The dielectric losses are investigated in high-purity grades of silicon doped by different ways to reduce their mm-wave absorption. The results of the dielectric loss tangent measurements are given for the frequency range of 30 - 330 GHz and for the temperature interval 30-330K. The obtained data are discussed together with the thermophysical properties with respect to the power transmission capabilitity of edge-cooled output windows for high power gyrotrons and the potential of the special silicon grades are demonstrated for these applications.
