Document Type and Number:
WIPO Patent Application WO/2022/138156
Kind Code:
A1
Abstract:
This tungsten-containing powder is configured such that if the FSSS average particle diameter obtained by the FSSS method is "a" (μm) and the density TD, which is the reciprocal of the tap volume of tungsten-containing powder, is ρ (g/cm3), the relational expression of ρ ≥ 0.37a + 7.04 is satisfied when the FSSS average particle diameter "a" is within a range of 0.5 μm ≤ a ≤ 5.0 μm.
