- 摘要：
FIELD: chemistry. ^ SUBSTANCE: in order to obtain ground mineral material a) at least one mineral material which is optionally in form of aqueous suspension is taken, b) said material is ground, c) the ground material obtained at step (b) is optionally sieved and/or concentrated, d) the ground material obtained at step (b) or (c) is optionally dried. The grinding step (b) is carried out in the presence of zirconium oxide grinding beads containing cerium oxide, having cerium oxide content between 14 and 20% of the total weight of said beads, preferably between 15 and 18% of the total weight of said beads, and more preferably approximately 16% of the total weight of said beads. The average size of grains after sintering grains which form said beads with average diameter less than 1 mcm is preferably less than 0.5 mcm and more preferably less than 0.3 mcm. The obtained ground mineral material is in form of aqueous suspension, wherein the weight ratio ZrO2/CeO2 is equal to 4-6.5, preferably 4.6-5.7 and more pr
