Phosphate-based glass-ceramics were prepared by a traditional glass melt-quenching method in a high-temperature furnace. The effects of the ZrO₂ substituted for Na₂O on the crystal phase, thermal behavior, structure, and chemical stability of the prepared glass-ceramics were investigated in detail. X-ray diffraction (XRD) analysis showed that NaZr₂(PO₄)₃ is the main crystalline phase of all the studied samples. ZrP₂O₇ and FePO₄ respectively appeared when the ZrO₂ substituted for Na₂O reached or exceeded 8 mol% and 12 mol%. FTIR and Raman spectra showed that the network structure of the studied glass-ceramics consisted mainly of orthophosphate units, pyrophosphate units, and a small amount of metaphosphate units and [BO₄] units. For the samples containing 10 mol% ZrO₂ or less, the normalized leaching rates of Zr (LR_Zr), Fe (LR_Fe), Na (LR_Na), and P (LR_P) remained low (2.5 × 10⁻⁶ g m⁻² d⁻¹, 3.3 × 10⁻⁶ g m⁻² d⁻¹, 2.5 × 10⁻³ g m⁻² d⁻¹, and 6.2 × 10⁻⁴ g m⁻² d⁻¹, respectively) after immersion in deionized water at 90 °C for 28 days. The obtained results suggest that the traditional glass making process may potentially be applicable to the synthesis of some phosphate-based glass-ceramics for immobilizing nuclear waste.

磷酸盐基玻璃陶瓷是通过传统的玻璃熔体淬火方法在高温炉中制备的。详细研究了用ZrO ₂代替Na ₂ O对制备的微晶玻璃的晶相，热行为，结构和化学稳定性的影响。X射线衍射（XRD）分析表明，NaZr ₂（PO ₄）₃是所有研究样品的主要结晶相。ZrO ₂代替Na ₂时分别出现ZrP ₂ O ₇和FePO _4。O达到或超过8摩尔％和12摩尔％。FTIR和拉曼光谱表明，所研究的玻璃陶瓷的网络结构主要由正磷酸盐单元，焦磷酸盐单元，少量的偏磷酸盐单元和[BO ₄ ]单元组成。对于ZrO ₂等于或小于10 mol％的样品，Zr（LR _Zr），Fe（LR _Fe），Na（LR _Na）和P（LR _P）的归一化浸出率仍然很低（2.5×10 ^-6  g m ^-2  d ^-1，3.3×10 ^-6 克米^-2  d ^-1，2.5×10 ^-3 克间在90°C的去离子水中浸泡28天后，分别为^-2  d ^-1和6.2×10 ^-4  g m ^-2  d ^-1。获得的结果表明，传统的玻璃制造工艺可能潜在地适用于某些磷酸化的玻璃陶瓷的合成，以固定核废料。
