BiVO4 based high k microwave dielectric materials: a review

The BiVO4 material has attracted much attention in recent years due to its active photocatalytic properties under visible light, bright yellow color as a nontoxic pigment, and its high relative permittivity (ϵr) and Qf (quality factor, Q × resonant frequency, f) as a potential microwave dielectric c...

Description
Summary:The BiVO4 material has attracted much attention in recent years due to its active photocatalytic properties under visible light, bright yellow color as a nontoxic pigment, and its high relative permittivity (ϵr) and Qf (quality factor, Q × resonant frequency, f) as a potential microwave dielectric ceramic. In this review, we introduce the origin, synthesis, crystal structure and phase transitions of the four polymorphic phases of BiVO4: orthorhombic (pucherite), zircon (dreyerite), scheelite monoclinic (clinobisvanite) and scheelite tetragonal. We then precis recent studies on doped BiVO4 ceramics in terms of A site, B site and A/B site complex substitutions. Low sintering temperature (
