Ka Kiekie o Silicon Carbide Crucibles ma na hoohana wela kiekie

Kīkoi kalapona kalapona, e like me ka graphite crucible, ʻo ia kekahi o nā ʻano crucibles like ʻole a loaʻa iā ia nā pono hana i hiki ʻole i nā crucibles ʻē aʻe ke hoʻohālikelike. Ke hoʻohana nei i nā mea refractory kiʻekiʻe kiʻekiʻe a me nā ʻōnaehana ʻenehana kiʻekiʻe, ua kūkulu mākou i kahi hanauna hou o nā crucibles carbon-silicon kiʻekiʻe. Loaʻa iā ia nā hiʻohiʻona o ke kiʻekiʻe bulk density, ke kiʻekiʻe o ka mahana wela, ka hoʻoili wela wikiwiki, ka waikawa a me ke kūpaʻa alkali, ka ikaika wela kiʻekiʻe, a me ke kūpaʻa oxidation ikaika. ʻO kona ola lawelawe he ʻekolu manawa ma mua o ka pālolo graphite crucibles. ʻOi aku ka maikaʻi o kēia mau mea hoʻokō i nā kīʻaha kalapona kalapona i kūpono no nā wahi hana wela kiʻekiʻe ma mua o nā crucibles graphite. No laila, i ka metallurgy, ka hoʻolei ʻana, nā mīkini, nā kemika a me nā ʻoihana ʻē aʻe, ua hoʻohana nui ʻia nā crucibles carbon-silicon i ka hoʻoheheʻe ʻana i nā mea hao hao a me nā metala non-ferrous a me kā lākou mau ala, a loaʻa nā pono waiwai maikaʻi.

Aia kekahi mau ʻokoʻa a me nā pilina ma waena o nā crucibles kalapona kalapona a me nā crucibles graphite maʻamau. ʻO ka mea mua, ua like lākou: Hoʻokumu ʻia nā pahu kalapona-silikona ma ke kumu o nā crucibles maʻamau a hoʻohana ʻia e honi i nā metala non-ferrous e like me ke keleawe, aluminika, gula, kālā, ke kēpau, a me ka zinc. ʻO ke ʻano o ka hoʻohana ʻana a me ka mālama ʻana ua like like, no laila e nānā pono i ka makū a me ka hopena i ka wā e mālama ai.

ʻO ka lua, aia ka ʻokoʻa i nā mea i hoʻohana ʻia i ka hana ʻana i nā crucibles silicon carbide, ʻo ia ka nui o nā mea carbide silicon. No laila, kūpaʻa lākou i nā wela kiʻekiʻe a hiki ke kū i nā mahana a hiki i 1860 degere, e ʻae ana i ka hoʻohana mau ʻana i loko o kēia pae wela. ʻO ka carbon silicon crucible a me kāna mau huahana i hana ʻia e ka isostatic pressing he mau pōmaikaʻi koʻikoʻi e like me ke ʻano o ke ʻano like ʻole, ke kiʻekiʻe kiʻekiʻe, ka liʻiliʻi o ka sintering haʻahaʻa, ka haʻahaʻa haʻahaʻa haʻahaʻa, ka hana kiʻekiʻe kiʻekiʻe, ke ʻano paʻakikī, nā huahana slender, nui a pololei ka nui, etc. ʻOi aku ka nui o ke kumukūʻai o ka pahu kalapona kalapona ma mua o ʻekolu mau manawa ma mua o ke kumukūʻai maʻamau, e lilo ia i koho kiʻekiʻe no ka hoʻoheʻe ʻana a me ka hoʻolei ʻana.
