Nā hiʻohiʻona huahana SiC
ʻO ka wela kiʻekiʻe a me ka corrosion kū'ē, hoʻomaikaʻi i ka maikaʻi o ka wafer a me ka huahana
ʻO ka SiC e pili ana i ka carbide silika.Hana ʻia ʻo Silicon carbide (SiC) i ke one quartz, coke a me nā mea ʻē aʻe ma o ka hoʻoheheʻe ʻana o ka umu wela.He ʻelua ʻano ʻano ʻano hana ʻoihana ʻoihana o ka silicon carbide, ʻeleʻele silicon carbide a me ka ʻōmaʻomaʻo silicon carbide.ʻO lāua ʻelua he aniani hexagonal, ʻo ka gravity kikoʻī o 3.21g / cm3, micro hardness o 2840 ~ 3320kg / mm2.
Ma ka liʻiliʻi he 70 mau ʻano o ka crystalline silicon carbide, ma muli o kona haʻahaʻa haʻahaʻa 3.21g/cm3 a me ka ikaika wela kiʻekiʻe, kūpono ia no nā bearings a i ʻole nā mea wela wela wela.ʻAʻole hiki ke loaʻa i kekahi kaomi, a he haʻahaʻa haʻahaʻa haʻahaʻa.
I ka manawa like, nui ka poʻe i hoʻāʻo e hoʻololi i ka silikoni me ka silicon carbide ma muli o ko lākou kiʻekiʻe thermal conductivity, kiʻekiʻe kiʻekiʻe ʻoki uila ikaika a me ke kiʻekiʻe kiʻekiʻe o kēia manawa.I kēia mau lā, i ka hoʻohana ʻana i nā mea mana kiʻekiʻe semiconductor.ʻO kaʻoiaʻiʻo,ʻo ka silicon carbide substrate i ka thermal conductivity,ʻoi aku ma mua o 10 mau manawa kiʻekiʻe ma mua o ka sapphire substrate, no laila,ʻo ka hoʻohanaʻana i nā mea LED silicon carbide substrate, me ka conductivity maikaʻi a me ka thermal conductivity, pili pono i ka hanaʻana o ka LED kiʻekiʻe.
