How to build a Vacuum Crucible with Ceramics ?

01 January 2018 1 2K Report

This is for use in an Microwave Oven. Hence has to withstand approximately 2000o Celsius. Vacuum pump will be connected to the lid of the crucible. Therefore a sealant is also required which would withstand these temperatures.

Any other methods are also welcome :)

Is it not possible to place the microwave oven in a closed box that can be vacuumized? Making seals that survive a 2000 K temperature excursion seems to much like a challenge and will anyway be expensive....
