EFFECT OF CURING PARAMETERS ON SELECTED TECHNOLOGICAL PROPERTIES OF THE MOULDING SAND WITH INORGANIC CORDIS BINDER USED FOR ABLATION CASTING OF ALUMINIUM ALLOYS

摘要

Moulding sands made by the Cordis technology achieve high bending strength with only a small amount of the binder added. Their strength is much higher than the strength of the sands based on the chemically cured hydrated sodium silicate.
