Latest Patents

Benoît Donazzon holds 2 patents that showcase his expertise. His first patent is a "Method for packaging industrial, in particular radioactive, waste in apatite ceramics." This invention involves a process for the containment of industrial wastes, especially nuclear wastes, in apatite ceramics. The process includes preparing a homogeneous mixture of powders that can form an apatite matrix, introducing the waste into this mixture, compacting it under a pressure of 100 to 500 MPa at room temperature, and subjecting it to hydrothermal processing at low temperatures (100 to 500 °C) in the presence of water in a sealed chamber.

His second patent is titled "Method for making apatite ceramics, in particular for biological use." This process focuses on manufacturing apatite ceramics, especially for biological applications. It involves preparing a homogeneous mixture of powders to form a hydroxyapatite of formula Ca (PO ) (OH), which may be stoichiometric or non-stoichiometric, possibly containing other additives or flaws. The mixture is compacted under a pressure of 100 to 500 MPa at room temperature and subjected to hydrothermal treatment at low temperatures (100 to 500 °C) in the presence of water and in a sealed chamber.
