Ka ʻokoʻa ma waena o ka graphite silicon carbide a me ka pālolo graphite crucibles

ʻO nā kīʻaha graphite silikon carbidea ʻo nā kīʻaha pālolo graphite ʻelua mau moku keʻena hana maʻamau i loaʻa kekahi mau ʻokoʻa nui i nā mea waiwai, nā waiwai, a me nā noi.

Material:

ʻO ka graphite silicon carbide crucible: Hana ʻia me ka graphite silicon carbide material, he kiʻekiʻe ke kūpaʻa wela, ka pale ʻana i ka corrosion a me ka conductivity thermal maikaʻi.
Pālolo graphite crucible: hana maʻamau me ka hui ʻana o ka pālolo a me ka graphite, me ka haʻahaʻa haʻahaʻa graphite maʻiʻo, ka nui o ka hoʻohana ʻana i ka pālolo ma ke ʻano he kumu kumu, a hoʻohui ʻia ka graphite e hoʻomaikaʻi i kona kūpaʻa wela kiʻekiʻe.
Palena wela:

Hiki ke kū i nā wela kiʻekiʻe loa a hiki ke hoʻohana maʻamau i ka pae wela o 1500°C a 2000°C a ʻoi aku paha.
Pālolo graphite crucible: He haʻahaʻa ke kū ʻana o ka mahana, a ʻo ka pae wela hoʻohana maʻamau ʻo 800°C a 1000°C. ʻO ka ʻoi aku o kēia pae wela hiki ke hōʻeha maʻalahi a i ʻole ka hoʻololi ʻana o ka crucible.
ʻO ke kūpaʻa ʻino:

ʻO Graphite silicon carbide crucible: He kiʻekiʻe ke kūpaʻa corrosion a hiki ke pale aku i ka hoʻoheheʻe ʻana o nā mea kemika e like me nā waikawa a me nā alkalis.
Pālolo Graphite Crucible: Ma muli o kona kiʻekiʻe kiʻekiʻe o ka pālolo i hoʻohālikelike ʻia me ka graphite silicon carbide, ʻaʻole liʻiliʻi paha ia i ke kūʻokoʻa i kekahi mau mea ʻino loa.
ʻO ka wela wela:

ʻO Graphite silicon carbide crucible: Loaʻa iā ia ka conductivity thermal maikaʻi a hiki ke hoʻololi koke i ka wela i ka hāpana.
Pālolo graphite crucible: ʻOi aku paha ka ʻino o kona conductivity wela ma mua o ka graphite silicon carbide crucible.
Kumukuai a me ka noi:

ʻO ka graphite silicon carbide crucible: ʻoi aku ka nui o ke kumukūʻai, akā kūpono no nā hoʻokolohua a me nā noi e koi ana i nā wela kiʻekiʻe a me ke kūpaʻa ʻana.
Pālolo graphite crucible: He haʻahaʻa ke kumu kūʻai, kūpono no nā noi keʻena hana maʻamau, nā manawa ʻaʻole i kiʻekiʻe nā koi o ka mahana, a i ʻole ke koʻikoʻi o nā koi kūʻē corrosion.
I ka hōʻuluʻulu manaʻo, graphite silicon carbide crucibles a me ka pālolo graphite crucibles he nui nā ʻokoʻa i loko o nā mea, ke kūpaʻa mahana, ka pale ʻana i ka corrosion, thermal conductivity, a me nā mea ʻē aʻe. Hiki iā ʻoe ke nīnau iā mākou a hāʻawi mākou iā ʻoe i nā lawelawe ʻoihana.
