Influence Of Co3O4, Fe2O3 And Sic On Microstructure And Properties Of Glass Foam From Waste Cathode Ray Tube Display Panel

In this study, the effect of temperature and oxidising agents such as Fe2O3 and Co3O4 on physical and mechanical properties of glass foam is investigated. The glass foam is made of panel glass from dismantled cathode ray tubes and SiC as foaming agent. In the process, powdered waste glass (mean particle size below 63 um) in addition to 4 wt-% SiC powder (mean particle size below 45um) are combined with Fe2O3 and Co3O4 (0.4, 0.8 and 1.2 wt-% have been sintered at 950 and 1050 deg C. The glass foam containing 1.2 wt-% Co3O4 has good physical properties, with porosity more than 80% and bending strength more than 1.57±0.12 MPa. However, by adding different amounts of Fe2O3 in comparison with samples without iron oxide, little changes in porosity and strength are obtained.
