ʻO ka reaction sintering silicon carbide kahi ala no ka hoʻomākaukau ʻana i nā mea seramika hana kiʻekiʻe. Hoʻopili a paʻi ia i ka pauka silicon carbide me nā kemika ʻē aʻe ma lalo o nā kūlana wela kiʻekiʻe e hana ai i ke kiʻekiʻe kiʻekiʻe, kiʻekiʻe paʻakikī, kiʻekiʻe aʻe a me nā mea kūʻē i ka corrosion.
1. Keʻano hoʻomākaukau. ʻO ke kaʻina hana hoʻomākaukau o ka reactive sintering silicon carbide maʻamau i ʻelua mau ʻanuʻu: pane a me ka sintering. I ka hopena o ka hopena, hoʻopili ka pauka silicon carbide me nā kemika ʻē aʻe i nā wela kiʻekiʻe e hana i nā pūhui me nā wahi hoʻoheheʻe haʻahaʻa, e like me ka alumina, boron nitride a me ka calcium carbonate. Hiki i kēia mau pūhui ke hana e like me nā mea hoʻopili a me nā mea hoʻopihapiha e kōkua i ka hoʻonui ʻana i ka hiki ke hoʻopaʻa a me ka wai o nā pauka silicon carbide ʻoiai e hōʻemi ana i nā pores a me nā hemahema i ka mea. Ma ke kahua sintering, ua hoʻopaʻa ʻia ka huahana hopena i nā wela kiʻekiʻe e hana i kahi mea seramika paʻa. ʻO nā mea e like me ka mahana, ke kaomi a me ka lewa pale e pono e hoʻomalu i ke kaʻina sintering e hōʻoia i ka hana maikaʻi o ka mea. Loaʻa i ka mea silicon carbide ceramic nā hiʻohiʻona o ka paʻakikī kiʻekiʻe, ka ikaika kiʻekiʻe, ke kūpaʻa corrosion kiʻekiʻe a me ke kūpaʻa lole kiʻekiʻe.
2. Waiwai. He nui nā waiwai maikaʻi loa o ka carbide silicon reaction-sintered, e hoʻohana nui ʻia i nā kula he nui. ʻO ka mea mua, ʻoi aku ka paʻakikī o nā mea seramika silicon carbide a hiki ke ʻoki i nā mea paʻakikī e like me ke kila. ʻO ka lua, ʻoi aku ka maikaʻi o ka pale ʻana i ka lole silicon carbide a hiki ke hoʻohana ʻia no ka manawa lōʻihi ma lalo o nā kūlana paʻakikī e like me ke kiʻekiʻe kiʻekiʻe a me ke kiʻekiʻe. Eia kekahi, ʻo ka silicon carbide ceramic materials he kiʻekiʻe corrosion resistance a me ke kiʻekiʻe o ka mahana wela, a hiki ke hoʻohana ʻia no ka manawa lōʻihi i nā wahi corrosive a me nā wela kiʻekiʻe.
3. Nā kahua noi. Hoʻohana ʻia ka carbide silicon reaction-sintered i nā kula he nui. No ka laʻana, i ka ʻoihana hana, hoʻohana nui ʻia nā mea seramika silicon carbide i nā abrasives, nā mea ʻoki a me nā ʻāpana lole. ʻO kona paʻakikī kiʻekiʻe a me ke kūpaʻa ʻaʻahu e pono ai no ka ʻoki, wili a me ka wili
He kūpono no ka poni a me nā ʻano ʻē aʻe. I loko o ka ʻoihana kemika, hiki ke hoʻohana ʻia nā mea seramika silicon carbide e hana i nā kemika e like me ka sulfuric acid a me nā waikawa ikaika e like me ka hydrofluoric acid ma muli o ko lākou kūpaʻa corrosion kiʻekiʻe a me ke kūpaʻa wela kiʻekiʻe. Ma ke kahua o ka aerospace a me ka pale, hiki ke hoʻohana ʻia nā mea seramika silicon carbide e hana i nā pahu missile a me nā mea pale wela no nā mokulele kiʻekiʻe. Eia kekahi, hiki ke hoʻohana ʻia nā mea seramika silicon carbide i loko o ke kahua biomedical o nā hui artificial a me nā mea hana orthopedic orthopedic, no ka mea, loaʻa iā lākou ka biocompatibility maikaʻi a me ke kūpaʻa.
ʻO ka reaction sintering silicon carbide kahi ala no ka hoʻomākaukau ʻana i nā mea seramika hana kiʻekiʻe. Hoʻopili a paʻi ia i ka pauka silicon carbide me nā kemika ʻē aʻe ma lalo o nā kūlana wela kiʻekiʻe e hana ai i ke kiʻekiʻe kiʻekiʻe, kiʻekiʻe paʻakikī, kiʻekiʻe aʻe a me nā mea kūʻē i ka corrosion. He mau waiwai maikaʻi nā Silicon carbide ceramic, e like me ka paʻakikī kiʻekiʻe, ke kūpaʻa lole kiʻekiʻe, ke kūpaʻa corrosion kiʻekiʻe a me ke kūpaʻa wela kiʻekiʻe, no laila ua hoʻohana nui ʻia i nā kula he nui e like me ka hana ʻana, ʻoihana kemika, aerospace a me nā kahua pale a me nā kahua biomedical.
