ʻO ka moku kristal Silicon Carbide i hoʻopili hou ʻia no ka ʻoihana Semiconductor

Nā waiwai o ka carbide silicon i hoʻopili hou ʻia

ʻO ka silicon carbide i hoʻopili hou ʻia (R-SiC) kahi mea hana kiʻekiʻe me ka paʻakikī ʻelua wale nō i ka daimana, i hoʻokumu ʻia ma kahi mahana kiʻekiʻe ma luna o 2000 ℃. Mālama ia i nā waiwai maikaʻi loa o SiC, e like me ka ikaika wela kiʻekiʻe, ke kūpaʻa ikaika i ka pala, ke kūpaʻa oxidation maikaʻi loa, ke kūpaʻa haʻalulu wela maikaʻi a pēlā aku.

● Nā waiwai mechanical maikaʻi loa. ʻOi aku ka ikaika a me ke kūpaʻa o ka silicon carbide i hoʻopili hou ʻia ma mua o ke kalapona fiber, kū'ē i ka hopena kiʻekiʻe, hiki ke pāʻani i kahi hana maikaʻi i nā wahi mahana koʻikoʻi, hiki ke pāʻani i kahi hana counterbalance maikaʻi aʻe i nā kūlana like ʻole. Eia kekahi, he maʻalahi hoʻi kona a ʻaʻole maʻalahi e hōʻino ʻia e ke kīkoʻo ʻana a me ke kūlou ʻana, kahi e hoʻomaikaʻi nui ai i kāna hana.

● Ke kūpaʻa kiʻekiʻe i ka pala. Loaʻa i ka silicon carbide i hoʻopili hou ʻia ke kūpaʻa kiʻekiʻe i ka pala i nā ʻano media like ʻole, hiki ke pale i ka ʻino ʻana o nā ʻano media corrosive like ʻole, hiki ke mālama i kona mau waiwai mechanical no ka manawa lōʻihi, he pipili ikaika, no laila he ola lawelawe lōʻihi. Eia kekahi, he kūpaʻa maikaʻi hoʻi kona, hiki ke hoʻololi i kahi ākea o nā loli mahana, hoʻomaikaʻi i kāna hopena noi.

● ʻAʻole emi ka sintering. No ka mea, ʻaʻole emi ka hana sintering, ʻaʻohe koʻikoʻi koena e hoʻoulu ai i ka deformation a i ʻole ka haki ʻana o ka huahana, a hiki ke hoʻomākaukau ʻia nā ʻāpana me nā ʻano paʻakikī a me ke kiko kiʻekiʻe.
