ʻO nā waiwai silicon carbide sintered-reaksi a me nā hoʻohana nui? Hiki ke kapa ʻia ʻo Silicon carbide ʻo carborundum a i ʻole ke one pale ahi, he hui inorganic, i māhele ʻia i ka silicon carbide ʻōmaʻomaʻo a me ka silicon carbide ʻeleʻele ʻelua. Ua ʻike anei ʻoe i nā waiwai a me nā hoʻohana nui o ka silicon carbide? I kēia lā, e hoʻolauna mākou i nā waiwai a me nā hoʻohana nui o ka silicon carbide.
ʻO ka reactive sintering silicon carbide ka hoʻohana ʻana i ke one quartz, ka calcined petroleum coke (a i ʻole ka lanahu coking), ka slag lāʻau (pono e hoʻohui i ka paʻakai meaʻai no ka hana ʻana o ka silicon carbide ʻōmaʻomaʻo) a me nā mea maka ʻē aʻe, e hoʻomau ana i ka hoʻoheheʻe ʻana i ka mahana kiʻekiʻe ma o ka umu hoʻomehana uila.
Nā waiwai o ka silicon carbide i hoʻopili ʻia e ka hopena:
1. ʻO ke koina hoʻonui wela a me ka hoʻonui wela o ka silicon carbide. Ma ke ʻano he mea refractory, loaʻa i ka piliki carbonized ke kūpaʻa maikaʻi loa i ka haʻalulu. Hōʻike nui ʻia kēia ma kona koina hoʻoili wela ikaika (coefficient hoʻoili wela) a me ke koina hoʻonui wela haʻahaʻa.
2, ke alakaʻi ʻana o ka silicon carbide. He mea semiconductor ka Silicon carbide, ʻokoʻa kona alakaʻi ʻana me ke ʻano a me ka nui o nā haumia i hoʻokomo ʻia i loko o ka crystallization, a aia ke kū'ē ma waena o 10-2-1012Ω·cm. I waena o lākou, he mana nui ko ka alumini, ka nitrogen a me ka boron i ke alakaʻi ʻana o ka silicon carbide, a ʻoi aku ka nui o ka piʻi ʻana o ke alakaʻi ʻana o ka silicon carbide me ka nui o ka alumini.
3. Ke kū'ē'ē o ka silicon carbide. Hoʻololi ke kū'ē'ē o ka silicon carbide me ka loli o ka mahana, akā i loko o kahi pae mahana a ua hoʻohuli'ia nā'ano mahana o ke kū'ē metala. 'Oi aku ka pa'akikī o ka pilina ma waena o ke kū'ē'ē a me ka mahana o ka silicon carbide. Ho'onui'ia ka conductivity o ka silicon carbide i ho'opili'ia me ka pi'i'ana o ka mahana i kahi waiwai, a emi iho ka conductivity ke pi'i hou ka mahana.
Ka hoʻohana ʻana o ka silicon carbide:
1, nā mea pale ʻaʻahu - hoʻohana nui ʻia e hana i ka huila one, ka wili ʻana i ka pepa one, ka pōhaku ʻō, ka huila wili, ka wili ʻana i ka paʻi a me nā huahana photovoltaic i loko o nā pūnaewele photovoltaic, nā pūnaewele photovoltaic a me nā ʻāpana o ka wili ʻana, ka wili ʻana a me ka hoʻopili ʻana.
2, mea refractory kiʻekiʻe-hopena - hiki ke hoʻohana ʻia e like me ka deoxidizer ʻoihana metallurgical a me nā mea kū'ē i ka corrosion, e hana i nā ʻāpana prefabricated kiln wela kiʻekiʻe mau, nā ʻāpana paʻa, a pēlā aku.
3, nā keramika hana - ʻaʻole hiki ke hōʻemi wale i ka nui o ka umu, akā hoʻomaikaʻi pū i ka maikaʻi o nā huahana umu ʻoihana, e hōʻemi i ka manawa pōʻaiapuni, ʻo ia ka mea kūpono ʻole no ka sintering glaze seramika, nā keramika non-oxide kiʻekiʻe kiʻekiʻe e hōʻike ana i ka porcelain sintered.
4, nā metala kakaikahi - nā ʻoihana hao a me ke kila, ke kahua hoʻohuihui ʻoihana metallurgical, loaʻa kahi noi.
5, ʻē aʻe - hoʻohana ʻia e hana i ka uhi radiation mamao-infrared a i ʻole ka silicon carbide plate mamao-infrared radiation maloʻo.
Ma muli o nā waiwai kemika organik maʻemaʻe, ka coefficient hoʻoili wela kiʻekiʻe, ka coefficient hoʻonui linear liʻiliʻi, ke kūpaʻa maikaʻi o ka ʻaʻahu, me nā mea kūpaʻa ʻaʻahu, aia kekahi mau hoʻohana nui ʻē aʻe, e like me: me kahi kaʻina hana hou i ka pauka silicon carbide glue i loko o ka impeller centrifugal a i ʻole ke kino cylinder, hiki ke hoʻomaikaʻi i ke kūpaʻa ʻaʻahu a hoʻonui i ke ola lawelawe o 1 a 2 mau manawa; Hoʻohana ʻia e hana i nā mea refractory kiʻekiʻe, ke kūpaʻa haʻalulu wela kiʻekiʻe, ka liʻiliʻi, ke kaumaha māmā a me ka ikaika kiʻekiʻe, ʻike maopopo ʻia ka hopena palekana kaiapuni a me ka mālama ikehu. ʻO ka silicon carbide haʻahaʻa (aia ma kahi o 85% SiC) he mea deoxidizing maikaʻi, hiki ke hoʻohana ʻia e hoʻolalelale i ka wikiwiki o ka hana hao, a he mea kūpono ia no ka hoʻoponopono ʻana i ka haku mele a me ka hoʻomaikaʻi ʻana i ke ʻano o ke kila. Eia kekahi, hoʻohana ʻia ka silicon carbide e hana i nā mea hoʻomehana uila he nui silicon molybdenum rod.
