Fused Ceramite Sand Refractory Ceramics for Foundry

 Fused Ceramite Sand Refractory Ceramics for Foundry 

Fused Ceramite Sand is also called ceramic foundry sand,cerasite, ceraxite, cerasand, sunpearl. It is made from fine bauxite, by refused and blown to ball type. It is a revolutionary new artificial foundry sand, now highly regarded as an excellent substitute for chromite sand and zircon sand in the produce and use, environmentally friendly, while offering improved performance based upon a better refractory rating, lower specific gravity, and higher levels of AL2O3 in its composition. It is used as single sand, eliminating the need to mix other sands and can be reclaimed many more times than previously used sand. With advantage of fine surface smooth finish and air permeability, it is a new type casting material for precision casting, coated sand and self hardening sand etc. 

Fused Ceramite Sand Advantages

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

Main Physical and Chemical Character

  Fused Ceramite Sand  Application 

 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.).
6.Widely used as cleaning sand for copper and aluminum alloy castings.
