Abstract
Foam glass-ceramic with high mechanical strength property was synthesized from waste CRT panel glass by using one-step sintering technology. This product contains columnar crystals in their microstructure and the crystal phases consist of Sr5(PO4)3F and Pb3(PO4)2. The content of additive agents and heating program on the bulk density and the compressive strength were evaluated. Physical properties of sintered material was measured, including the compressive strength 3.42 MPa, the density 0.78 g/cm3, the water absorption 0.41 wt.% and the thermal conductivity 0.052 w/m2·k. The results show that the CRT glass is susceptible to be used for high-performance foam glass-ceramic as building materials.
