Hoʻohana a me nā ʻano o ka graphite sagger crucible

Hiki ke hoʻohana ʻia ka crucible no ka hoʻomehana ʻana i ka nui o nā kristal. Hiki ke hoʻokaʻawale ʻia ka crucible igraphite crucibleakīʻaha quartz. Loaʻa i ka graphite crucible maikaʻi ka thermal conductivity a me ke kūpaʻa wela kiʻekiʻe; Ma ka hoʻohana wela kiʻekiʻe, liʻiliʻi loa ka coefficient o ka hoʻonui wela. Loaʻa iā ia ke kūpaʻa ikaika i ka wela a me ke anu. He kūpaʻa ia i ka waikawa ikaika a me ka alkali. He kūpono ia no ka hoʻomehana ʻana i nā ʻano wai like ʻole; Ma waho aʻe o ka chemistry, hoʻohana nui ʻia nā crucibles graphite i ka metallurgy, ka hoʻolei ʻana, ka mīkini, ka ʻoihana kemika a me nā keʻena ʻē aʻe; Hana ʻia ka graphite crucible i nā mea graphite maoli, e mālama ana i ka hoʻomehana ahi kūikawā maikaʻi loa o ka graphite. Hoʻohana nui ʻia ka graphite crucible no ka hoʻoheheʻe ʻana i nā metala non-ferrous e like me ke keleawe, aluminika a me ka alloy. Nui nā hiʻohiʻona o ka graphite crucible ponoʻī. Maanei mākou e papa inoa pōkole ai i hoʻokahi a ʻelua paha no ʻoe.
1. E emi ka pollution, no ka mea, hiki ke hoʻohana ʻia ka mana maʻemaʻe e like me ke kinoea maoli a i ʻole ke kinoea liquefied i wahie a emi ʻole ka pollution.
2. Haʻahaʻa ikehu hoʻohana, no ka graphite crucible i kūpono hoʻolālā, kūlana holomua a me ka puke mea. Ma hope o ka hoʻāʻo ʻana, ʻoi aku ka haʻahaʻa o ka hoʻohana ʻana i ka ikehu ma mua o ke ʻano like o ka umu ahi.
Hoʻohana nui ʻia ka umu Resistance high purity graphite crucible no ka hoʻoheheʻe ʻana i ke gula, ke kālā a me nā metala kakaʻikahi.ʻO nā kīʻaha seramikaHoʻohana nui ʻia i nā laboratories a me ka hoʻoheheʻe ʻana o ka platinum, ke gula a me nā metala laha. Hiki ke hoʻohana ʻia ka graphite crucible ma kahi wela kiʻekiʻe o 2000 ℃ ma lalo o ke kūlana o ka ea? E decompose a oxidize ikaika? E hoʻohuehue anei ia? ʻO ka mea nui, ʻo ka carburizing ka mea make. Ma lalo o nā kūlana maʻamau, hiki iā ia ke piʻi i 2000 degere i ka lewa, akā e oxidize wikiwiki ia. Pono ka pilikia o ka carburization metala. I kēia manawa aia kahi pale anti carburizing kūikawā ma ka mākeke, kahi i lohe ʻia he hopena maikaʻi.
