ʻO ka pauka Graphite he nui nā mea hoʻohana, e like me ka molded a refractory crucibles i hana ʻia me ka pauka graphite a me nā huahana pili, e like me nā crucibles, flask, stoppers a me nā nozzles. ʻO ka pauka Graphite he pale ahi, haʻahaʻa haʻahaʻa hoʻonui, kūpaʻa i ka wā i hoʻokomo ʻia a holoi ʻia e ka metala i ke kaʻina o ka hoʻoheheʻe ʻana i ka metala, ka hoʻoheheʻe wela maikaʻi a me ka conductivity thermal maikaʻi loa i ke kiʻekiʻe wela, no laila ua hoʻohana nui ʻia ka pauda graphite a me nā huahana pili i ka kaʻina hana o ka hoʻoheheʻe pololei ʻana i ka metala. ʻO ka mea hoʻoponopono graphite Furuite e hoʻolauna iā ʻoe i nā kikoʻī:
Hana ʻia ka pālolo graphite kuʻuna me ka graphite flake i loaʻa ma mua o 85% kalapona, ʻoi aku ka nui o ka graphite flake ma mua o 100 mesh. I kēia manawa, ʻo ka hoʻomaikaʻi koʻikoʻi o ka ʻenehana hana crucible ma waho o ke ʻano o ka graphite i hoʻohana ʻia, ʻoi aku ka maʻalahi o ka nui a me ka maikaʻi o ka flake; ʻO ka lua, ua hoʻololi ʻia ka pālolo kuʻuna e ka silicon carbide graphite crucible, ka mea i loaʻa me ka hoʻokomo ʻana i ka ʻenehana paʻa mau i ka ʻoihana hana kila.
Hiki ke hoʻohana ʻia ka graphite Furuite i ka pauka graphite me ka hoʻohana ʻana i ka ʻenehana kaomi mau. I loko o ka pālolo graphite crucible, nui flake graphite me 90% kalapona maʻiʻo helu no ma kahi o 45%, oiai i loko o ka silika carbide graphite crucible, ka maʻiʻo o ka nui flake mau mea o ka graphite pauka helu wale no 30%, a me ka kalapona maʻiʻo o ka graphite ua hoemiia i. 80%.
