diboride

The carbothermic method of preparation for titanium diboride with titanium oxide and boron oxide in an arc furnace is studied.

研究了电弧炉碳热还原氧钛和氧制取钛的方法，制备出相对纯度大于95％的钛。

"At low applied forces, the hardness of rhenium diboride is equivalent to cubic boron nitride, the second-hardest material known, Kaner said.

在低用力下，铼的硬度与立方结构的氮相等，而氮是第硬的材料。
