The work describes the processing of dense boron suboxide by hot pressing. Sound billets four inches diameter by three-eights inch thick were consolidated to a density as high as 99.2 of theoretical. Adjustment of process parameters was very critical as incorrect parameters resulted in either low density, excessive decomposition, or cracked billets. Several process modifications were identified that reduced production costs.
