Nano-alumina ceramic toughening agent for ceramic toughening and whitening
Nano-alumina can be used as a toughening and whitening agent for functional ceramic structures, transparent ceramics, textile machines, and ceramics.
Due to the superplasticity of nano-alumina powder, it solves the shortcomings of limited application range due to low-temperature brittleness. Among them, nano-alumina-silicon carbide nanocomposites are the most significant. Their flexural strength is higher than that of single-phase alumina. Ceramics - The fracture toughness of the material has been improved by more than %.
Adding nano-alumina to the ceramic substrate can not only improve the sintering performance of the substrate but also greatly improve the thermal stability of the alumina substrate material.
Domestic research institutions have confirmed that adding nano-alumina can improve thermal stability and flatness. Our company's special nano-alumina for ceramics has the characteristics of high purity, small particle size, good dispersion and is widely used in various applications. kind of ceramics.
During the powder extrusion molding process, nano-powder can be filled into the pores of micron alumina powder, reducing the pore size. Increasing the molding pressure can reduce the number of pores, thereby increasing the density of the ceramic blank and improving oxidation. Density and mechanical properties of aluminum ceramics after sintering
The addition of nano-promotes the sintering activity and helps to reduce the sintering temperature. When the sintering temperature is ℃, the flexural strength and fracture toughness reach the maximum value
A small amount of nano- Adding can effectively improve the mechanical properties of the material. When the sintered alumina ceramics are sintered at ℃, the flexural strength is % and the fracture toughness is .d^/.
