Effect of Auxiliary on the Dispersibility of ZrB₂ Powder in the Liquid

Abstract:

The composite ZrB₂ powder coated A1₂O₃-Y₂O₃ prepared by co-precipitation method were densified via the spark plasma sintering (SPS) and then researched the oxidation resistance at high temperature. ZrB₂ powder must have the better dispersibility during the coating processing for obtaining the better coating effect. Effect of dispersant on the dispersibility of ZrB₂ powder in the liquid is researched in this paper, the results show ZrB₂ powder have the better dispersibility as the dispersant for PMAA and the content for 2vol%, which lay foundation for synthsising the better coating effect coated A1₂O₃-Y₂O₃-ZrB₂ composite powder.
