摘要：
The invention concerns a method for making a glass frit for confining by vitrification a substance comprising at least one oxidizable or reducible chemical species, as well as a method for confining by vitrification said substance. The method for making a glass frit includes a step of incorporating in a raw glass frit an oxidoreduction couple whereof the type and the amount enable said at least one chemical species to be maintained in its oxidized or reduced state. The confining method includes mixing and hot melting the resulting glass frit and the substance to be confined. The invention enables the confinement of pollutants such as radionuclides, metals and metalloids to be optimized. The substance may be nuclear waste or a material derived from incineration of household refuse.
