Nā ʻokoʻa ma waena o nā Crucibles Silicon Carbide a me nā Crucibles Graphite

ʻO nā kīʻaha silika carbidea me ka graphite crucibles i hoʻohana mau ʻia i nā ipu wela kiʻekiʻe ma nā hale hana a me nā ʻoihana ʻoihana.Hōʻike lākou i nā ʻokoʻa koʻikoʻi i nā ʻano mea, ke ola, ke kumu kūʻai, nā pae kūpono, a me ka hana.Eia kahi hoʻohālikelike kikoʻī e kōkua i ke koho ʻana i ka crucible kūpono loa no nā pono kikoʻī:

1. Nā ʻano mea:

• ʻO Silicon Carbide Crucibles: Hana maʻamau mai nā mea carbide silicon, hāʻawi kēia mau crucibles i ke kūpaʻa kiʻekiʻe kiʻekiʻe a me ka pale ʻana i ka corrosion.Ua kūpono lākou no nā kaʻina hana e like me ka sintering, ka mālama wela, a me ka ulu aniani o nā metala a me nā seramika.
• ʻO Graphite Crucibles: Hana mua ʻia mai ka graphite flake maoli, i ʻike ʻia ʻo graphite clay crucibles, ʻike lākou i nā noi i ka mālama wela a me ka ulu aniani o nā mea metala a me nā mea ʻole.

2. Ke ola ana:

• Nā Kuʻi Kilika: E pili ana i nā kīʻaha kalapona silika, ʻoi aku ka lōʻihi o ke ola ʻana o nā kuʻi graphite, ma ke ʻano maʻamau mai ʻekolu a ʻelima mau manawa o ko nā kīʻaha silika carbide.

3. Kumukuai:

• ʻO Silicon Carbide Crucibles: Ma muli o nā kaʻina hana a me nā kumukūʻai waiwai, ʻoi aku ke kumu kūʻai o nā crucibles silicon carbide i hoʻohālikelike ʻia me nā crucibles graphite.Eia nō naʻe, i kekahi mau noi, hiki i kā lākou hana kiʻekiʻe ke hōʻoia i ka ʻokoʻa kumukūʻai.

4. Nā pae kūpono:

• Silicon Carbide Crucibles: Ma waho aʻe o ka kūpono no ka hoʻoili ʻana i nā metala a me nā seramika, pili pū nā silicon carbide crucibles i nā ʻoihana uila a me optoelectronics.
• ʻO Graphite Crucibles: He kūpono no ka nui o nā mea metala a me nā mea non-metallic i ka mālama wela a me nā kaʻina ulu kristal.

5. Nā ʻokoʻa hana:

• Nā Kuʻi Graphite: Me ka mānoanoa ma kahi o 1.3 kg/cm², ka ʻokoʻa wela o loko a me waho ma kahi o 35 degere, a me ke kūpaʻa maikaʻi ʻole i ka ʻakika a me ka palaka alkali, ʻaʻole hiki i nā crucibles graphite ke hāʻawi i ka mālama ʻana i ka ikehu e like me nā crucibles carbide silicon.
• Silicon Carbide Crucibles: Me ka nui mai ka 1.7 a i ka 26 kg / mm², kahi ʻokoʻa o loko a me waho o 2-5 degere, a me ke kūpaʻa maikaʻi ʻana i ka waikawa a me ka alkali corrosion, hāʻawi nā silicon carbide crucibles i ka mālama ʻana i ka ikehu ma kahi o 50%.

Ka hopena:

I ke koho ʻana ma waena o ka silicon carbide a me ka graphite crucibles, pono nā mea noiʻi e noʻonoʻo i nā koi hoʻokolohua, nā palena kālā, a me ka hana i makemake ʻia.ʻOi aku ka maikaʻi o nā crucibles Silicon carbide i nā ʻāina wela a me nā corrosive, aʻo nā crucibles graphite e hāʻawi i nā pōmaikaʻi ma ke ʻano o ke kumukūʻai a me ka hoʻohana ākea.Ma ka hoʻomaopopo ʻana i kēia mau ʻokoʻa, hiki i nā mea noiʻi ke hoʻoholo i ka ʻike e hōʻoia i nā hopena maikaʻi loa i kā lākou hoʻokolohua.
