Curiousity : What will happen if i use 'microwave oven' instead of ultrasonicator for SiO2 particles suspended in a solvent to prevent aggromeration ?

just a curious question .Will the freq & power in the oven agitate the particles enough to separate them ? since Oven have more power than ultrasonicator what could go wrong ?
