Abstract: Glass components recovered from dismantled cathode ray tubes (CRTs) are very difficult to recycle or reuse and so other methods of using these glass components must be found to prevent environmental problems. Through the mixing of the recovered glass with calcium carbonate powder, glass foams can be synthesized that have applications in thermal and acoustic insulation. The various effects on the sintering process such as heating rate and holding time of the calcium carbonate powder are investigated. After the results of preliminary thermal conductivity and mechanical testing, the authors have determined that the foams synthesized were approaching commercially available glass foams.
