Molybdenum boat

Advantages of molybdenum boats

Molybdenum boat differs with mechanical strength, refractory quality, corrosion resistance in aggressive liquid or gaseous environment. Molybdenum boat has high module of elasticity, insignificant thermal coefficient of expansion. These properties allow using molybdenum boats in the most responsible and complex technological manufacturing conditions. Molybdenum boats are more lightweight than tungsten almost twice. That is why molybdenum products have higher strength-to-density ratio (up to a temperature of +1370°С).

Chemical properties

Molybdenum boat reacts with salt, sulfuric acids only at a temperature of 80−100°C. Nitric, chloronitric acids dissolve molybdenum only at a temperature of 100 °C. It is resistant in cold alkali solutions, but it slowly fractures in hot alkali solutions. Additives of carbon, oxygen, silicon, aluminium, nitrogen, iron, sulfur, calcium and phosphorus that are included in commercial molybdenum significantly increase molybdenum properties. The main part of these additives makes molybdenum more brittle. The most detrimental additive is oxygen. If it constitutes 0.0008−0.004%, easy-melting oxides can lead to sharp increase of material brittleness and decrease of metal flow qualities (especially if there are present carbon and nitric). With increasing of oxygen percentage (more than 0.015%), molybdenum becomes brittle and cannot be pressure treated.


Virtually the only one demerit is high self-cost of molybdenum boat, as long as molybdenum relates to rare-earth elements and it is hardly isolated in a pure state. Besides, it is refractory and hardly processed metal.


Molybdenum boat is manufactured out of high-quality molybdenum plates (MCHWP, MCH) with a help of bending, riveting, powder pressing with further mechanical processing. This technique provides high operational reliability and heat resistance. Such boats are available in any shape and size.


Molybdenum boat is broadly used in electrical engineering, growing of single-crystals, recovery of metal oxides, glass melting, in manufacture of ceramics in high-temperature installations with vacuum or hydrogen atmosphere for annealing and baling of powder products made of metals and non-metals.
