Is boron harder than tungsten

The key difference between tungsten carbide and boron carbide is that boron carbide is harder and stiffer than tungsten carbide. Both tungsten carbide and boron carbide are industrially important materials that are very hard and stiff than steel. Given h-BN's structural similarities to graphene, it also was expected to be brittle. That isn't the case. Hexagonal boron nitride's fracture resistance is about 10 times higher than graphene's, and h-BN's behavior in fracture tests was so unexpected that it defied description with Griffith's formula. Unlike other fillers in literature, such as silica or silicon nitride, which absorb water under ambient conditions, hBN only absorbs water when directly immersed in water. The strongest material in the universe may be the whimsically named "nuclear pasta." You can find this substance in the crust of neutron stars. This amazing super-dense material is 10 billion times harder to break than steel. Diamond is the hardest known mineral. It is a high-symmetry allotrope of carbon (C). It has a Mohs "scratch" hardness of 10, which makes it the hardest mineral. Summary: A team of scientists has calculated the strength of the material deep inside the crust of neutron stars and found it to be the strongest known material in the universe. Azidoazide azide is the most explosive chemical compound ever created. It is part of a class of chemicals known as high-nitrogen energetic materials, and it gets its "bang" from the 14 nitrogen atoms that compose it in a loosely bound state. This material is both highly reactive and highly explosive.
