He aha ka uhi ʻana o ka silicon carbide?

ʻO ka uhi ʻana o ka silikona carbide,ʻike nui ʻia ʻo SiC coating, e pili ana i ke kaʻina hana o ka hoʻopili ʻana i kahi papa o ka silicon carbide ma luna o nā ʻili ma o nā ʻano hana e like me Chemical Vapor Deposition (CVD), Physical Vapor Deposition (PVD), a i ʻole thermal spraying. Hoʻonui kēia uhi keramika silicon carbide i nā waiwai o ka ʻili o nā substrates like ʻole ma ka hāʻawi ʻana i ke kūpaʻa ʻaʻahu kūikawā, ke kūpaʻa wela, a me ka pale ʻana i ka corrosion. Ua kaulana ʻo SiC no kona mau waiwai kino a me nā kemika koʻikoʻi, me kahi kiko heheʻe kiʻekiʻe (ma kahi o 2700 ℃), paʻakikī loa (Mohs scale 9), kūpaʻa maikaʻi loa i ka corrosion a me ka oxidation, a me ka hana ablation kūikawā.

Nā Pōmaikaʻi Koʻikoʻi o ka Uhi ʻana o Silicon Carbide i nā Hana ʻOihana

Ma muli o kēia mau hiʻohiʻona, hoʻohana nui ʻia ka uhi ʻana o ka silicon carbide ma nā kahua e like me ka aerospace, nā lako kaua, a me ka hana semiconductor. Ma nā wahi koʻikoʻi, ʻoi aku hoʻi i loko o ka pae 1800-2000 ℃, hōʻike ka uhi ʻana o SiC i ke kūpaʻa wela kupaianaha a me ke kū'ē ablative, e kūpono ana no nā noi wela kiʻekiʻe. Eia nō naʻe, ʻaʻohe pono o ka silicon carbide wale nō i ka pono o ke ʻano e pono ai no nā noi he nui, no laila hoʻohana ʻia nā ʻano uhi e hoʻohana i kona mau waiwai kū hoʻokahi me ka ʻole o ka hoʻopilikia ʻana i ka ikaika o nā ʻāpana. I ka hana ʻana o ka semiconductor, hāʻawi nā mea i uhi ʻia me ka silicon carbide i ka palekana hilinaʻi a me ka paʻa o ka hana i loko o nā lako i hoʻohana ʻia i nā kaʻina hana MOCVD.

Nā ʻAno Maʻamau no ka Hoʻomākaukau ʻana i ka Uhi ʻana o Silicon Carbide

Ⅰ● Uhi ʻana o ka Silicon Carbide i ka hoʻokahe ʻana o ka mahu kemika (CVD)

Ma kēia ʻano hana, hoʻokumu ʻia nā uhi SiC ma ke kau ʻana i nā substrates i loko o kahi keʻena hopena, kahi e hana ai ka methyltrichlorosilane (MTS) ma ke ʻano he precursor. Ma lalo o nā kūlana i kāohi ʻia—ʻo 950-1300°C a me ke kaomi maikaʻi ʻole—hoʻoheheʻe ʻia ka MTS, a waiho ʻia ka silicon carbide ma luna o ka ʻili. Hōʻoia kēia kaʻina hana uhi CVD SiC i kahi uhi paʻa a like me ka hoʻopili maikaʻi loa, kūpono no nā noi kikoʻī kiʻekiʻe ma nā ʻāpana semiconductor a me aerospace.

ʻElua● Ke ʻAno Hoʻololi Precursor (Polymer Impregnation and Pyrolysis – PIP)

ʻO kekahi ʻano hana uhi ʻaila silicon carbide kūpono ʻo ia ke ʻano hoʻololi mua, kahi e pili ana i ka hoʻoluʻu ʻana i ka laʻana i mālama mua ʻia i loko o kahi hopena precursor ceramic. Ma hope o ka hoʻomaʻemaʻe ʻana i ka pahu impregnation a me ke kaomi ʻana i ka uhi, hoʻomehana ʻia ka laʻana, e alakaʻi ana i ka hoʻokumu ʻana o ka uhi silicon carbide i ka wā e hoʻomaʻalili ai. Makemake ʻia kēia ʻano hana no nā ʻāpana e koi ana i ka mānoanoa like o ka uhi a me ka pale ʻana i ka ʻaʻahu.

Nā Waiwai Kino o ka Uhi ʻana o Silicon Carbide

Hōʻike nā uhi ʻana o ka silicone carbide i nā waiwai e kūpono ai no nā noi ʻoihana koʻikoʻi. ʻO kēia mau waiwai:

Ka Hoʻokele Wela: 120-270 W/m·K
Ka helu o ka hoʻonui wela: 4.3 × 10^^(-6)/K (ma 20~800℃)
Ke kū'ē uila: 10^⁵– 10^⁶Ω·kenimi
Paʻakikī: Mohs unahi 9

Nā noi o ka uhi ʻana o Silicon Carbide

I ka hana semiconductor, pale ka uhi silicon carbide no MOCVD a me nā kaʻina hana wela kiʻekiʻe i nā lako koʻikoʻi, e like me nā reactors a me nā susceptors, ma ka hāʻawi ʻana i ke kūpaʻa wela kiʻekiʻe a me ke kūpaʻa. I ka aerospace a me ka pale kaua, hoʻopili ʻia nā uhi keramika silicon carbide i nā ʻāpana e pono e kū i nā hopena wikiwiki a me nā wahi ʻino. Eia kekahi, hiki ke hoʻohana ʻia ka pena silicon carbide a i ʻole nā ​​​​uhi ma nā mea lapaʻau e pono ai ka lōʻihi ma lalo o nā kaʻina hana sterilization.

No ke aha e koho ai i ka uhi ʻana o Silicon Carbide？

Me ka moʻolelo i hōʻoia ʻia i ka hoʻolōʻihi ʻana i ke ola o nā ʻāpana, hāʻawi nā uhi silicon carbide i ka lōʻihi a me ke kūpaʻa o ka mahana, e hoʻolilo ana iā lākou i mea kūpono no ka hoʻohana lōʻihi. Ma ke koho ʻana i kahi ʻili i uhi ʻia me ka silicon carbide, pōmaikaʻi nā ʻoihana mai ka emi ʻana o nā kumukūʻai mālama, ka hilinaʻi o nā lako, a me ka hoʻomaikaʻi ʻana i ka pono hana.

No ke aha e koho ai iā VET ENERGY?

He mea hana ʻoihana ʻo VET ENERGY a he hale hana o nā huahana uhi silicon carbide ma Kina. ʻO nā huahana uhi SiC nui e komo pū me ka mea hoʻomehana uhi keramika silicon carbide,ʻO ka uhi ʻana o CVD Silicon Carbide MOCVD Susceptor, Ka mea lawe kiʻi MOCVD me ka uhi ʻana o CVD SiC, Nā mea lawe kumu Graphite i uhi ʻia me SiC, ʻO ka Silicon Carbide Coated Graphite Substrate no ka Semiconductor,ʻO ka SiC Coating/Coated Graphite Substrate/Tray no ka Semiconductor, ʻO CVD SiC i uhi ʻia me ke kalapona-kalapona Composite CFC Boat MoldUa kūpaʻa ʻo VET ENERGY i ka hoʻolako ʻana i nā ʻenehana holomua a me nā hoʻonā huahana no ka ʻoihana semiconductor. Ke manaʻolana nei mākou e lilo i hoa hana lōʻihi nou ma Kina.
