摘要：

Prospects are discussed for the use of BeO-ceramic in electronic and other fields of technology and special instrument building. With use of BeO-ceramic in electronic technology one of the main parameters is its high thermal conductivity. Analysis of publications shows that BeO-ceramic in the range 300-500 K exhibits the highest thermal conductivity among all ceramic materials used in electronic technology. Results are provided for a study of the thermal conductivity of 170 ceramic specimens made from BeO-ceramic with an identical configuration and dimensions prepared from one batch of BeO starting powder. It is established that the average size of microcrystals and the density of specimens have a defining effect on thermal conductivity.
