Foaming of CRT panel glass powder using Na2CO3
Abstract
The recycling of glass from obsolete cathode ray tubes (CRT) has hitherto only occurred to a very limited extent, but the production of foam glass used as an insulation material component has recently been proposed as a promising recycling method. CRT panel glass has high recycling potential due to its non-hazardous composition. Here we report on the foaming of CRT panel glass using Na 2 CO 3 as the foaming agent. We explore how heat treatment temperature and concentration of Na 2 CO 3 affect the density and porosity of the foam glasses, and whether Na 2 O is incorporated in the glass network. The optimum foaming temperature for minimising density and maximising closed porosity is found to be between 1023 and 1123 K. The pore structure depends on the amount of added Na 2 CO 3 , viz, the pores generally become more open with increasing Na 2 CO 3 content. A minimum density of 0·28 g/cm 3 is found when 14 wt% Na 2 CO 3 is added and the heat treatment temperature is 1023 K. Interestingly, the glass transition temperature ( T g ) of the final foam glass decreases linearly with increasing [Na 2 CO 3 ], indicating that the Na 2 O is incorporated into the glass network.
