Sintering route

The main goal of most ceramic sintering routes is to obtain near-theoretical... 

Figure 13.3 shows the variation of the elastic modulus of the composites with increasing LaP04 addition done by two different sintering routes. The decrease in elastic modulus attributed to LaP04 concentration can be explained by the rule-of-mixture. 

For some applications, better control on porosity is required and alternatives to solid-state synthesis methods have been sought requiring synthesis temperatures much lower than those used for the sintering route (1,600-1,800°C). 

Thorium fuel has also been produced along two alternative routes, the cold pelletization and sintering route, and e pellet impregnation method used for (Th -I- U) MOX. This latter method uses an interesting technique in which Th02 pellets of low density are suspended in a high-temperature uranyl nitrate bath where they soak up The conven-...

Developments in this field, permitting controlled deposition of complex chemical compositions will lead to greater exploitation of these processes. Although these techniques will not be discussed further here, (see chapter 9) there are lessons arising from them which can be applied to the powder-fabrication-sintering route. The most important of these is the small number...
