Magnesium Fluoride (mgf2) – A Novel Sintering Additive for the Preparation of Transparent YAG Ceramics Via SPS

The effect of MgF2 as a sintering additive for the preparation of YAG ceramics via spark plasma sintering (SPS) is investigated with promising results, as nearly complete densification (0.58% porosity) is achieved at relatively low temperature and moderate pressure. Higher temperature and dwell time resulted in a translucent/transparent body. On the other side, significant grain growth was observed with MgF2 addition.
