| Abstract: |
| In this present paper, use the MgO, Al2O3 and SiO2 as the raw material and mixed according to certain proportion, and the mixed raw material by microwave sintering synthetic cordierite-based wave-transparent material, and explore different microwave sintering temperature on the phase, dielectric properties, apparent porosity and bulk density of the samples. The results indicated that: improve microwave sintering temperature favors generate cordierite phase; with increasing temperature of the sample density increases, and dielectric constant increases, while the ceramic material portion spinel collided into cordierite phase, so that the dielectric constant decrease, the dielectric constant is highest at temperature of 1350℃; With the sintering temperature increase, the apparent porosity of the sample decreased, the bulk density increases. |
