1. Product Description of Ceramic Sand

Ceramsite is also called as Ceramic foundry sand.It selects the high quality bauxite as main raw material,

then made into different size through the process of calcination, electric melting, granulation, and sieving.

Ceramic sand has high refractoriness over 1790℃, it can help to reduce the sand adhering to the casting

parts,especially when used for steel castings & stainless steel parts with higher temperature.So it is an

advanced substitute for quartz sand in casting industries.

3. Main Features of Ceramic Sand

Solid Sphere: Ceramsite has solid spherical shape with smooth surface,it will provide good flowability and

filling ability.

Low thermal expansion rate: it will guarantee the casting size, provide less crack and defect and improve

the output.

Low breakage rate: ceramsite has higher density and lower breakage rate at the reclaimation,which provide

one better reclaimation rate,then reduce the production cost.

High refractoriness: ceramsite contains Min. 70% Al2O3,which provide good refractory performance,then

suitable for all kinds of metal and alloy castings.

4. Main Applications & corresponding specification:

5. How to store the ceramic sand?

Use strong moisture-proof package;

Keep it in clean, dry and ventilated place;

Keep away from dust.

6. Why Ceramic Sand can replace the chromium sand as drainage sand?

Ceramic sand has lower bulk density and price compared with chromium sand,it will reduce the sand

consumption and final production cost.

Ceramic sand also has higher cast ratio,it will effectively reduce the strength of sintering layer,it is helpfu

to drain;

Its lower thermal expansion rate can reduce the expansion rate and improve the yield rate.
