FIELD: chemistry.
SUBSTANCE: present invention relates to dispersion of fine hydrotalcite particles, as well as to a method for preparation thereof. Dispersion contains 100 pts.wt water and from 0.1 to 100 pts.wt hydrotalcite particles, characterised by average diameter of secondary particles according to measurement by dynamic light scattering in range from 5 to 100 nm. Method of producing hydrotalcite particles includes wet grinding of suspension of hydrotalcite particles, characterised by average diameter of secondary particles from 0.1 to 10 mcm, using balls with diameter from 15 to 300 mcm.
EFFECT: technical result is production of particles with very small mean diameter of secondary particles, as well as obtaining non-precipitating dispersion with excellent transparency.
