Molybdenum crucible has significant mechanical strength and heat resistance, the corrosion resistance in aggressive industrial environments. In its properties, molybdenum has remarkably low coefficients of expansion and a high modulus of elasticity, which enables you to use it for very responsible products. Molybdenum almost doubled compared to tungsten more easily, so that the products made of molybdenum have a greater specific strength (at a temperature of not more than 1370 ° C).
Chemical properties
Molybdenum reacts with hydrochloric acid, with sulfuric acid only at a temperature of 80-100 ° C nitric acid, aqua regia dissolves molybdenum only at a temperature of 100 ° C. Is stable in cold alkaline solutions, but in hot alkaline solutions molybdenum is slowly destroyed. Impurities of carbon, oxygen, silicon, aluminum, nitrogen, iron, sulfur and calcium, phosphorus, which in the technical molebene in hundredths or thousandths of a fraction of a percent, significantly affect the properties of molybdenum. Most of these impurities make molybdenum more fragile. The most harmful of all contaminants is oxygen. If it contains 0.0008-0.004% by volume, low-melting oxides lead to a drastic increase in its fragility and a reduction in its plastic deformation properties, especially in the presence of carbon and nitrogen. With an increasing percentage of oxygen of more than 0.015% molybdenum, pressure is not processed and becomes brittle.

scope of application
Molybdenum crucibles (milled, chopped or welded) are mainly used in metallurgy and mechanical engineering.
They are required for the metallization of lanthanum materials, magnetic material and precious stones and are used both in melting furnaces and in the manufacture of high-temperature devices.

disadvantage
Almost the only downside is the high cost of molybdenum crucibles, since Mo is a metal, is related to the elements, rare earth metals and its pure form is quite heavy.

Production crucibles
Molybdenum crucibles are made from molybdenum high-quality hot-rolled plates by mechanical processing and pressing.
use When melting rare earth metals, molybdenum crucibles are considered to be heat-resistant containers for the needs of metallurgy and mechanical engineering, as well as for the annealing and sintering of powdered raw materials (non-metals and metals) in the reduction atmosphere.
