Abstract: There is provided a flat plate-like sintered tungsten alloy that can be molded into a complex shape by press working or forge processing. The flat plate-like sintered tungsten alloy contains 85% by mass or more and 98% by mass or less of W, 1.4% by mass or more and 11% by mass or less of Ni, and 0.6% by mass or more and 6% by mass or less of at least one substance selected from the group consisting of Fe, Cu and Co, wherein an elongation percentage of the flat plate-like sintered tungsten alloy in a planar direction is 20% or more.

Abstract: A tungsten electrode material contains a tungsten-based material and oxide particles dispersed in the tungsten-based material. The oxide particles are composed of an oxide solid solution in which a Zr oxide and/or an Hf oxide and an oxide of at least one rare earth selected from the group consisting of Sc, Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu are dissolved as a solid solution. A content of the rare-earth oxide with respect to a total amount of the Zr oxide and/or the Hf oxide and the rare-earth oxide is not lower than 66 mol % and not higher than 97 mol %, a content of the oxide solid solution is not lower than 0.5 mass % and not higher than 9 mass %, and the remainder is composed substantially of tungsten.
