The effect of sintering ramp rate on the sinterability of forsterite ceramics

In the present work, pure forsterite (Mg2SiO4) powder was successfully synthesised via ball milling and subsequent heat treatment as an evident from X-ray diffraction analysis. The synthesised powder were formed by powder agglomerates that were made up of loosely packed fine particles. Then, the for...
