The foaming mechanism of glass foams prepared from the mixture of Mn3O4, carbon and CRT panel glass
Abstract
<p>Cathode ray tube (CRT) panel glass is processed into glass foams by using carbon and Mn<sub>3</sub>O<sub>4</sub> as foaming agents. We investigate the foaming ability and foaming mechanism of the mixture by varying the composition and the temperature. Carbon load of 5 wt% inhibits the sintering of the glass powder, while 2 wt% carbon promotes the coalescence of pores during foaming. Carbon load of ≤0.4 wt% is suitable for achieving low density foams (0.15–0.23 g cm<sup>-3</sup>) with closed pores (75–100%). Foaming is initiated by the reaction between carbon and Mn<sub>3</sub>O<sub>4</sub> and this is the main source of melt expansion. Reduction of cations in the glass melt, including Mn<sup>3+</sup> dissolved from Mn<sub>3</sub>O<sub>4</sub>, makes an important contribution to the melt foaming at >800 °C. The main gaseous product is CO<sub>2</sub> (67–95 vol%). CO appears above 800 °C and the concentration increases with temperature.</p>
