Oxide Removal – Microwave 'Turntable' vs Chaos/Randomization

[Anonymous]

In a recent LPP progress report, they were mentioning the use of microwaves as a simple way to remove oxides, but said this might result in uneven oxide removal, since there is no way to include a microwave oven turntable.

Don’t a lot of newer microwave ovens have some sort of “Chaos” feature that randomizes the microwaves to even everything out?

It’s supposed to compensate for the lack of a turntable.

Why not try something like that?

Oxide removal with microwaves should be part of “bake out”. Unfortunately, the mode shapes can be changed via a mixer, but not infinitely. If possible, a side loop of glass tubing to the vacuum pump could be coated with a ‘getter’ metal via induction evaporation, following draw down. Any oxygen released during bake or firing may be absorbed.
