ʻenehana hana o ka graphite-silicon carbide crucible

ʻO ka haku mele ʻana of graphite-silicon carbide cruciblesʻO ka hui pū ʻana o nā mea like ʻole, e hāʻawi ana kēlā me kēia i nā waiwai kūʻokoʻa o ka huahana hope. Hoʻokumu ʻia me ka flake graphite, silicon carbide, elemental silicon powder, boron carbide pauda a me ka pālolo, ʻo ka pākēneka kaumaha o kēia mau mea maka he mea koʻikoʻi i ka hoʻoholo ʻana i nā waiwai o ka crucible.

ʻO ke kaʻina hana o ka graphite-silicon carbide crucibles he mau ʻanuʻu meticulous e hōʻoia i ka maikaʻi a me ka pololei o ka huahana hope. Hoʻohui like ʻia nā mea maka e hana i kahi slurry kūpono, a laila e hoʻokomo ʻia i loko o ka mold a kaomi ʻia i ke ʻano me ka hoʻohana ʻana i kahi paʻi isostatic. Hoʻomaloʻo ʻia ka blank hopena a uhi ʻia me ka glaze pale, a laila hoʻoheheʻe ʻia a hoʻoheheʻe ʻia i loko o ke aniani aniani ma o ke kaʻina kī ʻana. A laila nānā ʻia ka huahana i hoʻopau ʻia a manaʻo ʻia ua mākaukau no ka hoʻohana.

ʻO ka mea ʻokoʻa e pili ana i kēia kaʻina hana ʻo kona maʻalahi a me ka hana maikaʻi loa o nā crucibles hopena. ʻO ka crucible he ʻano ʻano like ʻole, kiʻekiʻe kiʻekiʻe, haʻahaʻa porosity, wikiwiki ka thermal conductivity a me ke kūpaʻa corrosion ikaika. ʻO kēia mau hiʻohiʻona he mea kūpono ia no nā ʻano noi like ʻole, ʻoi aku hoʻi i nā ʻoihana kahi e maʻa mau ai ka mahana wela a me nā kemika paʻakikī.

ʻO kahi hiʻohiʻona koʻikoʻi o ke kaʻina hana ʻo ka hoʻohana ʻana i ka pālolo ma ke ʻano he mea paʻa. Hoʻohana ʻia kēia koho i kahi kumu ʻelua no ka mea ʻaʻole ia e hāʻawi wale i ka hana i makemake ʻia o ka crucible akā e hoʻēmi pū i nā hopohopo kaiapuni. Ke hoʻohana nei kēia kaʻina hana i ka pālolo ma ke ʻano he mea hoʻopaʻa e pale aku ai i ka decomposition a me ka hoʻokuʻu ʻana i nā mea ʻino e like me ka phenolic resin a i ʻole ka tar, kahi e hoʻopuka ai i ka uahi a me ka lepo i ka wā o ke kaʻina puhi ahi a hoʻohaumia i ke kaiapuni.

I ka hōʻuluʻulu manaʻo, ʻo ke ʻano o nā mea maka a me ke kaʻina hana o ka graphite silicon carbide crucible e hōʻike ana i ka hoʻohui like ʻana o ka ʻepekema a me ka ʻenehana a me ka ʻike kaiapuni. ʻO nā huahana i loaʻa he hōʻike i ke akamai o nā kaʻina hana hana hou, e hāʻawi ana i nā hopena hilinaʻi a paʻa i nā ʻoihana e koi ana i nā crucibles hana kiʻekiʻe.
