FAQs
Q1: What is a Corundum Mullite Ceramic Saggar?
A Corundum Mullite Ceramic Saggar is a high-performance, heat-resistant container made from a mixture of corundum and mullite. These materials offer excellent thermal stability, thermal shock resistance, and low thermal expansion, making the saggar ideal for use in high-temperature applications such as kilns, furnaces, and other heat treatment processes.
Q2: What temperature range can Corundum Mullite Ceramic Saggars withstand?
Corundum Mullite Saggars can typically withstand temperatures up to 1400°C , depending on the specific formulation and design. This makes them suitable for extreme high-temperature processes.
Q3: Can Corundum Mullite Saggars be used in all types of kilns?
Yes, Corundum Mullite Saggars are compatible with most types of kilns, including electric, gas, and fuel-fired kilns, due to their ability to withstand varying temperature environments. They are particularly useful in ceramic, refractory, and metal heat treatment kilns.
