FIELD: electricity.
SUBSTANCE: particles of alloyed ZnO are produced by grinding of sintered ZnO unit, by means of grinding or crushing of calcinated granulated particles, or grinding of calcinated or sintered tape (tape-casting). Versions of realisation, inter alia, are related to hollow microvaristor particles of ZnO produced by granulation method, having lower average density and having diametres in the range of much lower than 90 micrometre; and to compounding of ZnO filler in binders used for tape impregnation. Produced tapes are flexible, preferably self-adhesive and have strong non-linear electric resistance. These tapes are useful for protection of areas with high voltage in electric components.
EFFECT: provision of stronger and more reliable non-linear electric resistance, simplified manufacturing of filler from ZnO and mixing with binder.
