ʻO ka graphite crucible kahi mea hana hale hana kūikawā i hana ʻia me nā mea graphite. Hoʻohana nui ʻia i ka hoʻoheheʻe ʻana i ka wela, ka hopena kemika, ka mālama wela a me nā kaʻina hana hoʻokolohua ʻē aʻe.
ʻO ka graphite crucible maikaʻi ke kūpaʻa wela kiʻekiʻe a me ke kūpaʻa kemika, hiki ke kū i ka corrosion o nā mea hoʻoheheʻe wela kiʻekiʻe, a he kiʻekiʻe thermal conductivity a me ka ikaika mechanical, kūpono no nā noi keʻena like ʻole. He nui nā pono o ka graphite crucible a ʻo ia kekahi o nā mea hana maʻamau i ka hale hana.
ʻO ka mea mua, ʻo ka mea graphite he maʻemaʻe kiʻekiʻe a me ka haʻahaʻa haʻahaʻa haʻahaʻa, hiki ke hāʻawi i kahi ʻano hoʻokolohua maʻemaʻe maʻemaʻe a pale i ka hopena o nā haumia i nā hopena hoʻokolohua. ʻO ka graphite crucible he kiʻekiʻe loa ke kūpaʻa wela, hiki ke mālama i ka hale i ke kiʻekiʻe o ka wela me ka ʻole o ka deformation, a hiki ke kū i ka ʻinoʻino a me ka hoʻoheheʻe ʻana o nā mea hoʻoheheʻe wela kiʻekiʻe. Eia kekahi, ʻo ka mea graphite he thermal conductivity maikaʻi loa, hiki iā ia ke hana wikiwiki a me ke kaulike i ka wela, e hoʻomaikaʻi ana i ka wikiwiki o ka hopena a me ka pono. Hoʻohana nui ʻia ʻo Graphite crucible i nā ʻano hana kemika, metallurgy, material science a me nā hale hana ʻē aʻe. Hiki ke hoʻohana ʻia i ka hoʻokolohua hoʻoheheʻe wela kiʻekiʻe, hoʻokolohua hoʻokolohua thermal, hoʻokolohua hoʻāhu, hoʻokolohua catalytic a pēlā aku. I ka manawa like, hoʻohana nui ʻia ka graphite crucible i nā mea metala a me nā mea seramika e hoʻoheheʻe ʻia a me ke kaʻina hana wela, e like me ka hoʻoheheʻe ʻana i nā mea hoʻohālike metala, sintered ceramic mea.
Nui nā pōmaikaʻi o ka hoʻohana ʻana i ka graphite crucible. ʻO ka mea mua, hiki i ka haʻahaʻa adsorption waiwai o nā mea graphite ke hōʻemi i ka hāʻawi ʻana i nā hemahema a me ke ana hewa, a hoʻomaikaʻi i ka pololei o ka ʻikepili hoʻokolohua. ʻO ka lua, ʻo ka graphite crucible ka maikaʻi o ka corrosion resistance a hiki ke kū i ka corrosion o nā waikawa like ʻole, alkalis, solvents a me nā mea kemika ʻē aʻe, e hōʻoia ana i ka palekana a me ka hilinaʻi o ka hana hoʻokolohua. Eia kekahi, he lōʻihi ke ola o nā mea graphite a me nā kumukūʻai mālama haʻahaʻa, hana ia i kekahi o nā mea hana hoʻokolohua maʻamau i nā laboratories.
I ka hōʻuluʻulu ʻana, ʻo ka graphite crucible he mea hana keʻena hana ikaika e hiki ai ke hāʻawi i kahi kahua hoʻokolohua paʻa i ka wela kiʻekiʻe a me nā kaiapuni kemika. ʻO kona kūpaʻa wela kiʻekiʻe maikaʻi loa, paʻa kemika a me ka conductivity thermal e hana nui ia i nā kahua hoʻokolohua like ʻole. Inā he mau noi hou aku kāu, e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou a i ʻole e kipa i kā mākou pūnaewele official.
