Kuʻi ʻia ʻo Tungsten (W) Crucible

ʻO ka helu heheʻe o ka tungsten he kiʻekiʻe e like me 3410 ° C.No laila, hoʻohana nui ʻia nā kīʻaha tungsten e like me nā ipu kumu i nā umu ʻoihana e like me ka sapphire single crystal growth furnaces, quartz glass melting furnaces, a me nā kapuahi hoʻoheheʻe honua.ʻOi aku ka maʻamau o ka mahana hana ma luna o 2000 ° C.

No ka sapphire single crystal growth furnaces, tungsten crucibles me ka maemae kiʻekiʻe, kiʻekiʻe kiʻekiʻe, ʻaʻohe māwae o loko, nā ana kikoʻī, a me nā paia ʻoluʻolu o loko a me waho hiki ke hoʻomaikaʻi nui i ka helu kūleʻa o nā kristal hua i ka ulu ʻana o ka kristal sapphire.He mea koʻikoʻi ka tungsten crucible kiʻekiʻe i ka hoʻomalu ʻana i ka maikaʻi o ka huki ʻana o ka kristal, decrystallization pili i ka ipuhao, a me ke ola lawelawe.

Hoʻopili ʻia kā mākou tungsten crucibles i ke ʻano, a laila sintered i nā wela kiʻekiʻe e hana i kahi ʻano paʻa, a hope loa i hana ʻia e hana i nā crucibles tungsten me ka ikaika maikaʻi, ke kū ʻana o ka wela, a me ke kūpaʻa kemika.

'Ōlelo Aʻo: I ka wā e hoʻohana ai i ka tungsten crucible sintered, pono e mālama ʻia e pale i ka hoʻololi wikiwiki ʻana o ka mahana e pale aku ai i ka haki ʻana i ka tungsten crucible sintered.Eia kekahi, pono e mālama ʻia e pale aku i ka hoʻopili ʻana me nā mea oxidizing ikaika e pale aku i ka hopena o ke ola lawelawe o ka tungsten crucible sintered.
