The phase transition, microstructure and microwave dielectric properties were systematically investigated in TiO2 modified MgZrNb2O8 ceramics. The X-ray diffraction and Raman spectrum revealed four distinct phase regions from wolframite, ixiolite, ixiolite–rutile mixture to rutile with increasing the TiO2 content. This phase transition was considered as a result of the destruction of the ordered array...
A novel low-loss microwave dielectric material MgZrNb 2 O 8 was reported for the first time. Single-phase MgZrNb 2 O 8 was prepared by a conventional mixed-oxide route and sintered in the temperature range of 1280–1360°C. The microstructure and microwave dielectric properties were investigated systematically. The X-ray diffraction results showed that all samples exhibit...
