Molybdenum Pressed and Sintered Parts

GTP’s pressed and sintered molybdenum is a hydrogen-reduced powder consolidated to a high density. It is designed either to serve as stock for forging, rolling and extruding, or as finished components for specialized applications. A chemically purified ammonium molybdate is converted to molybdenum dioxide, reduced to molybdenum powder, consolidated by isostatic pressing*, and sintered in pure hydrogen to a density exceeding 94% of the theoretical density of 10.22 g/cm3. The common shapes are cylinders, slabs, bars, rings, and tubes. The metallurgographic structures are fine-grained and equiaxed. GTP also manufactures mechanically pressed, hydrogen-sintered molybdenum parts, which are generally smaller pieces requiring closer dimension tolerances.

GTP’s pressed and sintered molybdenum has a minimum density of 9.6 g/cm3, which is 94% of the theoretical density of 10.22 g/cm3.

Molybdenum is the most commonly used refractory metal for high temperature applications. It is also useful for heat shields in high-temperature furnaces, where the temperature is not high enough to require tantalum or tungsten, which are more costly. Molybdenum melts at 2620 °C (4750 °F) and has useful strength up to about 1650 °C (3000 °F). Molybdenum maintains good corrosion resistance in non-oxidizing wet or dry reducing atmospheres. Molybdenum is excellent for use in contact with molten glasses. It should be considered for any unusual non-oxidizing chemical environments at low and at high temperatures as it works efficiently in both instances.
