    Abstract: In a method of making alloy of tungsten and lanthana, lanthanum hydroxide is blended with tungsten metal powder, the mixture is pressed to form a pressed ingot, optionally presintered, and sintered to form the alloy. The use of lanthanum hydroxide as the source of the lanthana dopant allows the pressed or presintered ingots to be stored in air prior to sintering for prolonged periods without becoming degraded from exposure to atmospheric moisture.
