“…For the (Li0.5Ln0.5)WO4 system, compositions with ionic radius large than Gd 3+ crystallize in the scheelite structure but only (Li0.5Sm0.5)WO4 and (Li0.5Nd0.5)WO4 are reported as microwave dielectrics. 120,121,134,135 Chen et al 136,137 studied the microwave dielectric properties of (1-x)BiVO4-x(Li0.5Sm0. members with opposite TCF.…”

“…One of the most effective and widely used methods for obtaining a zero temperature coefficient is to combine two phases with τ f of opposite signs via

{normalτ}_{f} = false(1 - x false) {normalτ}_{f_{1}} + x {normalτ}_{f_{2}},

where x denotes volume molar ratios and

τ_{f_{1}}

and

τ_{f_{2}}

have opposite signs . Most of the reported τ f results fit well with Equation while the variation of the dielectric constant and quality factor always depends on whether the solid solution is formed or not . If two phases coexist, the Q×f can usually be easily predicted as in Refs.…”

“…However, most ceramics inherently possess non‐zero temperature coefficients . Thus, wide studies in recent decades of adjusting temperature coefficients to zero have been performed in high dielectric constant ceramics, for example, CaTiO 3 , BiVO 4 , and Ba 6‐3 x Nd 8+2 x Ti 18 O 54 ‐based ceramics …”

Microwave dielectric properties of (1‐x)Ba_3.75Nd_9.5Cr_0.25Nb_0.25Ti_17.5O₅₄–xNdAlO₃ ceramics

This study presents the microwave dielectric properties calculation of (1-x)Ba 3.75 Nd 9.5 Cr 0.25 Nb 0.25 Ti 17.5 O 54 -xNdAlO 3 ceramics where x denotes the volume molar fraction. From X-ray diffraction results, the solid solution limit is calculated to be about 0.76, where it forms a single BaNd 2 Ti 4 O 12 phase in Region I (0 ≤ x ≤ 0.76), and both BaNd 2 Ti 4 O 12 and NdAlO 3 coexist in Region II (0.76 < x < 1). The solid solution limit is confirmed by independently calculating it from the dielectric constant data. There is less than 4 % deviation between the measured dielectric constant (ε r ) and the one calculated from the Maxwell-Wagner formula. The total quality factor (Q) remains almost constant in Region I and increases rapidly with the volume molar fraction of NdAlO 3 in Region II. The measured Q×f, where f is the resonant frequency, is also consistent with the calculated value in both regions. The temperature coefficient at the resonant frequency is -1.4 ppm/ o C, which agrees well with the calculated value of 0 ppm/ o C. In addition, we observed a close correlation between the bulk density and the phase evolution.
