Electrical method of granulometric analysis of metal powders

  • Published:
Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Conclusions

A method of granulometric analysis of metal powders in the size range of 2–100 microns has been described. The analysis time depends on the desired resolving powder and amounts to several minutes. When the analysis is carried out, the volume of each particle of the powder to be analyzed is transformed into the amplitude of an electrical pulse. The granulometric characteristics can be obtained by amplitude analysis of the pulses carried out by means of standard electronic apparatus. The method has been used for the analysis of niobium powders.

The data thus obtained allow this method to be recommended for the technical testing of powders.
