Application   

Fine corundum alumina sagger, also known as the ceramic setter, is an essential tool for transporting and carrying the fired ceramic body in the ceramic kiln. These plates are made of high-purity corundum and mullite as the main raw materials. By combining the excellent properties of the two materials, a high temperature composite backing plate was created that offers numerous advantages and features for ceramic kiln operations. In this article, we will explore the advantages and functions of fine corundum plates in more detail.
