We have studied the absorption and speed of sound
in disperse systems based on aerosil and polypropyleneglycol (PPG-425)
within the range of concentrations from 1 to 10 vol.% and of frequencies
from 5 to 1250 MHz. It is shown that the aerosil particles exist in
the form of clusters; their dimensions have been determined.
