini. Hoʻohana nui ʻia ka silikon nitride ceramics i ka ʻoki ʻana, ka wili, ka insulation uila, ka pale a me nā māla ʻē aʻe ma lalo o ke kiʻekiʻe kiʻekiʻe a me nā kūlana kiʻekiʻe i ka ʻoihana hana.
3. Hana likeʻole
ʻO ka silikoni carbide ceramics he maikaʻi loa ka wela kiʻekiʻe, ka lole pale, a me ka corrosion-resistant, ʻoiai ʻo ka silicon nitride ceramics ʻaʻole wale nā ​​kiʻekiʻe kiʻekiʻe, ʻaʻahu-kūʻai, a me ka corrosion-kūpono nā waiwai, akā maikaʻi hoʻi ka thermal conductivity a me nā waiwai insulation uila. no laila hiki ke hoʻohana ʻia ma kahi ākea ākea.
I ka pōkole, ʻoiai ʻo ka silicon carbide ceramics a me ka silicon nitride ceramics no nā mea seramika hana kiʻekiʻe, ʻokoʻa ko lākou mau hale, nā noi, a me nā waiwai. Pono nā mea hoʻohana e koho i nā mea kūpono e like me kā lākou pono ponoʻī.
