基　　金：Directorate of Science and Technology (DOST) under itsdevelopmental scheme 'Promotion and Support of R&D in Public & Private Sector, Phase 1 in Khyber Pakhtunhwa (R&D)' Funded Project 2011–2012 Peshawar, Pakistan 摘　　要：All the compositions in the(1-x)Mg_(0.95)Ni_(0.05)Ti_(0.98)Zr_(0.02)O_3–xCa_(0.6)La_(0.8/3)TiO_3(0 ≤ x ≤ 0.2) series were fabricated using solid state sintering route. Mg_(0.95)Ni_(0.05)Ti_(0.98)Zr_(0.02)O_3 possessed excellent microwave dielectric properties with ε_r ≈ 17.1, Q_uf_0 ≈ 195855 GHz, and τ_f ≈-46 ppm/℃. t f was tuned through zero by mixing with Ca_(0.6)La_(0.8/3)TiO_3. In the present study, τ_f ≈-2 ppm/℃ with er ≈ 23.9 and high Q_uf_0 ≈ 115870 GHz was achieved for x = 0.15, i.e., for a mixture of 85% Mg_(0.95)Ni_(0.05)Ti_(0.98)Zr_(0.02)O_3–xCa_(0.6)La_(0.8/3)TiO_3. 关键词：PHASE MICROSTRUCTURE DENSITY ilmenite structure
