Sagger firing

Sagger firing is a heating process used in ceramic manufacturing, specifically for firing cermets or metal-ceramic composites. During sagger firing, the mixture is placed in a protective container called a sagger, which shields the items from direct contact with the kiln’s flames or heat sources. This controlled environment ensures even heating and prevents contamination or damage. The process involves gradually heating the items to a specific temperature, holding that temperature to achieve proper bonding and sintering, then cooling down slowly. Sagger firing is crucial for producing high-quality, durable ceramic and composite components with precise properties.
