$Kuʻuna kiʻekiʻe wela corrosion pale SiC Bonded Si3N4 Refractory Brick$

ʻO ka wehewehe pōkole:

ʻO WeiTai Energy Technology Co., Ltd. kahi mea hoʻolako alakaʻi kūikawā i ka wafer a me nā mea hoʻohana semiconductor holomua.Hoʻolaʻa mākou i ka hāʻawi ʻana i nā huahana kiʻekiʻe, hilinaʻi, a me nā mea hou i ka hana semiconductor,ʻoihana photovoltaica me nā kahua ʻē aʻe e pili ana.

Loaʻa i kā mākou laina huahana nā huahana graphite i uhi ʻia ʻo SiC/TaC a me nā huahana seramika, e hoʻopuni ana i nā mea like ʻole e like me ka silicon carbide, silicon nitride, a me ka alumini oxide a me nā mea ʻē aʻe.

Ma keʻano he mea hoʻolako hilinaʻi, hoʻomaopopo mākou i ke koʻikoʻi o nā mea hoʻohana i ka hana hana, a ua kūpaʻa mākou i ka hāʻawiʻana i nā huahana i kūpono i nā kūlana kiʻekiʻe loa e hoʻokō i nā pono o kā mākou mea kūʻai.

E hoʻouna i ka leka uila iā mākou

ʻO ka Silicon nitride i hui pū ʻia me ka silicon carbide kiln he mau hiʻohiʻona o ka ikaika wela kiʻekiʻe, maikaʻi thermal shock resistance, maʻalahi deformation, oxidation resistance, corrosion resistance, maikaʻi thermal conductivity a pēlā aku.

Nā hōʻailona hana nui

Hoʻohana nui ʻia nā huahana i ka huila wili seramika, nā huahana alumini kiʻekiʻe, ka pōlele porcelain aluminika, ka kiln ʻoihana, ka seramika uila, ka porcelain uila uila kiʻekiʻe, nā mea hoʻomaʻemaʻe, ka porcelain i kēlā me kēia lā, nitride alloy a me nā seramics foam a me nā ʻoihana ʻē aʻe.

He 3.13 ka nui o ka pale lole o ka mea Si3N4-SiC i ko ke kila pale lole (Crl5Mo3), a he 1/3 wale no ke kaumaha o ke kila pale lole (Crl5Mo3).

ʻO nā waiwai hoʻemi maikaʻi o ka corrosion resistance o Si3N4-SiC a me ka calcium carbide a me ka alumina i loko o nā hopena like ʻole penei:
