Abstract : A free-space microwave setup has been used to measure the dielectric constant and loss tangent at temperatures up to 850 deg C in the frequency range 8 - 40 GHz for several ceramic materials. The setup and technique are described, and results are presented for both commercially available fired ceramics and a green alumina sample during and after initial binder burnout and firing.
