Ceramsite Sand, also known as fused ceramic granules, is a high-grade alternative to quartz sand，is made of high-quality aluminum-vanadium as raw material, which is calcined, electrofused, granulated and sieved.
|Refractory Temperature||≥1790℃||Bulk Density||1.95-2.05g/cm3|
|Ture Density||3.4g/cm3||Thermal conductivity||1200℃|
|Coefficient of expansion||(20-1000 ℃) 6 × 10-6/℃||Grit Size||6-270mesh|
⒈Widely used in foundry technique like resinbonded sand, sodium silicate sand, and clay- bonded sand for sand core and casting mould making.
⒉It is suitable for the production of castings of various binders and various metal materials, and it is easy to clean sand, and the sand-mixing process is simple and convenient.
⒊ For most castings, the coating can be omitted, especially for castings with high quality requirements.
⒋Can effectively solves the problems of high casting cost and poor casting quality.
⒌The high degree of refractoriness and the high degree of compaction during molding can improve the surface quality of the casting and reduce the scrap rate in production
