DEVELOPMENT OF A FERRITE MATERIAL FOR A HIGH POWER PHASE SHIFTER AT S-BAND

Abstract

Numerous batches of composition 4 initially were prepared using conventional ceramic methods. The amount of milling, calcining temperature, and firing cycle were varied. Samples from these various treatments were thoroughly evaluated. Several batches of composition 4 were flame sprayed. Fifteen flame sprayed samples were hot pressed in the small hot press. Hot pressing, number 28, yielded a material with loss proper ties similar to TT-414. This was the 'ultra' fine material collected in the water. It is felt that of all the flame sprayed, hot pressed materials this material showed the most promise of meeting the contract specifications. The new hydraulic system was completed on the large hot press and a 6 x 1 x 1/4 inch sample was success fully hot pressed.
