With lower thermal expansion rate and bulk density, good fire-resistant and crushing-resistant ability,ceramic foundry sand has become the ideal choice and adopted by customers from Japan, South Korea and the EU, etc compared to Chromite sand and Zirconium sand.
With good flowability namely good roundness and filling character and can be easily removed afterwards. Good formability and high strength of mold can be achieved and meanwhile, less binder is required;
With low thermal expansion which makes it suitable for precision foundry, causing less cracks and
With low thermal expansion which makes it suitable for precision foundry, causing less cracks and finally raising the output;
With good crushing-resistant ability and can be reused repeatedly and is environmental friendly due to less dust caused;
With good fire-resistant which is above 1800℃(3272℉)that is suitable for precision foundry for kinds of metals and alloys;
With low bulk density which requires less sand to make the same mold(core) compared to Chromite sand and Zirconium sand;
With pH value 7.6 and stable chemical character which requires lower acid consumption.
