What are Refractory Metals - PickPM

Refractory metals are extracted from ore concentrates, processed into chemicals and then into powders. The powders are consolidated into finished products or mill shapes and ingots for further processing. Because of their high melting points and ease of oxidation, refractory metals are usually worked in powder form.
