Evolution of liquid-phase methods for growing molybdenum single crystals
The evolution of liquid-phase methods for growing molybdenum single crystals is analyzed. It is shown that the methods for growing crystals with a single heating source cannot solve the problem of producing industrial-sized crystals. Super-large molybdenum crystals of various configurations can be produced using the combined plasma induction method. This method is already used for growing single-crystal ingots, as well as single-crystal plates. The monocrystalline quality of the ingots and the preservation of the orientations of the selected crystallographic axes were confirmed by the X-ray method according to Laue. Single crystals of refractory metals with a given orientation have prospects for application in the power optics of high-power lasers.
