This paper studies the feasibility of preparation superfine carbonization niobium powder materials, using mechanical alloying method (also called high-energy ball milling method) and using niobium-based powder and graphite powder as raw materials. It systematically analyses the influence law of the main ball milling process parameters on the ball milling process and ball milling products. It puts forward the technical ways of adjusting carbonization niobium powder materials density and carries out reducing ...
