Abstract


Metallurgical slag and waste TV glass hawe been used for fabrication of ceramic-glass composite with a controlled porosity. A dense composite consisted of 70 wt% slag and 30 wt% TV glass sintered at 1000 ºC/2h, with the integral porosity of 16 %, has the E–modulus and bending strength of 26.0±1.6 GPa and 60.8±1.9 MPa, respectively. Slag with granulation of 0.125÷0.063 mm and 20 wt% TV glass, sintered at 950 ºC/2h possesses integral porosity of 37 % and E-modulus and bending strength of 11.86±2 GPa and 23.14±2 MPa, respectively, while the composite with the same composition but with porosity of 65 % possesses E-modulus of 2.1±0.3 GPa and bending strength of 3.0±0.4 MPa. The technical coefficient of thermal expansion of the porous systems is 11.12⋅10–6/ºC. The porous composites have been in thermal equilibrium and acted stable in aggressive media.
