Abstract

The paper presents a microwave based-nonconventional technique of manufacturing a cellular glass obtained by a heat treatment at 803 C of a powder mixture composed of glass waste from cathode ray tube (93 wt.%), MnO2 (7 wt.%) as a foaming agent and water addition (10 wt.%). The cellular glass has excellent characteristics as an insulating material: apparent density of 0.19 g/cm3, porosity of 91.4%, thermal conductivity of 0.043 W/m·K and an acceptable compressive strength of 1.17 MPa. An economical specific energy consumption (1.16 kWh/kg) was obtained.
