Paper Title:
The Effect of Particle Size on the Properties of Alumina-Based Ceramic Core
  Abstract

As source of ceramic core, the raw materials play an important role in determining the properties of ceramic core. In this paper, the effect of matrix Al2O3 particle size on the properties of ceramic core during fabricating is mainly studied and discussed, the test results show that reasonable particle size match of coarser, middle and finer matrix Al2O3 will be beneficial for properties of ceramic core. Matrix Al2O3 powders with double peak or multi-peak can form denser packing and help to increase the ceramic core’s strength than powders with single peak can. The influence of middle Al2O3 particle size is great for its large proportion in matrix materials, and its optimal particle size range is between 23~28µm.
