MINERAL POWDER MATERIAL WITH GOOD DISPERSION ABILITY AND USE OF SAID POWDER MINERAL MATERIAL Russian patent published in 2016 - IPC C09C3/04 C09C1/02 C08K3/00 C08K9/04 C04B14/00 D21H17/67 D21H19/38 

FIELD: chemistry.

SUBSTANCE: invention can be used in chemical industry. Method of producing ground mineral material involves wet grinding in aqueous suspension until mineral material has median weighted particle diameter d₅₀ of 0.6-1.5 mqm. At that, is not used appropriate technological agents. Then one performs concentration or dehydration till content of solid product in range of 50-70 %. Suspension is dried to produce mineral materials with content of solid products of 99.8 %. Obtained product is treated with, at least one aliphatic carboxylic acid.

EFFECT: invention allows to improve dispersion of mineral material without using dispersants.
