He aha ka pauka tungsten carbide

ʻO ka tungsten carbideʻO ka pauka (WC) ka mea maka nui no ka hana ʻana i ka carbide cemented, me ke ʻano kemika WC.ʻO ka inoa piha ka pauka tungsten carbide.He aniani hexagonal ʻeleʻele me ka ʻulaʻula metala a me ka paʻakikī e like me ke daimana.He mea lawe uila maikaʻi a me ka wela.ʻO ka helu hoʻoheheʻe he 2870 ℃, ʻo ka helu hoʻolapalapa ʻo 6000 ℃, a ʻo ka pili pili he 15.63 (18 ℃).TungstencarbideʻAʻole hiki ke hoʻoheheʻe ʻia i loko o ka wai, hydrochloric acid a me sulfuric acid, akā hiki ke maʻalahi i ka waikawa nitric-hydrofluoric acid i hui ʻia.

ʻO ka tungsten carbideʻO ka pauka ka pauka hina ʻeleʻele a hiki ke hoʻoheheʻe ʻia i loko o nā ʻano carbide, ʻoi aku ka titanium carbide, nona ka solubility kiʻekiʻe e hana i kahi hopena paʻa TiC-WC.ʻO kekahi hui o ka tungsten a me ke kalapona ʻo ia ka tungsten carbide, me kahi ʻano kemika o W2C, kahi helu heheʻe o 2860 ° C, kahi paila o 6000 ° C, a me kahi pānaʻi pili o 17.15.ʻO kona mau waiwai, nā ʻano hoʻomākaukau a me nā hoʻohana ʻana e like me ka pauka tungsten carbide.

Hoʻohana nui ʻia ka pauka tungsten carbide i ka hana ʻana o ka carbide cemented.Intungsten carbide pauda, hoʻokomo ʻia nā ʻātoma kalapona i loko o nā āpau o kametala tungstenka lattice me ka luku ole i ka lattice metala mua, e hana ana i ka hooponopono paa interstitial, no laila, ua kapa ia he hui interstitial (a i ole insertion).
