 Precision ceramic materials have the following applications in industry

1.used to improve the mechanical strength of ceramic materials

Structural ceramics are materials characterized by mechanical properties such as strength, stiffness, toughness, wear resistance, hardness and fatigue strength.

2.used to improve the super plasticity of ceramic materials

Only when the particle size of the ceramic powder is small to a certain extent, the superplastic behavior can be generated in the ceramic material. The reason is that the nanocrystals. of the grains helps to produce relative slip between the grains, so that the material has plastic behavior.

The super plasticity of nano-ceramics has potential applications in electronic, magnetic, optical and bioceramics. The low temperature super plasticity, ductility and high fracture toughness of nano-ceramics will make them become new structural and functional materials with excellent characteristics of both ceramics and metals (such as high strength, high hardness, high toughness, high temperature resistance, corrosion resistance, easy processing, etc.). In aviation precision ceramics, medical precision ceramics, electronic precision ceramics, machinery, information and many other fields have unlimited broad application prospects.

3.applied to the preparation of electrons

The reason why nano ceramic powder is widely used in the preparation of electronic ceramics is that the nano grain of ceramic powder will cause a great increase in the number of grain boundaries, when the grain size in the ceramic is reduced by an order of magnitude, the surface area of the grain and the volume of the grain boundary are also increased by a corresponding multiple.

4.used in the preparation of ceramic tool knife

The emergence of nanotechnology and the industrial production of nano-powders make the preparation of cermet knives a reality.

The hardness of the precision ceramic knife is very large, and the industrial part is used to cut metal, and even can be used to cut steel. Structural ceramics as a new type of precision ceramic material, this is a ceramic blade. Its unique performance has broken people's radical impression of ceramics, and is gradually being 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 the world's hardest material - diamond (10), we all know that the harder the material, the sharper the blade can be made, but sharp also has a price, because of the hard, so more brittle, low toughness cannot specifically cut hard objects, which is determined by the characteristics of the material.

Compared with the industrial ceramic knife (repairing plastic flash) and the civil ceramic knife (cutting fruit), the material is not much different, and the structure will be different. But you can't cut anything hard. It's just hard to wear. It lasts a long time without grinding.
