CERAMIC FOUNDRY SAND
ceramic sand is a spherically shaped bauxite sand manufactured by melting bauxite in an Electric Arc Furnace followed by a proprietary spraying process. ceramic sand 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.
CERAMIC SAND ADVANTAGES
- SAFE – to environment compared with silica (silicosis) and zircon sand
- longer work life and reduction of sand usage.
- 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
