Ke komo nei i loko o ka honua ʻoihana hou, hiki ke ʻike mau i ke ʻano o kahi ʻano mea kūikawā - ʻaʻole lākou e like me nā metala a ʻaʻole like me ka māmā e like me nā plastics, akā kākoʻo mālie lākou i ka hana o ka ʻoihana hou. ʻO kēia ka ʻohana ceramics ʻoihana, kahi hui o nā mea non-metallic inorganic i kaulana no ko lākou mau waiwai kūikawā.
I. ʻO nā "lālā hōkū" o ka ʻohana ceramics ʻoihana
Ma waena o ka ʻohana ceramics ʻoihana, aia kekahi mau lālā i kū ʻokoʻa: ʻO nā seramika alumina e like me ke kaikuaʻana hilinaʻi, e hilinaʻi ana i ka insulation maikaʻi loa a me ka pale ʻana i ka corrosion, e pāʻani ana i kahi hana koʻikoʻi i nā mea uila a me nā mea hana kemika; ʻO ka silikon nitride ceramics e like me nā mea pāʻani māmā, me ka paʻakikī o nā seramika a me ka paʻakikī o nā metala, e hōʻike ana i ka hana nui i nā bearings a me nā mea hana ʻoki; Ua like ka zirconia ceramics me nā fashionistas, ʻaʻole wale me ka momi like me ka luster akā loaʻa pū kekahi i ka ʻenehana ʻeleʻele o ka "phase transformation toughening", i makemake nui ʻia i nā niho niho a me nā ʻāpana kikoʻī.
II.ʻO nā seramika silikoni: Ke koa holookoa ma ke kahua hana
Ma waena o kēia ʻohana, hiki ke manaʻo ʻia nā ceramics silicon carbide e like me ke koa holoʻokoʻa maoli. ʻO kēia seramika kūikawā i haku ʻia me nā mea silika a me nā kalapona i hana mua ʻia e nā kānaka i ka makahiki 1905 a ua haki mau i nā moʻolelo hana o nā mea ʻenehana. Ua like ia me ka pale kaua daimana, me ka paakiki Mohs a hiki i ka 9.5, lua wale no ke daimana ponoi; Ua like ia me nā mea kaua i hoʻolei ʻia mai nā pōhaku lepo refractory, hiki ke kū i ka 1350 ℃ o ka kuke wela wela.
I loko o ka hale hana metallurgical, hana ʻia nā kilnware silicon carbide ceramics i ke kinai ʻana i nā bilets kila; i loko o nā pipeline kemika, hoʻololi ia i kahi kahu pale corrosion, hoʻonui i ke ola lawelawe o nā pipeline; ma nā laina hana semiconductor, he koho maikaʻi nō hoʻi ia no ka lawe pololei ʻana; ʻOi aku ka kupanaha, ʻo kēia mea koʻikoʻi koʻikoʻi he mea hoʻokele wela maikaʻi loa, e ʻike ai i kona wahi ma ke kahua o ka hoʻoheheʻe wela uila.
III. ʻO ka hoʻololi a me ka hānau hou i lawe ʻia e ka ʻenehana
Ua hāʻawi ka ʻenehana hou i nā seramika silika carbide me ke ola hou. Ma o ka ʻenehana nanomodification, ua hoʻonui ka poʻe ʻepekema i kona paʻakikī; me ka hoʻohana ʻana i ka ʻenehana paʻi 3D, hiki ke hana ʻia nā ʻāpana ʻano paʻakikī e like me nā hana noʻeau. I loko o ka hale hana o kā mākou hui, ke aʻo nei nā ʻenekinia i nā ʻano sintering silicon carbide, me ka hoʻohana ʻana i ka ʻenehana sintering kiʻekiʻe e hoʻokō i nā koi huahana like ʻole o nā mea kūʻai aku a hoʻomaikaʻi mau i ka hana o nā huahana silicon carbide ceramic, e hiki ai iā lākou ke hoʻololi i nā kūlana hana paʻakikī.
Mai ka ʻoihana kuʻuna a hiki i ka ʻenehana ʻokiʻoki, ke kākau nei nā ceramics ʻoihana i kahi moʻolelo hou. Ma ke ʻano he mea lawelawe ʻenehana loea i ka silicon carbide ceramics, ke kūpaʻa mau nei mākou i ka hāʻawi ʻana i nā hoʻonā maʻamau. ʻO ka hana ʻana i nā ʻāpana ʻano kūikawā me nā kikoʻī kūikawā a i ʻole ka hoʻolālā ʻana i nā hoʻonā noi no nā kūlana hana koʻikoʻi, hiki iā mākou ke loaʻa ke kākoʻo ʻoihana ma aneʻi.
