钨(W)分子式：分子量：CAS号：性质：周期系第Ⅵ副族（铬族）元素。原子序数74。稳定同位素：180，182，183，184，186。原子量183.84。浅灰色金属。密度19.35。熔点3410℃。沸点5930℃。化合价+2、+4和+6。化学性质稳定，只有在红热时才会在空气中氧化或与水蒸气起反应。在常温下不受空气的侵蚀，不与盐酸或硫酸作用，仅微溶于硝酸、氢氟酸和王水。但与硝酸和氢氟酸的混合液共热时则能溶解。主要用于制钨丝和制高速切削钢、特种钢等。也用于制电学和光学仪器。碳化钨（WC或W2C）的硬度接近金刚石，熔点约2900℃。它与钨钢均为重要工业材料。重要的矿物有黑钨矿和白钨矿。将上述钨矿与纯碱共熔得钨酸钠，与盐酸作用成钨酸，煅烧成三氧化钨后用碳或氢还原而制得。
