Stone-cast matrix based on alloy of basalt and metal oxides. Part II. Basalt–ZrO<sub>2</sub> system
Phase formation in stone-cast matrices (SCMs) obtained as a result of the interaction of molten basalt with ZrO2at 1623 K for 5 h on air was studied. Basalt melted under the above conditions contains two spinels (relict and newly formed), clinopyroxene of the composition Mg0.66Ca0.60Fe0.26Ti0.05Al0.66Si1.80O6, and glass as the main phases. When basalt is fused with ZrO2, taken in a mass ratio of 1 : 1, SCMs containing zircon (ZrSiO4), glass, and baddeleyite (ZrO2) as the main phases are formed. Zirconium is concentrated mainly in two phases, zircon and baddeleyite. The rate of Zr leaching from the synthesized SCMs into H2O after 28 days is ~1.0 × 10–9g/(cm2day).
