Description

A zirconia-sagger, also called a zirconia crucible or saggar is a kind of ceramic container that is that is used in high-temperature applications. It is made of zirconia which is an extremely refractory material that is known for its superior resistance to chemical and thermal heat. Zirconia saggars can be found in various industries, including ceramics, metallurgy and powder processing. They are engineered to resist extreme temperatures and create protection for the materials during heating or firing treatment processes. These saggars are of good thermal stability and are able to endure temperatures as high as 2400degC (4352degF) or higher. They have a low thermal expansion coefficient that means they are able to resist breaking or cracking under extreme temperature fluctuations.

zirconia-saggars are suitable containers for high-temperature applications that require high thermal stability and chemical resistance, as well as mechanical durability, and protection for the material that are being processed.
