Process for the production of single- or multi-phase materials of biological interest

Abstract

An integrated solid body of biological interest is produced by admixing a mineral powder with a biologically active principle, and then subjecting the mixture thus obtained to a shockwave thereby to produce an integrated solid body. The shockwave is generated by explosion or by launching a projectile toward the mixture. The mixture is confined in a mold cavity prior to application of the shockwave. The mold cavity is placed under vacuum prior to application of the shockwave. Particles of the mixture are thus cold bonded to each other. The body is in the form of an implant for the human body. The mineral powder is a calcium phosphate, e.g. octocalcium phosphate, dicalcium phosphate, dihydrated dicalcium phosphate, tricalcium phosphate and tetracalcium phosphate.
