Due to the superplasticity of nano-alumina powder, it solves the shortcomings of limited application scope due to low-temperature brittleness. Among them, nano-alumina silicon carbide nanocomposites are the most significant, and their flexural strength changes from single-phase With the improvement of alumina ceramics, the fracture toughness of the material has also increased 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, and good dispersion. Widely used in various ceramics. During the powder extrusion molding process, nano-powder can be filled into the pores of micron alumina powder, reducing the pore size and increasing the molding pressure, which can reduce the number of pores, thereby increasing the density of the ceramic blank and improving the Density and mechanical properties of alumina ceramics after sintering. The addition of nanometers promotes sintering activity and helps to reduce the sintering temperature. When the sintering temperature is ℃, the flexural strength and fracture toughness reach the maximum value. The addition of a small amount of nanometers can effectively improve the mechanical properties of the material. Alumina ceramics are sintered at ℃. When the addition amount is %, the flexural strength is , and the fracture toughness is .&^/. Technical indicators:
