Kiekie Mahahana Hana o Silicon Carbide Crucibles

ʻO nā kīʻaha silika carbideʻike ʻia no kā lākou hana wela kiʻekiʻe maikaʻi loa a hiki iā ia ke kū i nā wela hana kiʻekiʻe loa. ʻO ka mea maʻamau, hiki ke hana me ka palekana a me ka paʻa ʻana o nā crucibles silicon carbide kiʻekiʻe ma ke ʻano wela o 1600°C a 2200°C (2912°F a 3992°F), a hiki i kekahi mau crucibles i hana ʻia a mālama ʻia hiki ke kū i nā mahana a hiki i 2700° C (4952°F).

Ma nā noi kūpono i nā hoʻokolohua kiʻekiʻe-mehana a i ʻole nā ​​​​kaʻina hana e like me ka hoʻoheheʻe metala a me ka sintering seramika, pono e hoʻoholo ʻia ka mahana hana kūikawā o ka silicon carbide crucible e pili ana i nā koi kaʻina hana, nā kūlana ea a me nā waiwai kemika o ka mea. Eia hou, pono e hahai ʻia nā kaʻina hana kūpono no ka pale ʻana i ka crucible mai ka haki ʻana a i ʻole ka pōʻino ma muli o nā loli wikiwiki o ka mahana.

ʻOiai hiki i nā kīʻaha silicon carbide ke kū i nā wela kiʻekiʻe, he mea nui ia e pale aku i ka ʻoi aku o ka nui o ka mahana hana e pale ai i ka pōʻino i ka mea a i ʻole ke ʻano o nā mea haumia. Pono e hahai ʻia nā kaʻina hana hoʻoluʻu kūpono ma hope o ka hoʻohana ʻana i mea e pale ai i ka haki ʻana ke kau ʻia ma luna o nā ʻili anuanu, a pono e mālama pono e pale i ka hopena kino nui i ka wā e hoʻohana ai i mea e pale ai i ka pōʻino.
