TEMPERATURE STRESSES IN BARIUM-TITANATE-BASED SEMICONDUCTOR CERAMICS
V. N. Shut and A. V. Gavrilov UDC 536.21+621.319.1 Temperature stresses in barium-titanate-based semiconductor ceramics in the process of heating by an electric current have been investigated by numerical methods. The fracture of low-resistance thermistors by the delamination mechanism has been substantiated.
