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钛和硼制取二硼钛的方法，制备出相对纯度大于95％的二硼钛。

"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，二硼铼的硬度与立方结构的氮硼相等，而氮硼是第二硬的。
