Lithium aluminate and lithium metasilicate powders compacted to 82% of theoretical density by hot pressing at 119,000 psi and at either 500 or 800/sup 0/C were well bonded. The same powders pressed at room temperature at 119,000 psi had densities of 75 to 77%, and were not bonded. Lithium aluminate powders pneumatically impacted at 800 and 1200/sup 0/C under pressures from 115,000 psi to 350,000 psi were well bonded. Approximately 97% of theoretical density was attained at 345,000 psi and 1200/sup 0/C. Relationships between compacted density and punch pressure, or energy, are plotted.
