Ceramic Foundry Sand

Overview of Fused Ceramic Sand:

Ceramic Foundry Sand, also called Ceramsite, fused ceramic sand, is kind of man-made spherical shape ceramic particles made by spraying process from the melting bauxite in an Electric Arc Furnace. The ceramic foundry sand provides a unique combination of spherical shape grain, chemistry, and physical properties that result in numerous performance advantages compared with Silica Sand or Zircon Sand.

lt provides an efficient way in the foundry industry to improve the quality of the casting, reducing the cost and avoiding environmental pollution, lt is also good substitution to Chromite and Zircon sand because of lower price. At present, ceramic foundry sand is acknowledged in the worldwide as the newest and the best ideal sand for the foundries and has a wide feasibility of applications.

Features and Advantages of Fused Ceramic Sand advantages:

1. Solid sphere: The shape of Ceramic Sand is spherical with smooth surface and less surface area and offering a very good flow ability and filling ability. To compare with other sands else, less binder is used at the same mold strength and higher venting ability. It also offers the excellent collapsibility.

2. Lower thermal expansion rate: It makes the dimensions of castings better, less crack and defect and higher output.

3. Lower breakage rate: Ceramic Sand has a higher density and a very lower breakage rate at the reclamation. It makes a better reclamation rate to reduce the waste sand to be favor to the environment.

4. High refractoriness: The major chemistry is Al2O3. PH appears neutral. It belongs to the refractoriness of the series of Aluminum and Silicon which has a very good refractory performance. It is suitable for all kinds of metal and alloy castings.

Applications of Fused Ceramic Sand:

Ceramic Foundry Sand also named ( Ceracite, Fused Ceramite, Ceramic Sand), It is made of high quality materials by arc melting from bauxite, our Ceramic Foundry Sand with reasonable price, the price is much better than zircon sand , chromite sand; especially low-expansion, non-sintered, not powder, not crack, sticky sand (to eliminate the negative impact of the cast body mass), regeneration performance, and increase the yield of the casting.

Fused Ceramic Sand can be used as raw materials for some castable, lining material, brick. Especially for large ladle castable, high-middle BF trough castable, gunning mix, precast, etc unshaped refractory materials. Also for some shaped refractory, like: corundum brick, corundum and mullite-corundum sagger, Corundum porous plug brick, whole spray gun, composite nozzle, high temperature kiln's lining.
