The Ceramic Foundry Sand exhibits exceptional refractoriness (greater than 1790 °C), high thermal conductivity at elevated temperatures, low thermal expansion, and superior roundness—99% roundness rate—leading to excellent flowability and superior mold and core performance.
Available in three grades — ZCF30, ZCF40 and ZCF60 — each grade is optimized for specific particle size distributions to suit various precision casting, foundry molding, core-making and refractory castable raw material applications.
Applications include:
Precision casting for ferrous metals (steel, cast iron)
Precision casting for non-ferrous metals (aluminum, copper alloys)
Foundry sand molding and core-making
Raw material for refractory castables and high-temperature furnace linings
Advanced ceramic shell mold systems and complex metal casting with tight tolerances.
Technical specifications:
Chemical composition (typical): Al₂O₃ ~72.6%, Fe₂O₃ ~2.5%, K₂O 0.48%, SiO₂ ~15.3%, TiO₂ ~2.6%, bulk density ~1.98 g/cm³.
Physical properties: Roundness rate 99%; refractoriness >1790 °C; thermal conductivity at 1200 °C ~5.27 W/m·K.
Particle size distributions vary by grade (for example, ZCF40 average size ~44.1 µm).
Packaging options: standard 25 kg bags, 500 kg bags, 1000 kg jumbo bags or customized packaging per customer requirements.
With this product, Ze Xi Mineral positions itself as a supplier for foundries and casting operations pursuing higher precision, lower defect rates and improved mold/core performance.
