The urgency of the problem specifies the development of modern technology, in particular the production of capacitors, which is impossible without the creation of new materials to improve the parameters of products. The work aim is solving an applied technical problem – the creation of capacitors with improved electrical characteristics. The technological scheme of production of modified condenser powders, the chemical composition and electrical characteristics of the capacitor tantalum powder are investigated. The effect of sintering temperatures (1500-1600 °C) on the physical and electrical characteristics of the capacitor tantalum powder is studied. Main characteristics of the powder are charge, bulk density, particles size according to Fisher, strength of unsintered anode. To obtain products that meet modern requirements, the existing technology for the production of agglomerated powder (AGP) is improved by introducing additional operations, such as compacting the material before loading into the furnace, as well as re-sintering. Several variants of preparation of the primary condenser tantalum powder for thermal treatment at temperatures 1500-1600 °C are studied. The favorable effect of preliminary chemical treatment with solutions of hydrochloric and hydrofluoric acids with the addition of hydrogen peroxide of the initial tantalum powders on the increase of the specific charge of the finished AGP was established. To obtain AGP with the optimum properties, it is necessary to use tantalum containers with lids for the dehydration of the primary condenser powder. Obtained with the free filling of the hydride into the box agglomerate of the AGP has a lower bulk density and an average grain size according to Fisher, as well as a greater strength of the unsintered anodes compared to the powder obtained by compaction. Nevertheless, the AGP obtained by compacting the hydride before agglomeration allows obtaining AGP with characteristics meeting all modern requirements. This characteristics are charge in the range of 4000-4500 μC/g, the leakage current is not more than 0.23 nA/μC, the bulk density in the range 3.5-4.0 g/cm3, Fischer particle size in the range of 8-1 micrometer, strength of the unsintered anode more than 30 Н, magnesium content less than 3 ppm.
