Aluminum Oxide Crucible AL2O3 Crucible
hōʻike huahana
ʻO ka alumina oxide crucible i kapa ʻia ʻo corundum crucible, ʻoi aku ka nui o ka alumina ma mua o 95% i kapa ʻia ʻo corundum crucible.ʻO Corundum crucible ka ikaika o ka hoʻoheheʻe ʻana, ke kūpaʻa wela kiʻekiʻe, ka pale ʻana i ka waikawa a me ka alkali, ke anuanu a me ka wela, ke kūpaʻa kino kino.He kūpono ia no kekahi mau mea alkaline nāwaliwali e like me Na2CO3 anhydrous e like me nā mea hoʻoheheʻe flux, akā ʻaʻole no Na2O2, NaOH, a me nā mea ʻē aʻe. ka insulation a me ka ikaika mechanical i ka redox lewa o 1650 ℃ -1700 ℃, me ka wela kiʻekiʻe o 1800 ℃ i ka manawa pōkole.E like me nā kūlana noi, loaʻa nā alumina crucibles i nā ʻano nui a me nā ʻano.
Nā hiʻohiʻona nui
ʻO nā hiʻohiʻona nui o ka alumina ceramic crucible: ke kū ʻana o ka wela ma kahi o 1200 degere, kūpono no K2S207 a me nā mea hoʻoheheʻe waiwai ʻē aʻe.ʻO ka mea maʻamau, ʻaʻole pono e hoʻohana ʻia no ka hoʻoheheʻe ʻana o Na0H, Na202 a me Na2CO3, i ʻole e corrode i ka crucible porcelain.ʻAʻole hiki ke hoʻopili ʻia ke kīʻaha porcelain me ka waika hydrofluoric.
Hiki ke hoʻolapalapa ʻia ka HCl alumina ceramic crucible e hōʻoia i ka maʻemaʻe o ka mea a me ke kūpaʻa wela kiʻekiʻe.He kiʻekiʻe ke kiʻekiʻe o ka mea, ke kūpaʻa oxidation maikaʻi, 400-500 degere kiʻekiʻe ma mua o ka mea graphite, a hiki i 900 degere kiʻekiʻe, lōʻihi ke ola lawelawe.Me ke kūpaʻa wela kiʻekiʻe, ka hoʻonui haʻahaʻa haʻahaʻa haʻahaʻa, ka wela maikaʻi a me ke kūpaʻa haʻalulu a me ke kūpaʻa corrosion maikaʻi.Paʻa ka hana kemika a ʻaʻole i pane me ka metala i hoʻoheheʻe ʻia, e hoʻomaikaʻi ana i ka maʻemaʻe o ka alloy.
(1) Maʻalahi e holoi a mālama maʻemaʻe.ʻO ka glaze o ka ceramic crucible he mālamalama a palupalu, a maʻalahi ke holoi ma hope o ka hoʻohana ʻana.
(2) He kakaikahi loa ka stoma porcelain, a he haʻahaʻa loa ka nui o ka komo ʻana o ka wai.ʻO ka mālama ʻana i ka hopena me ka ceramic crucible a me ka sila paʻa hiki ke pale i ka volatilization, infiltration a me ka hoʻouka ʻana o nā bacteria waho.
(3) Paʻa kemika a me ka lōʻihi.ʻOi aku ka maikaʻi o kēia wahi ma mua o nā huahana metala e like me ke keleawe, ka hao, ka aluminika, a me nā mea ʻē aʻe. ʻelemakule.
(4) Paʻa wela maikaʻi a me ka hoʻololi wela.Loaʻa i ka ceramic crucible ka hana o ka hele ʻana i kahi ʻokoʻa wela, ʻoi aku ka maikaʻi ma mua o ka aniani, he conductor maikaʻi ʻole ia o ka wela, hoʻololi i ka wela, hoʻohana ʻia e hoʻopaʻa i ka wai paila a i ʻole ka hopena wela, ʻaʻole wela loa ka hopena.
Hoʻohana Huahana
Hoʻohana nui ʻia ka alumina, nā mea uila, ka aila, kemika, refractory, ceramics, plastics, textile, pepa, a me ka lāʻau lapaʻau a me nā mea ʻē aʻe he nui ke ʻike ʻia kona kiʻi, he mau waiwai kūikawā o ka alumina a me ka alumini hydroxide.Eia nō naʻe, ʻoi aku ma mua o 90 ka nui o ka alumina i hoʻohana ʻia e like me ka mea maka no ka alumini electrolytic.
I kēia manawa, nui nā ʻano non-alumina no ka hoʻomaʻamaʻa ʻana, ʻoi aku ma mua o 300 mau ʻano, ʻo kēlā me kēia o ia mau mea he maikaʻi ke kino a me nā waiwai kemika, akā ʻoi aku ka kiʻekiʻe o ke kumukūʻai ma mua o ka alumina no ka mālama ʻana.
Ma ke kiʻekiʻe maʻemaʻe ultrafine alumina, no ka laʻana, no kona kiʻekiʻe heheʻe, kiʻekiʻe paʻakikī, kiʻekiʻe ke kū'ē, nā mea mechanical maikaʻi, ke kū'ēʻana i kaʻaʻahu, ka paleʻana i kaʻino, ka wela a me nā mea maikaʻi'ē aʻe 2.Main Featuress, no laila ua hoʻohana nuiʻia i nā mea aniani hoʻokahi. , porcelain kiʻekiʻe, iwi artificial, semiconductor, wili mea, integrated circuit substrate, recording tape filler, catalyst and its carrier, laser materials, cutting tools, etc.
