Precision ceramic materials have the following applications in industry:

 

1. It is used to improve the mechanical strength of ceramic materials

 

Precision ceramic structural parts structural ceramics are materials characterized by mechanical properties such as strength, stiffness, toughness, wear resistance, hardness and fatigue strength.

 

2. It is used to improve the Superplasticity of ceramic materials

 

Only when the particle size of ceramic powder is small to a certain extent, can 2113 superplastic behavior be produced in ceramic materials. The reason is that the nanocrystallization of grains contributes to the relative slip between grains and makes the materials have plastic behavior. About

 

The Superplasticity of nano ceramics has potential applications in electronics, magnetism, optics and bioceramics. Nano ceramics may have low-temperature superplasticity, ductility and high fracture toughness, which will make them new structural and functional materials with excellent characteristics of ceramics and metals (such as high strength, high hardness, high toughness, high temperature resistance, corrosion resistance, easy processing 5261, etc.), which are used in Aviation Precision Ceramics, medical precision ceramics, electronic precision ceramics, machinery Many 4102 fields such as information have infinite and broad application prospects.

 

3. Applied to the preparation of electronic

 

The reason why nano ceramic powder is widely used to prepare electronic ceramics is that the nanocrystallization of ceramic powder grains will greatly increase the number of grain boundaries. When the grain size in ceramics decreases by an order of magnitude, the surface area of grains and the volume of grain boundaries also increase by a multiple of 1653.

 

4. Knife for preparing ceramic tools

 

The emergence of nanotechnology and the industrial production of nano powder make the preparation of cermet knife a reality.

 

The hardness of precision ceramic knife is very large. In industry, it is used to cut metal and even steel. As a new type of precision ceramic material, structural ceramic is a ceramic blade. Its unique performance has broken people's radical impression of ceramics. It is gradually recognized by the society and applied to more and more engineering fields.

 

Ceramic knives are generally made of zirconia precision ceramic materials, with a hardness of 9, second only to diamond (10), the hardest material in the world. As we all know, the harder the material, the sharper the blade can be made, but sharpness also comes at a price. Because it is hard, it is brittle and has low toughness. It is not able to cut hard objects, which is determined by the characteristics of the material.

 

Compared with the civil ceramic knife (cutting fruit), the industrial ceramic knife (trimming plastic flash) is not much different in material, but different in structure. But you can't cut anything hard. This thing is wear-resistant and can be used for a long time without grinding.
