• Uniform component composition
• Stable grain size distribution and air permeability
• High refractoriness (1825°C)
• High resistance to wear, crush and thermal shock
• Little thermal expansion
• Excellent fluidity and filling efficiency owing to being spherical
• Highest reclamation rate in the sand loop system
