Detailed Description
Sphercal Ceramsite Sand
Chemical Composition
Chemical Al2O3: 70% min ; Fe2O3: 5% max TiO2:5%max  SiO2 (%):8~20% 
MgO Content (%):0.5%max  CaO (%):0.5%max K2O:0.5%max Na2O:0.5%max
Physical Character
Grain type: ball, spherical
Angularity: 1.1 max, similar to ball
Packing density: 1.95-2.05 g/cm3
Refractoriness: 1790 C min
Thermal expansion: 0.13% (10 min at 1000 C )
Size: 10-14 mesh; 20-30 mesh; 30 mesh; 40-70 mesh; 100-140 mesh; 170 mesh
 Main Advantage
1.Stabe quality on the chemical composition
2.Perfect grain round shape and various grain sizes
3.High gas permeability
4.High temperature resistance
5.Good break down and fast curing and good release
6.Perfectly round shape with higher fluidity improves fill-in efficiency while reducing the resin level
7.Smooth surface of spherical shape greatly improves collapsibility after pouring
8.Very low thermal expansion ensures fewer or no casting defects such as veining and deformation
9.Excellent thermal conductivity and heat absorption capacity close to that of Zircon
10.Superior refractory equivalent to Zircon and Chromites 
Applications
1.Widely used in foundry technique like resin-bonded sand, sodium silicate sand, and clay- bonded sand for sand core and casting mould making
2.Replace chromite sand and widely used in sand core making like jacket core, oil duct core, tappet core of engine.
3.Replace chromite sand for steel casting facing sand and sub-layer of molding sand (backing sand).
4.Widely used as dry sand and sand box for EPC process and V method of casting processes.
5.Widely used as the main raw materials of advanced refractory products (Ladle drainage sand,gravity casting material, casting coating, etc.).
