摘要： Use, as a milling agent for milling a suspension, wet dispersing agent or for surface treatment, of a powder comprising more than 90% by mass of sintered balls, each sintered ball having: a chemical composition such that, in percentages by mass based on the mass of the ball: 89%≤W≤97%; 5%≤C≤8%; Co≤0.5%; Ni≤0.5%; Elements other than W, C, Co, and Ni, or “Other elements”: ≤3%; a tungsten carbide(s) content greater than 55% in percentage by mass based on the crystallized phases; a bulk density greater than or equal to 14 g/cm3.
