“…With the ratio MgTiO 3 :Ca 0.8 Sr 0.2 TiO 3 = 94:6, a dielectric constant (ε r ) of 21.42, a Q×f value of 83,700GHz at 9GHz and a temperature coefficient (τ f ) of -1.8×10 −6 /°C were obtained for 0.94MgTiO 3 -0.06Ca 0.8 Sr 0.2 TiO 3 sintered at 1300°C for 4h [12]. A near-zero temperature coefficient of resonant frequency was measured for 0.79Mg 0.95 Zn 0.05 TiO 3 -0.21(Ca 0.6 La 0.8/3 )TiO 3 ceramics sintered at 1275°C [13].…”

“…(12)- (13) and k are determined, the quality factor of the multiphase mixture could be calculated. In practice, most reports are actually mixing two ceramics to form multiphase ceramics [7][8][9][10][11][12][13]. Even more than two ceramics mixing can be calculated by the same rule.…”

“…In practice, ceramics are always needed to be mixed to form multiphase mixtures to stabilize the work frequency, in other words, to obtain a ceramic with a zero temperature coefficient at the resonant frequency [2,[7][8][9][10][11][12][13]. While the composites' dielectric constant can be well predicted by the Maxwell-Wagner formula, the issue of the quality factor calculation has not been well solved yet [3,[14][15][16].…”

“…This increase might be due to greater value of susceptibility of Cobalt than Zinc [79].The degradation of Q Â f r value can be attributed to the decrease of density resulted from the inhomogeneous grain growth as well as the evaporation of Zn [80].…”
