Vessels of molybdenum have also been used for such applications as processing nuclear fuel pellets at temperatures up to 1650 C (3000 F), and molybdenum crucibles are durable and will withstand repeated rough handling. In air or oxygen-containing atmospheres, molybdenum is not oxidized to any considerable degree at temperatures below 400 C (750 F).
So incorrect Ramp levels can definitely cause crucible cracking. The second reason is much easier - the user shuts the power supply off or has a very short ramp down time for power after the deposition is done. This causes the rapid solidification of the melt, and this stresses out the crucible liner.

Molybdenum has extremely good resistance to corrosion by numerous acids, liquid metals and molten glass, provided oxidizing agents are not present. Molybdenum is relatively inert in hydrogen, ammonia, and nitrogen up to about 1100°C. TAG: Molybdenum-Crucible
It is widely used in the industry of molybdenum crucible manufacturing. The process of welding molybdenum crucible is to roll the molybdenum sheet into tube, then proceed to welding, after adjust the tube wall, then weld molybdenum circular plate at one end of the molybdenum tube. Because of the lower cost, large size tolerance and poor
