MoW30-PM CRUCIBLES FROM MOLYBDENUM-TUNGSTEN ALLOY
Use
MoW30 molybdenum-tungsten alloy, strengthened with a solid solution of tungsten, features temperature resistance and creeping resistance that is higher than molybdenum, and higher machinability than tungsten.
MoW30-PM crucibles made from sintered and forged molybdenum-tungsten alloy are used primarily to melt corundum in technologies for growing extremely pure sapphire single crystals.
Chemical composition of crucibles
Molybdenum is the base, with 28–32% tungsten. The alloy may be additionally strengthened with admixtures of B, Hf, Y, Zr, C.
PRODUCTS MADE FROM MOLYBDENUM, TUNGSTEN AND THEIR ALLOYS FOR USE IN HIGH-TEMPERATURE FURNACES
Use

Shape and manner of production
Products are made in sintered form or from deformed (by forging or rolling) stock (sheets, plates, forced products, rods) according to the client’s drawings or according to a manner of production, geometric dimensions and tolerances for dimensions and surface roughness submitted by the client.
Products are made in simple shapes: tooled discs, slabs, rings, plates, substrata, bearing plates, rods, or electrodes; or in complex shapes: thermal screens, radiators, boats, fastening details, etc. Additional requirements regarding product specifications are set based on the client’s request.
Recommendations on use
Before use, thermal screens and other products used in a customer’s vacuum furnaces should be annealed in a vacuum of p<10–4 mmhg (torus) in the following manner:
During use, the products should not be subjected to shocks.
