The role of the milling step on the sintering behaviour of monazite powder LaPO4. Densification and resulting microstructure.
Abstract
Sintering behaviour of monazite powder was investigated as a function of the powder milling conditions. To this aim, two techniques were used: attrition-milling and mixer-milling. We show that it is of prime importance to control all the milling parameters in order to obtain controlled microstructure and to avoid abnormal grain growth or residual large porosity.
