ʻO ka graphite crucible, ʻike ʻia hoʻi ʻo ka molten copper ladle, molten copper, etc., pili i ke ʻano o ka crucible i hana ʻia e ke kī ʻana i ka graphite, ka pālolo, ka silica a me ka wax ma ke ʻano he mea maka. Hoʻohana nui ʻia nā kīʻaha graphite e honi i ke keleawe, ke keleawe, ke gula, ke kālā, ka zinc a me ke kēpau a me nā metala non-ferrous ʻē aʻe a me kā lākou mau ala.
Hana ʻia ʻo Graphite crucible me ka graphite flake maoli ma ke ʻano he kumu kumu a me ka pālolo refractory plastic a i ʻole carbon e like me ka mea hoʻopili. Loaʻa iā ia nā hiʻohiʻona o ka pale wela kiʻekiʻe, ka conductivity thermal ikaika, ke kūpaʻa corrosion maikaʻi a me ke ola lawelawe lōʻihi. I ke kaʻina o ka hoʻohana ʻana i ka wela kiʻekiʻe, he liʻiliʻi ka coefficient o ka hoʻonui ʻana i ka wela, a loaʻa iā ia kahi kūʻē kūʻē i ke anuanu wikiwiki a me ka wela wikiwiki. Loaʻa iā ia ke kūpaʻa corrosion ikaika i ka ʻakika a me ka hopena alkaline, he kūpaʻa kemika maikaʻi loa, a ʻaʻole komo i nā hopena kemika i ka wā o ka hoʻoheheʻe ʻana. ʻO ka paia o loko o ka graphite crucible he maʻalahi, a ʻaʻole maʻalahi ka hoʻoheheʻe ʻana o ka metala i hoʻoheheʻe ʻia a pili i ka paia o loko o ka crucible, no laila ua maikaʻi ka wai metala a me ka castability, a he kūpono ia no ka hoʻolei ʻana i nā ʻano like ʻole. . Ma muli o nā hiʻohiʻona maikaʻi o ka graphite crucible i ʻōlelo ʻia ma luna, ua hoʻohana nui ʻia ia no ka hoʻoheheʻe ʻana i ke kila kila a me ka hoʻoheheʻe ʻana i nā metala non-ferrous a me kā lākou mau ala.
