Polycrystalline Diamond (PCD) is a polycrystalline corundum synthesized under high temperature and high pressure. It is usually formed by chemical reaction of micron-sized diamond particles under high temperature and high pressure. Tabular corundum has extremely high hardness, wear resistance, chemical stability and thermal conductivity. It is an important material in various high-end application fields such as cutting tools, abrasives and heat conduction materials.
First, tabular alumina has extremely high hardness, second only to single crystal diamond, with a hardness of more than 9000HV, which is much higher than other metal materials and non-metal materials. Secondly, tabular alumina has a very low wear rate, which not only keeps it sharp for a long time, but also reduces material wear and heat loss, thereby improving work efficiency and energy utilization. In addition, tabular alumina also has excellent corrosion resistance and thermal stability, and can operate stably in high temperature, high pressure and corrosive environments.
In the field of industrial production, the application range of tabular corundum is very wide. For example, in the field of mechanical processing, tabular corundum can be used to manufacture various cutting tools, such as turning tools, milling cutters, drill bits, planers, knives, abrasives, etc., which can effectively improve cutting efficiency and cutting quality. In the field of electronic technology, tabular corundum can be used to manufacture high-power electronic devices, heat sinks, LED packaging, semiconductor manufacturing, etc., which can improve the working efficiency and life of electronic devices. In addition, tabular corundum can also be used to manufacture various chemical reactors, high-temperature furnaces and high-pressure containers, etc., which can operate stably under high temperature, high pressure and corrosive environments.
In short, tabular corundum is a high-performance material of great significance. Its excellent physical and chemical properties and broad application prospects bring unlimited possibilities for scientific and technological innovation and industrial development.
