Overview

Physical and chemical properties:

Alumina (Al2O3)ceramic material as the main body, which is used for 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.

High temperature resistance, corrosion resistance and good insulation.

Application areas:

Chemical industry, machinery manufacturing, textile industry, food machinery, etc.
