    摘要: Ceramic hydroxyapatite material contg. continuous and 2dimensional pores, has continuous passages in the 2-dimensional directions. Passages have dia. 50-1500 microns, and porosity of the material is 20-90%. Prodn. comprises (a) laying up alternating layers of hydroxyapatite and a heat-decomposable net or organic polymer in a laminated state one upon the other in a mould; (b) heat-decomposing and gasifying net material; then (c) firing the plied and moulded body to form porous network. A substitute material for bones in surgery or orthopaedics, filling cavities of bones in dentistry and oral surgery, or producing implant material.
