Abstract

Periclase fine grains have been formed by evaporating magnesium in mixture gases of Ar (80%) and O₂ (20%) at 13 kPa by heating at 1000°C. Forsterite fine grains have been produced by flushing SiO powders into the flame during MgO grain formation. Periclase and metal magnesium grains were also produced in atmosphere.
