Refq. Nogueira et al., FABRICATION OF ENGINEERING CERAMICS BY INJECTION-MOLDING A SUSPENSIONWITH OPTIMUM POWDER PROPERTIES .1. PROCESSING AND MICROSTRUCTURE, Journal of Materials Science, 28(15), 1993, pp. 4167-4174
A suspension containing a polypropylene-based high-molecular weight or
ganic vehicle and an alumina powder (which best satisfied criteria for
successful compounding, compression moulding, removal of organic vehi
cle and sintering stages, each necessary for the fabrication of the fi
nal ceramic shape) was further assessed in this investigation. Test ba
rs were injection moulded from this suspension under various condition
s. After removing the organic vehicle, test bars were sintered and the
resulting microstructure studied. The mechanical properties of the te
st bars will be discussed in Part II.
