Millimeter wave spectroscopy of alumina-zirconia system

It is important to know the dielectric properties of ceramics at high frequency millimeter wave region as the basis of practicing the millimeter wave sintering of ceramics. For this purpose, dielectric measurements by the millimeter wave spectroscopy were done for alumina-zirconia system compact bodies. The measurements were done using tow measuring systems, a BWO millimeter wave spectroscopy system and a millimeter wave vector network analyzer system. As an example of this study, it was obtained that the relationship between the dielectric constant and the alumina/zirconia ratio was almost linear at W-band.
