EFFECT OF GAMMA RADIATION ON THE DIELECTRIC PROPERTIES OF VACUUM DENSE CERAMICS,
Abstract
Conclusions: (1) A notable change in the properties of ceramics both after the action of gamma rays and at the moment of radiation by gamma rays in a weak field brought about by the breakdown in the structure of the material through the effect of the glass phase with the formation of centers of coloration is possible only through radiation with a powerful dose (greater than 1,000,000 r). In this situation the relaxation losses decrease and the losses in conductivity somewhat increase. (2) In the area of powerful fields at the moment of radiation with gamma rays even an insignificant dose of radiation 2.25. 10,000 r) leads to a sharp increase in epsilon and tg delta on account of the strong dependence of the processes of ionization of the gas in the pores of the material in a high-frequency electrical field on the action of an outside ionizer.
