Plate-shaped corundum (Polycrystalline Diamond, PCD) is a type of polycrystalline corundum synthesized under high temperature and high pressure, usually formed by the chemical reaction of micron-sized diamond particles under high temperature and high pressure. Plate-shaped corundum has extremely high hardness, wear resistance, chemical stability, and thermal conductivity, making it an important material in various high-end application fields such as cutting tools, abrasives, and thermal conduction materials.

Firstly, plate-shaped corundum has an extremely high hardness, second only to single crystal diamond, with a hardness of over 9000HV, far exceeding that of other metal and non-metal materials. Secondly, the wear rate of plate-shaped corundum is very low, which not only allows it to maintain sharpness for a long time but also reduces material wear and thermal loss, thereby improving work efficiency and energy utilization. In addition, plate-shaped corundum also has excellent corrosion resistance and thermal stability, allowing it to operate stably in high temperature, high pressure, and corrosive environments.

In the field of industrial production, the application range of plate-shaped corundum is very broad. For example, in the mechanical processing field, plate-shaped corundum can be used to manufacture various cutting tools, such as lathe tools, milling cutters, drill bits, planers, tools, abrasives, etc., which can effectively improve cutting efficiency and cutting quality. In the field of electronic technology, plate-shaped corundum can be used to manufacture high-power electronic devices, heat sinks, LED packaging, semiconductor manufacturing, etc., which can enhance the working efficiency and lifespan of electronic devices. In addition, plate-shaped corundum can also be used to manufacture various chemical reactors, high-temperature furnaces, and high-pressure containers, which can operate stably in high-temperature, high-pressure, and corrosive environments.

In summary, plate-shaped corundum is a high-performance material of significant importance. Its excellent physicochemical properties and broad application prospects bring infinite possibilities for technological innovation and industrial development.
