Abstract

Gelcasting is a very useful technique for producing ceramic green parts with complex shapes. Although it has been successfully applied to ceramic systems consisting of micron size powders, there is little report on gelcasting of ceramics containing nanoparticles. In this work, ceramic system with nano-size ZrO₂-Y₂O₃-A1₂O₃ powders (30-40 nm in size) have been successfully gelcast to form complex-shaped parts. After pressureless-sintering, the Y-TZP/Al₂O₃ nanocomposites with an average grain size of 220 nm are successfully fabricated.
