Popis:	1. In the article, results are given of an investigation of several technological properties of carbonyl molybdenum powders, obtained on the experimental apparatus in the laboratory for carbonyl metals. 2. As a result of microscopic investigations, it was established that the powder consists mainly of particles of dimensions up to 2μ. 3. Carbonyl molybdenum powders possess a well-developed specific surface area (0.6–1.8 m2/g) which, in particular, causes high activity in them during sintering. 4. The conditions were found for preparing fairly strong “grey” pressings of carbonyl molybdenum powders (with the introduction of a plasticizer or by preliminary heat treatment) with comparatively low specific pressing pressures (3–5 tons/cm2). 5. It was shown that the carbonyl molybdenum powders are actively sintered at 1200–1400°C (at 1400°C, samples are obtained with a porosity of 0.1%).
