Molybdenum disc has a very high heat resistance and mechanical strength. The melting point of molybdenum 2620 °C refractoriness, it is second only to tungsten, rhenium, osmium, iridiu. Molybdenum retains strength at temperatures up to 2000 °C. To 1370 °with its relative thermal strength is higher than that of tungsten. Molybdenum is characterized by minimum thermal expansion coefficient, high elastic modulus, excellent corrosion resistance, allowing it to be used in the most demanding conditions, including in aggressive environment.
The disadvantage is the high production cost of molybdenum discs. Because of the significant hardness and refractoriness molybdenum difficult technological processing. Production it time-consuming, and obtaining it in its pure form is quite difficult. Under normal conditions, it is rigid and not very technological material.
Molybdenum disc is produced by hot rolling of the billet obtained by powder metallurgy by pressing high-quality MCH and MCIT and subsequent machining. Dimensions and tolerances are agreed with the customer. The latest production technology guarantee the high-temperature resistance and reliability of the molybdenum discs. The price depends on the size, complexity of processing and the additional requirements of delivery.
Disks are an important structural element of the power silicon semiconductor devices.
