vanadium silicide, VSi2

Aniani prismatic mea hao. ʻO 4.42 ka nui o ka nui. ʻAʻole hiki ke hoʻoheheʻe ʻia i loko o ka wai col a me ka wai wela, hiki ke hoʻoheheʻe ʻia i ka waikawa hydrofluoric, hiki ʻole i ka etanol, ka ether a me ka waikawa. Nā hana: e like me ke kime Ka lākiō o ka vanadium pentoxide i ka silikone hana ma 1200 ℃, a i ʻole e like me ka metala Vanadium hiki ke kiʻi ʻia e ka hopena o vanadium me ka silikone i ke kiʻekiʻe wela.

Hoʻohālikelike Nine VSi2. ke kaulike mole 107.11。 Ke aniani prismatic mea hao. ʻO 4.42 ka nui o ka nui. ʻAʻole hiki ke hoʻoheheʻe ʻia i loko o ka wai anuanu a me ka wai wela, hiki ke hoʻoheheʻe ʻia i ka waikawa hydrofluoric, hiki ʻole i ka etanol, ka ether a me ka waikawa. Nā hana: e like me ke kime Ka lākiō o ka vanadium pentoxide i nā siliconreact ma 1200 ℃, a i ʻole e kūlike i ka metala Vanadium hiki ke kiʻi ʻia e ka hopena o vanadium me ka silikone i ke kiʻekiʻe wela. Noi: hoʻohana ʻia no ke kūpaʻa ʻakika a me ke kūpaʻa ahi
ʻEpekema Mea Pono.

1. Hoʻomākaukau o nā kiʻi ʻoniʻoni vanadium silicide. ʻO nā silicides lahilahi me nā waiwai maikaʻi hiki ke hoʻopili pono ʻia e ka implantation o nā ion metala vanadium me ke kiʻekiʻena kiʻekiʻe. Me ka hoʻonui ʻana o ka mānoanoa o ka kaola, ulu ka pae silikala vanadium, a hāʻule maopopo ka pale pale Rs o ka silicide lahilahi. Ke 25 μ A / cm2 ka nui o ke kaola, hiki ka RS i ka palena iki o 22 ψ, e hōʻike ana ua hana ʻia ka silicide mau. Ua hōʻike ʻo X-ray diffraction analysis i ʻehā mau ʻano o ka vanadium silicides, me V3Si, V5Si3, V3Si5 a me VSi2, i hana ʻia i ka papa i hoʻokomo ʻia. Ma hope o ka hoʻopili ʻāina ʻana, hoʻoliʻiliʻi ka RS, hiki ke hoʻoliʻiliʻi ka liʻiliʻi loa i 9 ψ, a hiki i ka resistivity hiki ke like me 72 μ ψ m, e hōʻike ana ua hoʻomaikaʻi hou ʻia ka maikaʻi o ka vanadium silicide lahilahi. Ma hope o ke kiʻekiʻena kiola kukuna a me ka hoʻopili ʻana, ulu aʻe ka ʻāpana silikala vanadium. Hoʻopiʻi ke kiʻekiʻena kukuna a me ka annealing kiʻekiʻe o ka mahana (1200 ℃) stil.

2. ʻO Vanadium silicide kahi ʻano o ke kani ʻana o ka mea pālolo. ʻO ka papa o ka papa me ka waiwai e komo ana i ke kani ua uhi ʻia ma ka ʻili o ka papa o lalo.
