用电子显微镜研究了金属在80%Ar和20%O_2混合气体中燃烧产生的氧化物烟颗粒。CaO烟雾颗粒生长在单晶立方体。In2O3、Sb2O3、Bi2O3、Cu2O、SnO2、CuO和WO3烟雾颗粒以单晶八面体生长，或者有时以球形或更复杂的多面体生长。具有层状结构的颗粒如SnO和PbO以薄板状生长。扫描电子显微镜观察表明，烟雾颗粒是由两个或两个以上的单个颗粒以一定的方向连接而成的。
Some oxide smoke particles which were prepared by burning metals in a gas mixture of 80% Ar and 20% O2 were studied by electron microscopy. CaO smoke particles grew in single crystal cubes. In2O3, Sb2O3, Bi2O3, Cu2O, SnO2, CuO, and WO3 smoke particles grew in single-crystal octahedra or sometimes grew in spheres or more complicated polyhedra. Particles with layer structure such as SnO and PbO grew in thin plates. It is shown by scanning electron microscopy that smoke particles grew by coalescence in which two or more single particles joined in definite orientations.
