Abstract

Strontium-doped barium aluminosilicate ceramics were prepared by the sol-gel and hot-pressing processes. The experimental results show that doped Sr promotes the hexacelsian-to-celsian phase transformation of barium aluminosilicate ceramics. When the mass ratio of Sr increases, the dielectric constant of the samples decreases from 6.03 to 5.37, which is accompanying by the slight increase of tangent loss. These are attributed to the lower polarizability of Sr ion and its oxides. The infrared emissivity presents a tread of first increasing and then decreasing, owing to the effects of doped Sr on crystal structure and phase transformation of barium aluminosilicate ceramics.
