分别采用四种不同粒度的钨粉(1.84μm、2.23μm、3μm、4.18μm),以不同的比例进行搭配,充分混合均匀后进行压制、烧结(2300℃),采用排水法测量烧结体密度,采
Four tungsten powders with different particle sizes (1.84μm, 2.23μm, 3μm, 4.18μm) were used, matched in different proportions, fully mixed, and then pressed and sintered (2300℃). The density of the sintered body was measured by the drainage method.
