Uses and features of Zircon Sand

Application Features
Sand molds and cores Metal chills
  • Resists metal penetration and “burn in”
  • Low thermal expansion aids dimensional accuracy
  • Resists metal reaction with most alloys
  • Reduced cleaning and machining
  • Low binder requirement
  • High thermal conductivity
Prime coat slurry
  • Excellent casting surface
  • Low reactivity with alloys
Back-up slurry and stucco
  • Exhibits non-wetting surface to molten metals
  • Low thermal expansion
Cores
  • Excellent refractory properties
Shell molds
  • Dimensional accuracy
