Introduction of Super-hard Material

May 30, 2022

Superhard material refers to materials with extremely high hardness, which can be divided into natural and artificial. Superhard materials mainly refer to diamond and cubic boron nitride. Diamond is known to be the hardest substance in the world, and the hardness of C60 may be no less than that of diamond, but it has not yet been determined. The hardness of cubic boron nitride is second only to diamond. The hardness of these two superhard materials is much higher than that of other materials, including abrasive materials corundum, silicon carbide and tool materials carbide, high-speed steel and other hard tool materials.

Therefore, superhard materials are suitable for making tools for processing other materials, especially in processing hard materials, they have unparalleled advantages and occupy an irreplaceable important position. For this reason, superhard materials have been widely used in industry. In addition to being used to make tools, superhard materials have some special properties in optics, electricity, and heat, and are an important functional material, which has attracted great attention. The properties and uses in this area are constantly being researched and developed.

Synthetic diamond is the hardest abrasive in the processing industry, the most effective heat dissipation material in the electronics industry, the best chip for semiconductors, the highest frequency filter for communication components, the most facsimile vibration film for audio, and the most stable anti-corrosion layer for mechanical parts, etc. It has been widely used in metallurgy, oil drilling, construction engineering, mechanical processing, instrumentation, electronic industry, aerospace and modern cutting-edge science.

Cubic Boron Nitride is a synthetic superhard material.

Cubic boron nitride (CBN) is a superhard material second only to diamond in hardness. It not only has many excellent properties of diamond, but also has higher thermal stability and chemical inertness to iron group metals and their alloys. As an engineering material, it has been widely used in the processing industry of ferrous metals and their alloys. At the same time, it has been applied in a series of high-tech fields due to its excellent thermal, electrical, optical and acoustic properties, and has become a promising functional material. Cubic boron nitride micropowders are used in precision grinding, lapping, polishing and ultra-finishing to achieve high-precision machined surfaces. It is suitable for binder systems such as resin, metal, ceramics, etc. It can also be used to produce polycrystalline composite sintered body, and can also be used as loose abrasive particles and abrasive paste.
