Summary

Phase equilibria and properties of ceramics in the system BaAl2Si2O8 -BaGa2Ge2O8 were studied. Materials were prepared using solid state synthesis techniques. The phase composition, solidus temperatures, thermal expansion, flexural strength, bulk modulus, and dielectric properties were characterized for partially and fully substituted materials. The changes in the properties of the ceramics were correlated with the degree of substitution.
