Molybdenum disk

Relevance

There are a lot of advantages that molybdenum disks possess: mechanical strength, refractory quality, low linear expansion thermal coefficient, high module of elasticity, unique corrosion and chemical resistance to the most aggressive reagents. All these qualities make molybdenum disks the indispensable material in the harshest manufacturing conditions. Molybdenum disks are more lightweight than tungsten almost twice. That is why molybdenum products have a higher strength-to-density ratio (at a temperature of not more than 1370°С).

Chemical properties

Molybdenum 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.

Demerits

Virtually the only one demerit is high self-cost of molybdenum disks 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.

Manufacture

Molybdenum disks are manufactured by method of baking, blanking or mechanical processing. Tolerances and sizes must be agreed with customer. Manufacturing technique of disks and characteristics of material provide high operational reliability and thermal resistance. Cost is defined by sized, complexity of configuration and additional customer’s requests.

Application

Molybdenum disks are applied in the capacity of constructional elements in silicon load-bearing semiconductor devices.
