ʻO ke anawaena o nā nanowires silicon carbide ka mea maʻamau ma lalo o 500nm, a hiki i ka lōʻihi ke hiki i nā haneli o μm, ʻoi aku ka kiʻekiʻe o ka lākiō ma mua o nā whiskers carbide silicon.

Hoʻoili ʻia nā nanowires silicon carbide i nā ʻano mechanical like ʻole o nā mea nui silicon carbide a loaʻa pū kekahi mau waiwai kūʻokoʻa i nā mea haʻahaʻa haʻahaʻa. ʻO ka manaʻo, ʻo ka modulus o ka Young o hoʻokahi SiCNWs ma kahi o 610~660GPa; hiki i ka ikaika kulou ke piʻi i 53.4GPa, ʻo ia hoʻi ma kahi o ʻelua ʻelua o ko SiC whiskers; ʻoi aku ka ikaika o ka tensile ma mua o 14GPa.

Eia kekahi, ʻoiai ʻo SiC ponoʻī kahi mea semiconductor bandgap indirect, kiʻekiʻe ka neʻe electron. Eia kekahi, ma muli o kona nui nano, ua liʻiliʻi ka hopena o nā nanowires SiC a hiki ke hoʻohana ʻia ma ke ʻano he luminescent; i ka manawa like, hōʻike pū nā SiC-NW i nā hopena quantum a hiki ke hoʻohana ʻia ma ke ʻano he semiconductor catalytic material. Loaʻa i nā uea Nano silicon carbide ka hiki ke hoʻohana ʻia ma ke kahua o ka hoʻokuʻu ʻana o ke kahua, hoʻoikaika a me nā mea paʻakikī, supercapacitors, a me nā mea hoʻoheheʻe hawewe electromagnetic.

Ma ke kahua o ka hoʻokuʻu ʻana o ke kahua, no ka mea, ʻoi aku ka maikaʻi o nā uea nano SiC i ka thermal conductivity, kahi ākea ākea ma mua o 2.3 eV, a me ka hana hoʻokuʻu kahua maikaʻi loa, hiki ke hoʻohana ʻia i loko o nā ʻāpana kaapuni hoʻohui, nā mīkini microelectronic vacuum, etc.
Ua hoʻohana ʻia nā nanowires Silicon carbide e like me nā mea catalyst. Me ka hohonu o ka noiʻi ʻana, hoʻohana ʻia lākou i ka catalysis photochemical. Aia nā hoʻokolohua e hoʻohana ana i nā nanowires silicon carbide e hana i nā hoʻokolohua catalytic rate ma ka acetaldehyde, a e hoʻohālikelike i ka manawa o ka decomposition acetaldehyde me ka hoʻohana ʻana i nā kukuna ultraviolet. Hōʻike ia i nā nanowires silicon carbide i nā waiwai photocatalytic maikaʻi.

No ka mea hiki i ka ʻili o SiC nanowires ke hana i kahi ʻāpana nui o ka papalua-papalua, he maikaʻi loa ka hana mālama ʻana i ka ikehu electrochemical a ua hoʻohana ʻia i nā supercapacitors.
