文摘The influence of three different Al2O3 powder art self-flowing alumina castabie was studied , Max-imum compaction of sample wascomputed by An-dresen Equation . The result showed that the Al2O3 powder, which has much smaller particle size, could improve the microstructure and the mechanical properties of castabie under room temperature and high temperature. With the same powder size, the room temperature strength of the castabie added with Al2O3 powder properties of which were altered by adding mineralizing agent, was higher than that of the castabie added with common Al2O3 powder, but the flowability of these three different castabie was almost thesame.
