The prospects for the use of BeO ceramics in electronic and other fields of technology and special instrument making are discussed. When using BeO ceramics in electronic engineering, one of the main parameters is its high thermal conductivity. Ceramics BeO in the temperature range 300 - 630 K has the highest values ??of thermal conductivity among all ceramic materials used in electronic engineering. The thermal conductivity of 170 ceramic samples made of BeO ceramics with the same configuration and dimensions, obtained from the same batch of the initial BeO powder, has been investigated. It was found that the average size of microcrystals and the density of the obtained samples have a decisive influence on the values ??of thermal conductivity.
