SINTERED BALLS MADE OF TUNGSTEN CARBIDE
다음을 갖는 소결된 볼: - 볼의 중량을 기준으로 한 중량 백분율로, 하기 화학 조성: - 89% W ≤ 97%; - 5% ≤ C ≤ 8%; - Co ≤ 0.5%; - Ni ≤ 0.5%; - W, C, Co 및 Ni 이외의 원소, 또는 "기타 원소": ≤ 3%; - 결정화된 상을 기준으로 하여, 55 중량% 초과, 바람직하게는 80 중량% 초과의 텅스텐 카바이드 함량; - 14 g/cm3이상의 겉보기 질량 밀도.
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.
