Production name: Calcined zircon flour
Calcined zircon powder is primarily used as a surface coating material for high-end lost wax precision casting. It is made from natural zircon sand clinker imported from Australia, which undergoes professional grinding and high-temperature calcination treatment. After being maintained at a temperature above 1300 degrees for more than 20 hours, low-melting-point alkaline oxides and organic compounds are ablated. This makes its high-temperature physical and chemical properties more stable, with better refractoriness and an extremely low thermal expansion coefficient. The surface coating material is in its optimal state in terms of suspension, permeability, fluidity, and application properties. The extremely low impurities reduce the occurrence of sand adhesion defects and improve the surface finish of investment casting parts.
