摘要：

Synthetic hydroxyapatite (HAP) particles were incorporated into ethylene vinyl acetate (EVA) co-polymer and then shaped into various forms by simple plastic-forming techniques. Composites with HAP volume of fraction from 10-60% were prepared and shaped. The shapes thus formed were subjected to thermal debinding and subsequent sintering to 1150 degreesC. Retention of shapes was found after thermal debinding and sintering of composites above 30 vol.% of HAP. (C) 2000 Elsevier Science B.V. All rights reserved.
