Abstract:

Nonmagnetic Li-Ti ferrite dielectrics have been processed, fired and ground to final dimensions in preparation for arc plasma spraying APS. Thermal expansion data are given on a series of compositions with variations in alumina content. The ferrite powder to be used for APS coating has been examined by SEM and X-ray fluorescent analysis. We report data on microwave and other properties of a series of phase shifter elements produced at USAECOM laboratories. Different firing schedules were investigated to determine the optimum trade-off in properties. Work is nearing completion on design and construction of APS equipment which will allow a series of samples to be sprayed and immediately fired according to the required schedule. Author
