Dear Colleagues;
Is there anybody have a idea for treating and microwave irradiation of transparent minerals such as silica in multi-mode microwave (like conventional kitchen microwave)? Silica is transparent minerals and microwaves will come back to microwave magnetron which it is harmful in long-term for equipment .
Maybe it is good to use Water or some other liquid medium (NaOH; inside microwave in baker); in this case probably almost microwave energy will be absorbed for warming of water or liquid located inside apparatus and probably there is not significant effect of microwave irradiation on the silica particles or lumps)? Other choice is putting of liquid and solid mixture in a glass plate in microwave for irradiation? What is your idea?
Regards,
Hamed
Dear Hamed, please explain what is your goal and what you mean by transparent mineral - transparent for microwaves or in the optic region?
Hello Vladimir;
Thanks for your comment; When I said transparent minerals it is due to silica response to microwave irradiation; therefore silica is transparent minerals to microwave irradiation and there is not any relation to optic region.
As you know; kitchen microwave is multi-mode and if you use transparent minerals; micro-waves will return to magnetron and will damage it accordingly; what is you idea for treating transparent minerals with micro-waves.

Hamed
Dear Hamed, I think there is no problem at all. All microwave energy generated in the oven is released as heat. The generator, dishes with food form a closed circuit with correspondent resistors Rg+Rd+Rf . The heats that released in the different parts of the circuit are proportional to the resistance values. So if there is no food Rf=0 and the dishes is "transparent" Rd=0 then all the power of the oven goes to heating of the generator and can damage it. That case is always pointed out in the manuals for the oven.
