Abstract Scope Lithium hydride is the lightest binary compound with versatile application in nuclear reactor technology, hydrogen storage, and thermal energy storage. Although ceramic lithium hydride has historically been manufactured through casting processes, uniaxial pressing of lithium hydride offers fabrication of material with tailorable properties via microstructure control which can lead to the expansion in application of lithium hydride. Full densification of lithium hydride was achieved at temperatures between 150 – 500 C and a pressure range of 10 – 288 MPa. By varying pressure, dwell time and powder load at 150 C, densities relevant to applications requiring a specific level of density were acquired. Of note, the densification of lithium hydride is highly dependent on powder load. Microscopy revealed lithium hydride powder to be an agglomeration of fine particles, and grain formation (10 μm) and elimination of porosity are observed after sintering. Prepared by LLNL under Contract DE-AC52-07NA27344.
