| Rhenium diboride ReB2 |
| A synthetic superhard material of hardness comparable to diamond. The production method of this material does not involve high pressures as with other hard synthetic materials, such as cubic boron nitride, which makes production cheap. The compound is formed from a mixture of rhenium, noted for its resistance to high pressure, and boron, which forms short, strong covalent bonds with rhenium. The resulting material is hard enough to scratch diamond. |
