性狀
為黑色六方晶系結(jié)晶。熔點(diǎn)2870℃±50℃。沸點(diǎn)6000℃。溶于硝酸與氫氟酸的混酸和王水中,不溶于冷水。相對(duì)密度d1815.63。耐酸性強(qiáng)。硬度高。彈性模量大。
所屬類(lèi)別
無(wú)機(jī)化工產(chǎn)品: 無(wú)機(jī)鹽: Cp鉬、鈦、鎢、釩、鋯
用途與作用
用于生產(chǎn)各種合金。
合成工藝與制法
鎢粉碳化法將三氧化鎢加氫還原制得鎢粉(平均粒度3~5μm)。再把鎢粉和炭黑按等摩爾比混合(用球磨機(jī)干混約10h),在101.325 Mpa左右的壓力下加壓成型。將該加壓成型粉末放進(jìn)石墨盤(pán)或坩堝內(nèi),用石墨電阻爐或感應(yīng)電爐在氫氣流中(使用露點(diǎn)為-35℃的純氫)加熱至1550~1650℃,使之滲碳,則生成碳化鎢成品。
