For Ceramic Calcination (Sagger)

Powder calcination sagger is mainly applied in calcination of ceramic raw materials(alumina/zircon ball), heat treatment of inorganic coloring pigments, and in other various fields as well. Because this sagger is especially used at high temperatures, it must not only have volumetric stability at high temperatures and thermal characteristics, but also high mechanical strength.

Through careful selection of high quality raw materials, meticulous shaping and high temperature calcination of sagger, our product meets the most extreme quality standards and, therefore, highly regarded in various fields.
