FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing magnesium hydroxide. Method of producing material containing magnesium hydroxide involves hydration of material containing magnesium oxide, its drying and grinding. Material containing magnesium oxide has a specific surface area of 0.1–25 m2/g. In material containing magnesium hydroxide, content of impurities is 0.5–20 %. Dried material containing magnesium hydroxide contains particles with size d50 making 0.5–35 μm with specific surface area of 1.0–20 m2/g.
EFFECT: obtaining material containing magnesium hydroxide, suitable for mixing with polymers.
