Powder calcination is a thermal treatment process used to drive chemical and physical transformations in finely divided materials (powders) at elevated temperatures. It is a critical step in the production of advanced materials for industries such as:

• Lithium battery materials (e.g., cathode/anode powders)
• Ceramics and refractories
• Metallurgical powders
• Pigments (e.g., titanium dioxide, iron oxide)

During calcination, the precursor powders are loaded into saggers or trays, which are part of the kiln furniture system. The selection of appropriate kiln furniture, especially saggers, is critical for ensuring powder purity, product consistency, and long-term production efficiency.
