指出了在稀薄气态介质中凝聚金属蒸气而制取超细微粉(直径为10—10~3埃)的可能性,研究了微粉形成的过程及其一般规律,对微粉形成的机理和形成的动力学过程进行了初步探讨.在附录中介绍了制取直径为70—170埃的少量鋁等金属微粉的直流电弧装置.
The possibility of producing ultrafine powder (diameter of 10-10 ~ 3 angstroms) by condensing metal vapor in dilute gaseous medium is pointed out. The formation process of powder and its general rule are studied. The formation mechanism and formation of micropowder are studied The course of the study was initially discussed.In the appendix, a DC arc device for preparing a small amount of metal powder such as aluminum with a diameter of 70-170 angstroms was introduced.
