Superabrasives have special properties unmatched by other materials and have become an irreplaceable new material in industrial applications. At present, they have been widely used in metallurgy, petroleum drilling, construction engineering, machining, instrumentation, electronics, aerospace as well as other modern cutting-edge scientific fields. The stone industry, consuming the largest amount, will be extremely difficult to develop without super-hard abrasives and tools. Today we will take a look at the basic knowledge of this super powerful superabrasive.
Superabrasive refers to a material whose hardness can challenge that of diamond. At present, the main industrial super-hard abrasive are cubic boron nitride and diamond, but there are more super-hard materials in development, such as boron carbide, twin diamond, silicon carbide and other group III and group IV compounds.
Diamond is currently known as the hardest substance in the world. In addition, the hardness of C60 may not be poorer than that of diamond, but it has not been determined yet. The hardness of cubic boron nitride is second only to diamond. The hardness of these two superhard materials is much higher than the that of other materials, including abrasive materials, such as corundum and silicon carbide, as well as hard tool materials, such as hard alloy and high-speed steel.
Therefore, superabrasives are suitable for manufacturing tools for processing other materials. It is excellent and indispensable especially for processing hard materials. Thus, super abrasives have been widely used in industry, in other words, there is a broad super abrasives market.
There is 30-year history for China superabrasives since the first laboratory synthesis of diamond in 1963. China superabrasives started from scratch, grew from insignificance to dominance, and developed from experiments in laboratory to commercial production. It has become the world's largest diamond producer, and the output of synthetic diamond has ranked first in the world. In addition, diamond and cubic boron nitride abrasive, which have been widely used in industrial applications and gradually developed from single crystal particles to polycrystalline and new superhard materials. The development of superabrasives in China is indeed promising.
