Ceramic Foundry Sand

Refratory Engineers (REI) offers a unique Foundry Sand by the name of SuperSand. SuperSand is a ceramic sand. SuperSand is a spherically shaped bauxite sand manufactured by melting bauxite in an Electric Arc Furnace followed by a proprietary spraying process. SuperSand beaded foundry sand provides a unique combination of spherical shape grain, chemistry, and physical properties that result in numerous performance advantages compared with Silica Sand, Chromite Sand, or Zircon Sand.

SuperSand Advantages

  • SAFE - to environment compared with silica (silicosis) and zircon sand
  • SuperSand offers longer work life and reduction of sand usage.
  • SuperSand’s spherical shape compared with angular shaped grains allows for easier separation from cast parts and improved collapsibility resulting in lower scrap and casting efficiency.
  • Lower Thermal expansion and Thermal Conductivity. Casting dimensions are more accurate and lower conductivity provides better mold performance.
  • Requires 40-50% less resin
  • Can be used as a single sand
  • Offers lower true specific gravity and specific surface area
  • Improved durability compared with silica and chromite
