Abstract
In this paper, Al2O3-Bi2O3was choosed as chip fuse matrix material. Composition of Al2O3-Bi2O3ceramics samples in different sintering temperature was studied by X-ray diffraction, and dielectric properties of samples under different frequency was measured. The results show that the mixture of Bi2O3in Al2O3ceramics can improve the sintering activity of Al2O3ceramics, and thus greatly reduced the ceramic sintering temperature. It is concluded that the main crystalline phase is pure α-Al2O3without miscellaneous phase distribution. The distribution of fracture morphology is uniform without the existence of apparent stomatal, the dielectric constant and dielectric loss was studied.
