Molybdenum Target

Overview of molybdenum (Mo) targets

Molybdenum targets, molybdenum is a silver-white metal, with molybdenum atomic radius of 0.14nm, an atomic volume of 235.5px/mol, coordination number 8, the crystal is Az-type body-centered cubic crystal system, the space group is Oh (lm3m), so far it has not been found to have isomeric transformation. The lattice parameters of molybdenum at room temperature are between 0.31467 and 0.31475 nm, varying with the impurity content. The density of molybdenum is 10.23 g/cm, about half that of tungsten (tungsten density 19.36 g/cm). Molybdenum has a very low coefficient of thermal expansion of 4.9 x 10/°C at 20 to 100°C; it has a high thermal conductivity of 142.35 w/(m-k). The resistivity of molybdenum is low: 5.17×-10Ω-cm at 0°C; 24.6×-10Ω-cm at 800°C; 72×-10Ω-cm at 2400°C. 

Molybdenum is a paramagnet, with a specific magnetization coefficient of 0.93×10cm/g at 25°C for 99.99% pure molybdenum. The specific heat of molybdenum is 242. 8J/(kg-k) at 25°C. Molybdenum has a hardness of 5 to 5.5 on the Mohs scale. molybdenum has a heat of evaporation of 594 kJ/mol at the boiling point; a heat of melting of 27.6 ± 2.9 kJ/mol; and a heat of sublimation of 659 kJ/mol at 25°C. molybdenum is a heat emitter and heat shield with superior electrical and thermal conductivity, a small coefficient of thermal expansion, and high resistance to corrosion. it is mainly used in electric vacuum devices, heat emitters in high-temperature furnaces, heat shields, material boats, etc. It is mainly used in electric vacuum devices, heat generators in high-temperature furnaces, heat insulation plates, material boats, etc. It is used in the manufacture of molybdenum boats, molybdenum elements for power semiconductors, and the production of electric vacuum light source parts.

The most important benefit of our molybdenum targets is that they have excellent electrical conductivity and minimal particle size in the physical vapor deposition process. The table below shows a certificate of analysis of the composition of 3N5 molybdenum targets. Analysis methods used: 1, metal element analysis using ICP-OES; 2, gas element analysis using LECO.
