钨粉

碳化钨粉(WC)是生产硬质合金的主要原料，化学式WC。为黑色六方晶体，有金属光泽，硬度与金刚石相近，为电、热的良好导体。熔点2870℃, 沸点6000℃，相对密度 15.63(18℃)。碳化钨不溶于水、盐酸和硫酸，易溶于硝酸－氢氟酸的混合酸中。纯的碳化钨易碎，若掺入少量钛、钴等金属，就能减少脆性。用作钢材切割工具的碳化钨，常加入碳化钛、碳化钽或它们的混合物，以提高抗爆能力。碳化钨的化学性质稳定<h4 style= "cursor: pointer; " title= "点击可编辑 ">本公司还有其它产品</h4><img alt= " " src= "//i01.c.aliimg.com/img/ibank/2010/512/854/199458215_1247770296.jpg " style= "visibility: visible; width: 724px; height: 129px; " /><img alt= " " height= "116 " src= "//i03.c.aliimg.com/img/ibank/2010/122/854/199458221_1247770296.jpg " style= "visibility: visible; " width= "95 " /><img alt= " " height= "105 " src= "//img11.makepolo.cn/images/formals/img/product/58/23/4_f26adad78313675253bf6e3f243099d1.jpg " style= "visibility: visible; " width= "111 " /><img alt= " " height= "77 " src= "//i01.c.aliimg.com/img/ibank/2010/389/962/137269983_1247770296.jpg " style= "visibility: visible; " width= "100 " /><img alt= " " height= "77 " src= "//i01.c.aliimg.com/img/ibank/2010/200/072/137270002_1247770296.jpg " style= "visibility: visible; " width= "100 " /><img alt= " " height= "77 " src= "//i01.c.aliimg.com/img/ibank/2010/310/072/137270013_1247770296.jpg " style= "visibility: visible; " width= "100 " />
