A state-of-the-art analysis of the use of ultra fine tungsten metal powder .01 to .1 micron range of particle size in the production of tungsten sheet products was completed. Both the available technology and industry capabilities as related to raw material availability, handling methods, consolidation practices and conversion methods were analyzed. The three major commercial sources of ultra-fine tungsten powder per formed limited experimentation in further consolidation of these powders. Government facilities and private research organizations made limited investigation of the powder, consolidation and fabrication characteristics. The state-of the-art included a discussion of the recrystallization and ductile to brittle transition temperature behavior of sheet produced from conventional tungsten powders the significance of these findings to this program is noted.
