A new, unique technology of vacuum granulation of ceramic powders has been presented in this paper. Due to such granulation where the grain is of a few micrometers, it is possible to obtain die-stamping of apparent density equal 85% of theoretical density, while pressing the typical powder granulated products allows to obtain die-stamping density (including isostatic die-stamping) of not more than 55–63% of theoretical density. Such a high degree of powder material concentration, not possible with other methods, gives very good economical and technological results during burning process. Apart from detailed description of a device for vacuum granulation of ceramic powders, the paper presents the results of granulation, compacting/concentration and sintering ceramic powders.Presented technology is available for industry and has been tested on many powders applied in production of ferrites, refractory and traditional ceramics and cermets.
