Cast Stone Matrix Based on Comelts of Basalt and Metal Oxides. Part II. Basalt–ZrO2 System

Phase formation in cast stone matrices (CSMs) fabricated through the interaction of comelted basalt with ZrO 2 at 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 Mg 0.66 Ca 0.60 Fe 0 . 26 Ti...

Description
Summary:Phase formation in cast stone matrices (CSMs) fabricated through the interaction of comelted basalt with ZrO 2 at 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 Mg 0.66 Ca 0.60 Fe 0 . 26 Ti 0.05 Al 0.66 Si 1.80 O 6 , and glass as the major phases. When basalt is comelted with ZrO 2 , taken in a weight ratio of 1 : 1, CSMs containing zircon (ZrSiO 4 ), glass, and baddeleyite (ZrO 2 ) as the major phases are formed. Zirconium is concentrated mainly in two phases, zircon and baddeleyite. The rate of Zr leaching from the synthesized CSMs into H 2 O after 28 days is ~1.0 × 10 –9 g/(cm 2 day).
