Important Indicators Affecting Rheological Properties of Alumina Slurry

Alumina ceramics is a ceramic material with alumina (Al2O3) as the main body, which is used in thick film integrated circuits. Alumina ceramics have good conductivity, mechanical strength and high temperature resistance. It should be noted that ultrasonic cleaning is required. Alumina ceramics is a kind of ceramics with a wide range of uses. Because of its superior properties, it has been widely used in modern society and meets the needs of daily use and special properties.

Alumina has been widely used in industrial structural materials for its excellent properties such as high temperature resistance, corrosion resistance, hardness resistance, high wear resistance, electrical insulation, and oxidation resistance.

Its preparation process directly affects its performance. In the preparation method of alumina ceramics, there is a method that is widely used, that is, grouting, which has low cost, simple process and high yield. In the grouting process, The preparation of the slurry is more critical, requiring the slurry to have the characteristics of low viscosity, high stability, high dispersibility and high solid content.
