Abstract

In this paper, we present a novel sintering technique, called spark plasma sintering, that we apply for the synthesis of mineral aggregates used for experimentation. We show how dense polycrystalline aggregates of forsterite Mg2SiO4 and MgO mixed in various proportions can be obtained within minutes and with limited grain growth. Finally, we briefly mention the high-pressure experiments we performed with such samples.
