Low-temperature firing and microwave dielectric properties of LBS glass-added Li2ZnTi3O8 ceramics with TiO2

Low-temperature Sintering of Bi2O3-B2O3 Glass Doped Li2ZnTi3O8 - Li2TiO3 Ceramic and Its Dielectric Properties

“…The microwave dielectric loss can be attributed to not only intrinsic factors but also extrinsic factors such as second phases, oxygen vacancies, grain sizes and densification or porosity. [18][19][20] Therefore, the decrease of Q×f value is probably caused by the amount of trapped porosity and abnormal grain growth, which can be demonstrated by the SEM images, shown in Fig. 2.…”

“…Therefore, this ceramic has been widely considered as a promising candidate for LTCC in the last decade. [9][10][11][12][13][14][15][16][17][18][19] George et al lowered the sintering temperature of the Li2ZnTi3O8 materials by adding LMZBS glass. 10 Chen et al investigated the microwave dielectric properties of BaCu(B2O5)-added Li2ZnTi3O8 ceramics.…”

“…In order to tune the τƒ value to zero ppm/℃, TiO2-added Li2ZnTi3O8 ceramics with glass addition was investigated by Hou et al and Chen et al. 18,19 Moreover, the effects of TiO2 ratio on the phase composition and microwave dielectric properties of Li2ZnTi3+xO8+2x ceramics were also studied by Li et al, and the τƒ value could be modified to near zero ppm/℃. 20 More recently, Li2ZnTi3O8-Li2TiO3 ceramic was investigated by Wu et al.…”

Synthesis and characterization of Li2Zn0.6Cu0.4Ti3O8 anode material via a sol-gel method

“…In recent years, three kinds of strategies such as particle size reducing [7,[10][11], surface coating [6,[12][13] and lattice doping [14][15][16][17] have been developed to improve the electrochemical performance of Ti-based anode material. Reducing particle size can shorten the diffusion path of Li + and facilitate anode materials contact with the electrolyte fully, thus improving its initial discharge capacity.…”

Role of Nano‐ and Micron‐Sized Particles of TiO2 Additive on Microwave Dielectric Properties of Li2ZnTi3O8 – 4 wt% TiO2 Ceramics

“…Hence, it should be shifted to near zero while maintaining high permittivity and quality factor. Generally, there are two methods to produce a material with a stable temperature coefficient: (i) Composite materials by mixing component materials with negative and positive τ f values, such as Zn 2 TiO 4 –TiO 2 , Li 2 ZnTi 3 O 8 –TiO 2 . (ii) Formation of solid solutions, such as complex perovskite .…”
