Ceramsite 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 other foundry sands. Our SuperSand (Ceramsite) performs very well comparatively to Chromite, and Zircon sands and has replaced these sands in many foundry applications. The grain surface is much smoother than other foundry sands, leading to better castings.
Benefits of Ceramsite :
- SuperSand (Ceramsite) 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
- SAFE – to environment compared with silica (silicosis)
- 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 other foundry sands
