Summary

Single phase Ti5Si3 was synthesized by SHS and arc-melting of elemental powders. The synthesized powders were ground and classified to < 20 μm. After sintering at 1800°C or 1900°C, in an argon atmosphere, the densities were found to be similar for both SHS and arc-melted materials. However, when the form of the reactants for arc-melting were changed from powders to solid lumps, lower sintered densities were obtained. The difference in sintered densities was attributed to the oxygen content. To support this hypothesis, Ti5Si3 was intentionally doped with oxygen and sintered under identical conditions. Ti5Si3 doped with oxygen had the highest sintered density among all the samples investigated.
