ZrO2粉体在不同阶段的红外光谱,样1为未经处理的样品,样2为在酸处理前进行AHP处理的样品,样3为在酸处理后进行AHP处理的样品。所有样品制备的前提是碱式碳酸锆在110 ℃,pH=13的碱性条件下进行水热反应。所谓AHP处理即,在水热后的产品在碱性过氧化氢的中50 ℃剧烈搅拌5小时。
FTIR spectra of ZrO2 powders at different stages:(1) untreated ZrO2, (2) AHP-treated ZrO2 before acid treatment, and (3) AHP-treated ZrO2 after acid treatment. All samples were prepared by hydrothermal reaction of basic zirconium carbonate at 110 ℃, pH=13. The so-called AHP treatment means that the product is stirred vigorously at 50 ℃ of alkaline hydrogen peroxide for 5 hours after hydrothermal treatment.
