 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.).

6

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