マグネシウム蒸気と酸素の気相反応による酸化マグネシウム微粉体の合成

抄録

MgO powders were prepared by the vapor phase reaction of Mg vapor and O₂. Each MgO particle was a single crystal and had rectangular parallelepiped or cubic shapes. The lattice parameter was constant (4.211-4.214 A) independently of reaction conditions. The size of MgO particle was ranged from 0.005 to 0.4 pm and was related to the ratio [O₂]/[Mg] and the reaction temperature. The particle size decreased with increasing the ratio of [O₂]/[Mg]and with increasing reaction temperatures.
