Magnetron frequency
GeoffreyF:
Not all microwaves use berylium ceramic but many do. There is no reason not to take apart a microwave and see what is going on but to poo poo precautions is irresponsible.
Richard Crowley:
Remember that if you change the operating frequency too far higher or lower, you will start causing illegal radio interference.
Domestic microwave ovens operate in the 2.4GHz ISM band, and large industrial microwaves in the 915MHz ISM band
ISM = Industrial, Scientific and Medical. There are around a dozen of these frequency spectrum bands where unlicensed use is permitted. The original WiFI, and BlueTooth also operate in the 2.4GHz band. Note that you can't use WiFi or BlueTooth if you are close to a microwave oven. I need to move my kitchen computer farther away from the microwave.

AFAIK, BeO is white and Al2O3 is red (colored with Cr2O3, in essence making it ruby ceramic).

Do you have any evidence to back up this claim?
