ʻO ke kīʻaha graphite silicon carbide he ipu ʻano kīʻaha.Ke loaʻa nā mea paʻa i ka wela ma luna o ke ahi kiʻekiʻe, pono kahi kīʻaha no ka mea hiki iā ia ke pale i nā wela kiʻekiʻe ma mua o nā mea aniani.ʻO nā mea nui o ka silicon carbide graphite crucible he graphite flake maoli a me ka binder, a he mea hoʻoheheʻe ʻole a me ka hoʻolei ʻana.Eia nō naʻe, he mea maʻalahi loa ka oxidize ke hoʻohana ʻia i kahi wela kiʻekiʻe a me ka ea oxidizing ikaika, no laila e pale ʻia ka ea oxidizing ikaika i ka hāʻawi ʻana i nā kumu wela like ʻole, i ʻole e hoʻemi ʻia kona ola lawelawe.No ke aha mākou e hoʻohana ai i nā crucibles graphite?E nānā kākou i nā pono o nā crucibles graphite.

ʻO nā mea maikaʻi o ka silicon carbide graphite crucible:

1. ʻOi aku ka maikaʻi o ke kūʻē ʻana, ke kūʻē i ka dissolution a me ka oxidation - 5-10 mau manawa i ka maikaʻi o nā crucibles graphite maʻamau.

2. Hoʻopōkole i ka manawa hoʻoheheʻe, ka hoʻoili wela maikaʻi, ka conductivity thermal kiʻekiʻe, ka mālama ʻana i ka ikehu-e mālama ʻo ia i ka 2 / 5-1 / 3 o ka ikehu.

3. ʻO ke ola lōʻihi - Inā hoʻohana ʻoe ia mea e like me nā koi o kā mākou hui, hiki i kā mākou hui ke hōʻoia i ka maikaʻi no 6 mau mahina mai ka lā i hoʻohana ʻia.Inā hōʻoia ʻia ʻo ia kaʻu pilikia o ka maikaʻi o ka huahana, hiki ke hoʻololi ʻia me ka manuahi a i ʻole ka hoʻemi ʻana.

4. E hoʻonui i ka maikaʻi-e hoʻemi i ka manawa a me ke kumukūʻai o ka downtime.

Silicon carbide graphite crucible ʻo ia ka hoʻohui ʻana i nā ʻike like ʻole o nā ʻāpana silika carbide i loko o ka mea maka o ka graphite crucible, e like me 50% maʻiʻo, 24% maʻiʻo, a me nā mea like ʻole ʻē aʻe, ʻoiaʻiʻo, hiki ke hoʻopili ʻia nā crucibles Graphite i loaʻa nā ʻano like ʻole o ka silicon carbide. e like me nā koi like ʻole o nā mea kūʻai aku.ʻO nā mea i luna aʻe nā mea maikaʻi o ka silicon carbide graphite crucible.
