The refractory metals are extracted from ore concentrates, processed into intermediate chemicals and then reduced to metal. The refractory metals, except for niobium, are produced exclusively as metal powders, which are consolidated by sintering and/or melting. They can be formed, machined, and joined by conventional methods.

A refractory metal (i.e. tungsten) is VPS formed as the cartridge wall structure, with a protective ceramic (i.e., alumina) coating inside and out. The ceramic-refractory-ceramic composite provides environmental protection more » to the refractory metal structure from both chemical attack inside and oxidation outside.

Refractory metals defined The term "refractory metals" is gen-erally applied to metals that have melting points greater than 2000oC (3630oF). Metals in the group are shown in Table 1. Principal materials in the group are tungsten, tantalum, molybdenum, and niobium, all of which are routinely used in the fur-nace industry.
