摘要： A process for the production of extra fine spherical metal powders by chemical vapor deposition and dissolution techniques, including metal carbonyls, wherein the metal containing process gas is propelled upwardly through a heated reactor. By employing an upward gas flow as opposed to the conventional downward gas flow, a closer approximation of theoretical plug-flow velocity profiles are achieved thusly resulting in a desirably narrower size particle distribution obviating or reducing the need for subsequent classification techniques

摘要翻译： 通过化学气相沉积和溶解技术（包括金属羰基化物）生产超细球形金属粉末的方法，其中含金属的工艺气体向上推动通过加热的反应器。 通过采用与传统的向下气流相反的向上气流，实现理论塞流速度分布的更接近的近似，从而导致期望的较窄尺寸的粒子分布消除或减少对后续分类技术的需要
