In this paper magnesium carbonate (MgCO3) and titanium-dioxide (TiO2), crystalline modification rutile were used as starting powders.. Process of sintering can be enhanced if mechanical activation precedes. Mechanical activation of the starting mixture was performed by high energy ball milling using ZrO balls and vessels with ball to powder mass ratio 40:1. The observed grinding times were 15, 30, 60 and 120 minutes. The isothermal sintering of compacted powders was conducted at 1100C during 30, 60 and 180 minutes. For specimens synthesized in such a manner, microwave dielectric properties were measured, quality factor Q, specific electrical resistivity (ρ) and the dielectric constant (εr).
