The Study on Properties of Soluble Alumina Based Ceramic Cores

Abstract:

The effect of the sintering temperature, quartz and sodium phosphate content on the core strength,shrinking percentage and solubility of alumina matrix ceramic cores was investigated．The results show that：the more the quartz is, the higher of the bending, tensile strength at room temperature of core are;It has the extreme point when quartz is 10wt%, then decreases slightly.The shrinkage rate and the room temperature strength of core increases with the rising of sintering temperature,but decreases with the increasing of content of sodium phosphate. Furthermore, the effect of the sintering temperature,quartz powder and sodium phosphate content on solubility of core was discussed.
