Trebol Milled Zircon Flour 325 50lb Bag

Zircon sand - 50 lbs.

• Granular form
• Naturally occurring refractory mineral and is therefore subject to variability
• Chemically inert
• Stable to very high temperatures
• Very high thermal conductivity
• Acts as a chill to eliminate metal mold reactions and burn-in, resulting in a smooth cast surface
• High density provides excellent flow characteristics in a primary slurry
• Round grains do not cause defects such as rough casting surfaces

Zircon is a naturally occurring refractory mineral. It is chemically inert and is stable to very high temperatures. Zircon has a very high thermal conductivity and acts as a chill to eliminate metal mold reactions and burn-in resulting in a smooth cast surface. Zircon is available in both flour and granular form. Zircon is almost exclusively used in the primary slurry and as a primary stucco. Because of its high density, zircon provides excellent flow characteristics in a primary slurry. The round grains produce smooth casting surfaces, reducing rough casting defects.
