A biomaterial comprising a ceramic material, the ceramic material having a plurality of connecting micropores of an average diameter of between 1 .mu.m and 10 .mu.m, substantially evenly distributed through the biomaterial. The ceramic particles are preferably partially fused to one or more adjacent ceramic particles to form a lattice defining micropores. Each particle preferably has an average diameter of 1 .mu.m and 10 .mu.m and may comprise a plurality of elongated macropores having an average diameter of between 150 .mu.m and 500 .mu.m. Further, the material may additionally contain midi-pores which are substantially spherical and have an average diameter of 5 .mu.m and 150 .mu.m. In addition, the application relates to a process for preparing a biomaterial comprising: (i) preparing a mixture of finely-divided biocompatible ceramic particles with a coating agent; (ii) causing the coating agent to coat the ceramic particles to form coated particles; (iii) causing the coated particles to form a body; and (iv) heating the body to eliminate residues of the coating agent, to partially fuse the ceramic particles and produce a fused biomaterial, and to biomaterials obtainable from the process and to the uses of the biomaterials.
