Problems solved by technology

[0003] During the production and processing of nano-ceramic materials, some raw materials need to be ground. In the prior art, ball mills are usually used to grind nano-ceramic materials. However, some materials need to be pulverized in a pulverizer before grinding. During the process, some raw materials will adhere to the surface of the inner wall of the pulverizer, and the utilization rate of raw materials is low;
[0004] At the same time, the existing nano-composite ceramic materials use their nano- or sub-micron materials, and add nano-titanium carbide, nano-boron nitride and nano-boron carbide to obtain high-strength nano-composite ceramic materials. Therefore, they have high hardness and high strength. However, its fracture performance is average and its brittleness increases. As a tool material, it cannot be used for a long time.
