High thermal-shock resistance of aluminum nitride ceramics

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.Translated from Ogneupory, No. 3, pp. 50–53, March, 1980.
