Powder calcination involves heating a powdered material to high temperatures to cause chemical or physical changes, such as the removal of volatile components, crystallization, or phase transformations.

The types of powders that can undergo calcination are diverse and can include:

Metal powder, zinc oxide, aluminum oxide, titanium dioxide, calcium oxide, calcium carbonate, magnesium carbonate, pigments, rare earth, etc.

The goal of using kiln furniture in powder calcination is to ensure that the material is heated uniformly, protected from direct contact with heating elements or the furnace atmosphere, and processed in a controlled and efficient manner.
