FIELD: process engineering.
SUBSTANCE: invention relates to grinding and may be used for production of arcing electric contacts. Proposed method comprises chemical deposition solution of silver and zinc nitrates, filtration, rinsing and annealing of precipitate. Note here that water-soluble surface-active poly(vinylpirrolidone) in amount of 1 to 3% of total volume of solution is added to solution of nitrates.
EFFECT: higher dispersity and homogeneity.
