Application of Nd (Mg½Ti ½) O3 (NMT) Perovskite in Mobile Communications

The electrical conductivity, phase, and space group of property of the NMT substance and grain boundary of samples were approximated from complex compound by Raman spectroscopy, X-ray, SEM, TEM, and differential scanning calorimeter (DSC), samples prepared and analyzed in the laboratory in the frequency ranges from 9.76 GHz. The solid-state conventional method utilized. All the samples were tested by using XRD from 1250°C to 1550°C by increasing 50 degrees for every sample and cooling to the room temperature. The contraction of structure did not happen even at elevated temperature. The increase in Nd
⁺
ion polarizability is 0.50 nm compared to La
⁺
rare elements material, which is 0.60, this contributes to change of perovskite cubic. This is result of the smaller size of Nd
⁺
0.127 nm cation compared to La
⁺
which increase number of dipoles despite the reduction of diploes and expands relative permittivity (ε
r
). The single-phase material produced which shows quality factor Q×f = 60000 saturated at 10 GHz and temperature coefficient of (τ
f
) = -77 MK
