dc.description.abstractThis work deals with influence of ceramic processes parameters like moisture, compaction pressure and heating source (electric resistance and hybrid microwave) on dielectric properties of a sintered translucent porcelain. Several porcelain samples were prepared with two levels of moisture (3% and 6%) during the pressing process and two levels of hydraulic pressure (100 and 174 MPa) before drying; porcelain composition was kaolin (43%), potassic feldspar (36%), quartz (17%), bentonite (1%) and wollastonite (3%). Dielectric properties of the green porcelain were measured, and the results induced the use of a hybrid microwave furnace. Dried porcelain samples were sintered at 1200 oC with an electric furnace (7000 W) and with a microwave hybrid furnace (1600 W of microwave with silicon carbide as a susceptor). The dielectric properties of the sintered porcelain were measured. The results were statistically analyzed with Yates' method and variance analysis; it was proved that sintering with microwaves has a significative influence on the dielectric constant and loss tangent with 99.9% of confidence. Compaction pressure level impacted loss tangent value with 99% of confidence and moisture level (at pressing) impacted dielectric constant with 90% of confidence. Multivariate regressions for the green porcelain dielectric constant and loss tangent were determined. © AMPERE 2021. All rights reserved.en
