Nano alumina can be used for functional ceramics, structural ceramics, transparent ceramics, and textile machinery ceramics.

Due to the superplasticity of nano alumina powder, the limitation of application range due to low-temperature brittleness has been solved. Among them, the nano aluminum oxide silicon carbide nanocomposite material is the most significant. Its bending strength has increased from 300-400Mpa of single-phase alumina ceramics to 1GPa, and the increase in fracture toughness of the material is also more than 40%.

Adding nano alumina to ceramic substrates can not only improve the sintering performance of the substrate, but also significantly enhance the thermal stability of the alumina substrate material.

Domestic research institutions have confirmed that adding nano alumina can increase thermal stability by 2-3 times and flatness by 1.5 times. Our company's ceramic specific nano alumina has the characteristics of high purity, small particle size, and good dispersibility, and is widely used in various ceramics.

During the powder extrusion molding process, nano α - Al2O3 powder can be filled into the pores of micrometer alumina powder, reducing the pore size; The increase in molding pressure can reduce the number of pores, thereby increasing the density of ceramic billets and improving the density and mechanical properties of alumina ceramics after sintering

The addition of nano a-Al2O3 promotes sintering activity and helps to reduce sintering temperature. When the sintering temperature is 1450 ℃, the bending strength and fracture toughness reach their maximum values

The addition of a small amount of nano a-Al2O3 can effectively improve the mechanical properties of the material. When sintering alumina ceramics at 1450 ℃, the bending strength is 415mPa and the fracture toughness is 4.1MPa · m ^ 1/2 when the addition amount is 10%.
