Abstract Scope |
Recycling chains of glass wastes were largely developed but some types of glass, polluted with heavy metals, pose a tougher problem. Indeed, glass wastes from the electronics should be treated in a specific recycling process. This is the case of Cathode Ray-Tubes (CRT) found in older-style TV screens and monitors. Glass-foam manufacture is a promising mode for re-using CRT glasses; this cellular material combines low density, low thermal conductivity, excellent thermal stability, and high rigidity. For this work, we focused our attention on the microwave absorption property. Inorganic additives can be used to reinforce this property. Indeed, when Carbon is used as the foaming agent, high dielectric losses are observed. In this work, we studied the impact of the glass cullet and the foaming agent rate on the density and the microwave behavior of glass-foams. The thermal stability and the high-power microwave absorbing application of these foams will be presented. |
