Data on plasma spray parameters are given for 108 samples sprayed during this quarter. A new holding furnace and solenoid activated controls for sample translation are the major equipment changes that have been carried out this quarter. Several different ferrite powders and a number of dielectric compositions were investigated. Cracks in the ferrite layer, although reduced in number, are found in most samples.
