    摘要： A finely divided metal-containing compound can be efficiently prepared by irradiating a mixed vapor phase of an organometallic compound in a concentration to exceed a specified lower limit and a reactant gaseous compound with laser beams having an incident energy density to exceed a specified lower limit. When the reactant gaseous compound in the vapor phase is an oxygen-containing compound, e.g., air, the resultant powdery product is an oxide of the metallic element of the organometallic compound. When the reactant gaseous compound in the vapor phase is a halogen-containing compound, e.g., methyl halides, the resultant powdery product is a halide of the metallic element of the organometallic compound. When the reactant gaseous compound is a second organometallic compound, of which the metallic element is not the same as the metallic element in the first organometallic compound, the resultant powdery product is a composite metallic powder of which the distribution of the two metallic elements is uniform throughout each particle. No particles of either one of the metallic elements alone are contained in the powder as evidenced by the EPMA analysis.

    摘要翻译： 可以通过用浓度超过规定的下限的有机金属化合物的混合气相和具有超过规定下限的激光束的反应性气体化合物来有效地制备细分的含金属化合物。 当气相中的反应性气体化合物是含氧化合物例如空气时，所得粉末产物是有机金属化合物的金属元素的氧化物。 当汽相中的反应性气体化合物是含卤素的化合物，例如甲基卤时，所得的粉末产物是有机金属化合物的金属元素的卤化物。 当反应性气态化合物是第二有机金属化合物时，其金属元素与第一有机金属化合物中的金属元素不同，所得粉末产物是复合金属粉末，其中两种金属元素的分布均匀 遍及每个粒子。 如EPMA分析所证明，粉末中不含有任何一种金属元素的颗粒。
