| Summary: | Solid additives are widely used to control the mechanical properties of powders materials in many industries. In this paper, the measurement of the tensile strength of a powder bed with a split-cell type tester was conducted to elucidate the effect of solid additives on the mechanical properties of powders. Fused alumina powder, silica sand, limestone, lactose and potato starch were selected as the powders. Furthermore, colloidal silica was used as a solid additive. The relationship between the tensile strength and the porosity of a powder bed containing the additive was proposed to characterize the effect of additives on the mechanical properties of the powders. Furthermore, the experimental results reported by others were able to be explained by the above relationship.† This report was originally printed in J. Soc.
