Effects of Additives on Crystallization Behavior and Properties of GlassCeramics from Copper Slag Reduction Tailings
The chemical composition of copper slag reduction tailings is similar to that of CaOAl2O3SiO2 glassceramics. The preparation of glassceramics with copper slag reduction tailings as the main raw material by melting method provides an effective way for the efficient utilization of copper slag. The effects of different additives (B2O3, CaF2, TiO2 and Cr2O3) on the phase composition, flexural strength, bulk density, water absorption and apparent porosity of glassceramics were studied by DSC, XRD and SEMEDS. The experimental results show that no matter which additive is added, the glassceramics precipitate anorthite and gehlenite with good mechanical properties, and the crystal crystallization mode transforms into overall crystallization. Adding B2O3 makes the best performance of glassceramics, followed by TiO2 and CaF2.
