Relationships between Zr substitution for Ti and microwave dielectric properties in Mg(ZrxTi1−x)O3 ceramics

Correlation between Sn substitution for Ti and Microwave Dielectric Properties of Magnesium Titanate Ceramics

“…In 2008 and 2009, they reported the improvement of properties with M 4+ (M=Zr or Sn) at the B‐site of MgTiO 3 . But few studies were carried out to reveal the relationship between B‐site substitution and the performance in MgTiO 3 ceramics …”

“…, indicating that the crystal volume increased, due to the ionic radius of Sn 4+ (0.69 Å), which is larger than that of Ti 4+ (0.605 Å) when the coordination number is six . The similar result was found in the Zr‐substituted MgTiO 3 systems . The tolerance factor ( t ) was introduced into prediction of ABO 3 ‐type ilmenite formation by Liu, as expressed by Eq.…”

Low-loss microwave dielectric ceramics in the (Co1−xZnx)TiO3 (x=0–0.1) system

“…In addition to the need for new dielectric materials, it is also desirable to promote the dielectric properties of currently available materials through appropriate modifications [7][8][9]. A recent study on the microwave dielectric properties of ATiO 3 (A = Ni, Mg, Co, Mn) ceramics was reported by Kim et al [10,11].…”

Microwave Dielectric Properties of (Ca0.2Sr0.8)3(Zr0.1Ti0.9)2O7 Ceramics

“…Several investigations have been made to improve the dielectric properties, such as the partial replacement of B-site and selection of a compensator in the ceramic systems [6,7]. Tseng et al reported that Zr substitution effectively improved the microwave dielectric properties of MgTiO 3 ceramics [8]. This research prompts us to investigate Zr substitution effect on sintering behavior and microwave dielectric properties of (Ca 0.2 Sr 0.8 ) 3 Ti 2 O 7 ceramics.…”
