99% Al203 Aluminium Oxide Ceramic For Firing Powder
1.Description of Alumina ceramic boat
Ceramic materials for ceramic components generally have high melting point (mostly above 2000℃) and excellent chemical stability and best insulation at high temperature.Ceramic thermal conductivity for ceramic parts is lower than metal materials, and a good thermal insulation material.At the same time, the linear expansion coefficient of ceramics is lower than that of metals. When the temperature changes, ceramics component parts have good dimensional stability.
