Abstract

 The two steps sintering process provide economical, technological and innovative advantageous aspects to produce biocomposite foams for alloplastic bone grafts applications. The kinetic window mechanism, working during the 2nd TSS step, provides the nanostructured ceramic matrix, respectively improved biocompatibility. Simultaneously, the high porous structure, fitting the trabecular bone tissue, remained an important technical request of such applications up to this research. The porous biocomposite scaffold could be designed using specific foaming agents, like titanium hydride, calcium carbonate and ammonium bicarbonate, by controlling the foaming reactions depending on the foaming agents’ type and content into the chemical composition of the initial biocomposite powder mixture. The new concept of foaming window, working during the 1st TSS step, includes these factors able to provide the specific foam structure fitting the required biocomposite foams porosity. Both windows may work for the benefit of the nanostructured highly porous biocomposite manufacturing by TSS process, in advantageous technical and economical terms.
