“…Figure demonstrates single‐phase ceramics in the LMTO ternary system. Dielectric properties of these ceramics are listed in Table . Except TiO 2 , they have dielectric constants (at microwave frequencies) ranging from 17 to 27.…”

Sintering behavior and microwave dielectric properties of MgTiO3 obtained from coprecipitation method with additives

“…As mentioned above, MgTiO 3 in multilayer microwave applications must be co‐fired with electrodes with low melting points, therefore, a decrease in sintering temperature is essential. For this purpose, different additives, such as V 2 O 5 , Li 2 O, ZnO, WO 3 , and B 2 O 3 , have been used . It was found that with the addition of B 2 O 3 , the sintering temperature of MgTiO 3 matrix decreased to less than 1200⁰C and dielectric properties were improved (ε r =17.6, Q×f = 33756 GHz ).…”

In another work, Cheng‐Liang Huang et al investigated the effects of ZnO addition on microstructure, phase formation, and microwave dielectric properties of MgTiO 3 –CaTiO 3 ceramics.…”

Microwave dielectric properties of Mg2TiO4 ceramics synthesized via high energy ball milling method

“…The two magnesium titanates are good candidates for use in microwave dielectrics: MgTiO 3 (e c = 13-17, Q Â f = 80,000-200,000 GHz) [2][3][4][5][6]10,11], Mg 2 TiO 4 (e c = 13-14, Q Â f = 150,000 GHz) [7][8][9]. There were a number of methods to synthesize MgTiO 3 ceramics, such as solid state reaction [2], sol-gel [12,13], and chemical-reactive precipitation methods [14]. The possibility of using materials based on MgTiO 3 in the low-temperature cofired ceramic (LTCC) technique has been reported [2][3][4][5][6][12][13][14].…”

However, the available literatures contain seldom data about the synthesis and properties of MgO-TiO 2 dielectric materials based on Mg 2 TiO 4 .…”
