FIELD: chemistry.
SUBSTANCE: invention relates to particles of zinc oxide, increasing heat conductivity or electric conductivity. The particles are represented by the following formula (1): ZnMn+ xO1+nx/2 · aH2O (1), where Mn+ stands for a trivalent or tetravalent metal, x and a satisfy the ratio 0.002<x<0.05 and 0≤a<0.5, respectively, n stands for metal valence. The particles are characterised by a content of columnar particles 80% or higher. Also claimed are: method of obtaining the zinc oxide particles, burnt particles (A) and (B), resin compositions (A) and (B).
EFFECT: invention makes it possible to obtain the zinc oxide particles, used for an improvement of electric conductivity or heat conductivity of resins.
