diboride

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

研究了电热还原氧化钛和氧化硼制取二硼化钛的方法，制备出相对纯度大于95％的二硼化钛。

"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，二硼化铼的硬度与立方结构的氮化硼相等，而氮化硼是第二硬的材料。
