In the present study, the effect of temperature and oxidising agents such as Fe2O3and Co3O4on
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 a foaming agent. In the process,
powdered waste glass (mean particle size below 63mm) in addition to 4 wt-% SiC powder (mean
particle size below 45mm) are combined with Fe2O3and Co3O4(0?4, 0?8 and 1?2 wt-%) have
been sintered at 950 and 1050uC. The glass foamed 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 Fe2O3in comparison with samples
without iron oxide, little changes in porosity and strength are obtained.
