Sintering of Particulate Composites

The excellent performance and subsequent reproducibility problems of these materials led Garvie and colleagues to study the mechanisms of these materials and subsequently control the process and resultant material and performance. 

The third type of zirconia-toughened body is that made by addition of Zr02 to some chemically different matrix, the most prominent of which is
