Lithium-borate-based glass co-doped with nickel and cobalt ions was successfully fabricated by a two-step melt quenching method. The relationship between Ni and Co contents in the glasses was investigated, with a focus on their electrochemical proper

The excellent giant dielectric properties (ExGDPs) are represented in the isovalent–Zr4+/pentavalent–Ta5+ ions co–doped TiO2 with different co–doping percentages (x%ZrTTO). The dopants were dispersed homogeneously in a highly compact–graine

CaCu3-xNixTi4O12/CaTiO3 ceramic composites were fabricated using initial Ca2Cu2-xNixTi4O12 compositions (x = 0, 0.05, 0.10, and 0.20) to improve the dielectric properties (DPs) of the CaCu3Ti4O12 ceramics. CaCu3Ti4O12 and CaTiO3 phases were confirmed

Low dissipation factor (tanδ) and excellent temperature stability of high dielectric permittivity are obtained in Ti1-x(Co1/3Ta2/3)xO2 ceramics, which were prepared using a mixed oxide method. The unit cell of the rutile TiO2 structure expanded due

A solid–state reaction method was used to produce CaCu3-xMgxTi4O12-2xF2x with x values of 0, 0.05, and 0.10. A CaCu3Ti4O12 phase was detected in the absence of impurities. The (Mg2++F–) co–doping ions inhibited the grain growth of the CaCu3Ti4O

We present a method for increasing the dielectric constant of CaTiO3/CaCu3Ti4O12 (CTO/CCTO) composites and retaining a low-loss tangent (tanδ) by doping with Ge dopant. The Ge-doped CTO/CCTO composites were fabricated using a one-step processing met

An extremely reduced loss tangent while retaining ultrahigh dielectric permittivity can be successfully obtained in La1.9Sr0.1NiO4 ceramics by doping with Mg2+ ions. A single phase of La1.9Sr0.1NiO4 was detected in all the sintered ceramics, while th
