    Abstract:

    In this paper, LaAl1-xGaxO3 powder and its amorphous sphere have been prepared by sol-gel method and containerless solidification technology, respectively. Ga3+is used to substitute Al3+ in B-site with the composition of x from 0 to 1. The X-ray diffraction results show that powders with no impurity phase were obtained when calcined at 850℃ which are all perovskite structure. The transparent spheres are proved to be amorphous by XRD analysis. With the increase of Ga3+ content, the dielectric constant ranges from 15 to 19 at 100KHz and it¢s corresponding dielectric loss is smaller than that of 0.007. The amorphous material has a low leakage current of 10-1A/cm2, and showed a high refractive index, which was more than 1.8 in 633nm.
