Technical characteristics
Molybdenum is a refractory metal of light-grey color. This is the 42nd element of chemical table, where it is designated as Mo. Density constitutes 10.2 g/cm³, boiling temperature is 4630 °C, and melting point is 2620 °C. Molybdenum powder is a highly-dispersed mass than contains not less than 99.169% of Mo. It is used in the capacity of alloying component and catalytic material for manufacture of semi-conductive supportings, manufacture of lightning equipment, for spaying on a surface etc.

Manufacture
Grade MPH manufactured in accordance with technical conditions 48−19−316−80 is the most requested molybdenum powder. This powder grade contains not less than 99.5% of Mo, 92% of which are smaller than 5 µm.
Application
Molybdenum powder is requested in the capacity of feedstock for manufacture of compacted metal. The billets are formed with a help of powder metallurgy. They serve as the blankets for manufacture of sheets, wire, bars. Advantages of molybdenum allow to widely using it as an alloying component.

* A quantity of additives is given in permil of percent. Such gas-forming additives as O, N, C, S, H, Cl, F are not counted when evaluating molybdenum part.
** ∑Ме — additives of metals totalled up.
The main advantages of molybdenum
— possesses high heat resistance and melting point;
— its density is 10.2 g/m3 (almost twice smaller than tungsten). Due to this, alloys on molybdenum basis are in the lead by strength-to-density ratio at a temperature of up to 1370 °C.
— high module of elasticity;
— minimal coefficient of linear temperature expansion;
— has low thermal-neutrons capture cross-section;
— resistance to solutions of alkalis, salt, sulfuric, fluorhydric acids of different concentrations.
Demerits
— high brittleness of welding seams;
— low plasticity at low temperature;
— low hammer scale;
— hardening of molybdenum by autofrettage is possible only up to 800 °C. Higher temperature leads to softening.
