发明名称 Low oxygen refractory metal powder for powder metallurgy
摘要 Abstract: Process for producing formed Ta/Nb powder metallurgy products using Ta and/or Nb hydride powders with an oxygen content greater than a target level, e.g., 300 ppm, heating the metal hydride in the presence of another metal having a higher affinity for oxygen, removing the other metal and any reaction byproducts, to form a metal powder with an oxygen content less than the target level and forming a metallurgical product from said oxygen reduced Ta/Nb powder with an oxygen content less than the target level.
