Mullite Alumina Sagger For Calcining Metal Powder
1.About the product:
As a mullite kiln furniture material featuring excellent thermal shock resistance whose alumina content is up to 70% and good hot strength up to 1450°C.
The sagger can be applied to where the temperatures and/or chemical interactions preclude the use of lower temperature ceramic materials such as cordierite or fused silica but are not strict enough for high alumina which contains alumina of over 90%.
