摘要：
The possibility of using quartz-feldspar rocks from Karelia for the production of electrotechnical ceramics is demonstrated. It is established that sintered samples of alkaline sienite have low dielectric losses (0.25) and a dielectric permeability equal to 6.5. The volcanogenic rocks (quartz porphyry with a high content of quartz and microcline) decrease the dielectric permeability of the samples to 5,4 and the dielectric permeability of potassium halleflinta is equal to that of pegmatite, i.e., 7.7.
