Nano-alumina for electronic ceramics

Nano-alumina for electronic ceramics Nano-alumina for ceramics
Nano-alumina can be used in functional ceramics, structural ceramics, transparent ceramics, textile ceramics, and electronic ceramics.
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 bending strength increases from single The 3-phase alumina ceramics are increased to 3-, and the fracture toughness of the material is also improved above.
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, nanopowder 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 embryo. , improves 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 both reach the maximum value< br/> Adding a small amount of nanometers can effectively improve the mechanical properties of the material. Alumina ceramics are sintered at ℃. When the added amount is , the flexural strength is , and the fracture toughness is .^/.
