Conclusions
The possibility of significantly improving the thermal-shock resistance of an A1N ceramic has been established. This is done by using compounds of a coarser grain composition and by adding Y2O3 and SiO2 additives.
The physicomechanical, electrophysical, and dielectric properties and the thermal-shock resistance of the newly developed ceramic have been determined. This ceramic can be taken as a promising material for high temperature electrical insulation purposes.
