Particle Aerosol Deposition and the Development of High Temperature Dielectric Ceramics

Lead Research Organisation: University of Leeds
Department Name: Chemical and Process Engineering


Aims. Investigation of a particle aerosol deposition manufacturing route to develop high temperature dielectric ceramics based on alkaline earth niobates with the tungsten bronze crystal structure.
Objectives. Synthesise and analyse a range of compositions of doped, fully dense CBN by aerosol deposition
Characterise microstructure using electron microscopy
Characterise crystal phase content using X-ray diffraction
Characterise dielectric propertiesd
Correlate aerosol deposition conditions to structure and properties of the deposited thick films
Understand the critical parameters controlling structure and properties
Use the emerging knowledge to design a process whereby dielectrics can be produced with stable
relative permittivity and low dielectric loss across the temperature range -55degreesC to 250degreesC and 300degreesC.
