Abstract

The mechanical properties of alumina test bars fabricated using injection moulding as the shaping operation, are described. The modulus of rupture, hardness, fracture toughness and wear behaviour of the ceramic specimens are reported. Test bars were injection moulded using a polypropylene-based high molecular weight organic vehicle. The processing and microstructure of the test bars were discussed in Part I. The alumina powder was selected in a previous investigation, which considered the compounding, compression moulding, removal of organic vehicle and sintering of several formulations containing different alumina powders.
