Tungsten carbide powder is an important industrial raw material, mainly used in the production of carbide carbide. It has the characteristics of high hardness, low thermal expansion coefficient and high compressive strength. These physical properties make the WC powder occupy a very important position in the manufacturing industry.

The particle size of tungsten carbide powder has an important influence on its application performance. According to different particle size requirements, tungsten carbide powder can be divided into WC10, WC30, WC50 and WC100 and other grades. These different grades of WC powder are suitable for different production requirements.

In the production process, the carbonization temperature and time have a significant effect on the particle size of carbide powder. Generally speaking, the higher the carbonization temperature, the longer the carbonization time, the thicker the particle size of tungsten carbide powder. Therefore, by precisely controlling the carbonization temperature and time, a carbide powder can be prepared to meet specific needs.

In conclusion, Metal powder, as an important industrial raw material, has wide application prospects in the manufacturing industry. By optimizing the production process and parameter control, the tungsten carbide powder with excellent performance can be prepared, providing strong support for the development of the manufacturing industry.

WC powder, as a key raw material for the production of cemented carbide, has attracted much attention in the industrial field for its excellent hardness characteristics. It is like a bright pearl in the manufacturing industry, with a black hexagonal crystal structure, exuding a unique metallic luster, and its hardness performance is close to that of diamond. It also has good electrical and thermal conductivity. From the perspective of physical parameters, the melting point of tungsten carbide powder is as high as 2870℃ and the boiling point is 6000℃. Such a high melting point makes its internal atomic bonding force extremely strong, and it is difficult for general temperature changes to destroy its atomic structure, thus laying the foundation for its high hardness. In the common hardness measurement system, the Mohs hardness of tungsten carbide powder is between 9 and 9.5, which is only inferior to diamond and cubic boron nitride. The Vickers hardness can reach up to 1800HV, and the microhardness reaches 17300MPa. These data intuitively show its extraordinary hardness.

The reason why WC powder is so hard is closely related to its unique crystal structure. At the microscopic level, tungsten carbide presents a hexagonal closest packing structure, in which carbon atoms and tungsten atoms are cleverly arranged alternately. This atomic arrangement is highly ordered and compact, which makes the distance between atoms short and the interatomic force, that is, the chemical bond energy, extremely strong. When the outside world tries to exert pressure, wear or damage the tungsten carbide powder, it needs to overcome the strong interatomic force. Figuratively speaking, this crystal structure is like a carefully constructed solid fortress. The atoms are like the cornerstones of the fortress, fitting tightly to each other and firmly connected by strong chemical bonds “glue”. It is difficult for external forces to easily shake the atomic position, which gives the tungsten carbide powder an extremely high hardness.
