摘要

摘要研究了通过将熔融玄武岩与 ZrO2 在 1623 K 下于空气中作用 5 小时而制成的铸石基质（CSM）中的相形成。在上述条件下熔化的玄武岩主要含有两种尖晶石（残余和新形成的）、成分为 Mg0.66Ca0.60Fe0.26Ti0.05Al0.66Si1.80O6 的挛辉石和玻璃。当玄武岩与 ZrO2（重量比为 1:1）熔融时，会形成以锆石（ZrSiO4）、玻璃和巴德来石（ZrO2）为主要相的 CSM。锆主要富集在锆石和巴德莱石这两相中。28 天后，锆从合成的 CSMs 浸出到 H2O 中的速率约为 1.0 × 10-9 g/（cm2 天）。

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

Abstract

Phase formation in cast stone matrices (CSMs) fabricated through the interaction of comelted basalt with ZrO₂ 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_0.66Ca_0.60Fe₀.₂₆Ti_0.05Al_0.66Si_1.80O₆, and glass as the major phases. When basalt is comelted with ZrO₂, taken in a weight ratio of 1 : 1, CSMs containing zircon (ZrSiO₄), glass, and baddeleyite (ZrO₂) 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 H₂O after 28 days is ~1.0 × 10^–9 g/(cm² day).
