Abstract:TiO2 based multifunction ceramics are a kind of novel functional ceramics with dual functions of low-voltage varistor and gain-boundary layer capacitor.The low breakdown voltage,high non-linear coefficient and large dielectric constant make the material useful in miniaturized electronic devices as transient high-voltage protectors and surge arrestors.In this paper,the research on TiO2 based multifunction ceramics is reviewed mainly from the viewpoint of the influencing of fabrication process and additives on the multifunction characteristics.Moreover,the future development prospect of the material has been suggested.
Keywords:TiO2 based ceramics  low-voltage varistor  gain-boundary layer capacitor  multifunction characteristics
