Preparation and Characterization of Stable ZrB2-based Ultra-High Temperature Ceramics Slurry by Aqueous Gelcasting

摘要：

　　Stable ZrB2-based ultra-high temperature ceramic slurries were prepared and characterized with a solid content 40 vol% by aqueous gelcasting which was suitable to form high quality and complexshaped ceramic parts.In the present work,Ammonium Citrate Tribasic (ACT) was used as the dispersant.The properties of ZrB2 slurry,and the influencing factors were investigated by conventional techniques such as sedimentation tests,particle size distribution measurements,electrokinetic measurements and rheological analysis.High solids loading and low viscosity slurry was obtained by controlling the optimal conditions for the ZrB2-based ceramic powders.
