New　high-E　and　high-Q　microwave　dielectric　ceramics　(1　-　x)Ca0.6Nd0.26TiO3　-　xNd(Zn0.5Ti0.5)O-3　(x　=　0.00-0.40,　referred　to　as　(1　-　x)CNT　-　xNZT)　were　prepared　by　conventional　solid-state　preparation　route.　Single　orthorhombic　perovskite　phase　was　formed　when　x　was　not　beyond　0.15.　And　a　secondary　phase　Zn2TiO4　appeared　for　x　=　0.20,　while　ZnO　was　the　secondary　phase　for　the　ceramics　with　x　above　0.20.　The　dielectric　constant　and　temperature　coefficient　of　resonant　frequency　decreased　steadily　with　increasing　x-value.　High　Qf-value　of　above　10,000　GHz　was　achieved　as　x　varied　from　0.00　to　0.20.　However,　Qf-value　decreased　rapidly　when　x　was　beyond　0.20.　Some　(1　-　x)CNT-xNZT　ceramics　with　high　epsilon　and　high　Qf　value　were　obtained:　epsilon　=　78.8,　Qf　=　19,200　GHz,　tau(f)　=　+　135　ppm/degrees　C　for　x　=　0.15;　epsilon　=　71.8,　Qf　=　17,300　GHz,　tau(f)　=　+　94　ppm/degrees　C　for　x　=　0.20.　(C)　2009　Elsevier　B.V.　All　rights　reserved.
