We have studied a relatively overlooked subset of the MnO-doped zinc borosilicate glass system with a goal of investigating the effects of MnO-doping on the thermal stability of crystalline phase formation in the system. A glass system of general composition 55ZnO–20B 2 O 3 –25SiO 2 with added MnO dopant, which replaces Zn modifier locations with Mn, ratios of 0, 0.005, 0.01, and 0.015 MnO:ZnO were prepared, via batch melting at 1550 °C for 1.5 h. The glasses were characterized using differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive spectrometry (EDS). Thermal analysis, followed by detailed XRD and Rietveld structural refinement, revealed the formation of zinc borate (Zn 4 O(BO 2 ) 6 ), willemite (Zn 2 SiO 4 ), and manganese zinc silicate ((ZnMn)SiO 4 ) crystallites after heat-treatment at 875 °C for 4 h and zinc borate crystallites influenced by the borate anomaly in samples heated to ≈ 955 °C at a ramp rate of 10 °C/min and held for 4 h. Microstructure and elemental maps confirmed that the zinc borate had become an integral part of both glass and crystalline phases in the resulting glass–ceramic samples. MnO-content influenced the formation of the boron-containing glass phase via the borate anomaly.

MnO掺杂的硼硅酸锌玻璃中晶相的热稳定性

我们研究了 MnO 掺杂的硼硅酸锌玻璃系统的一个相对被忽视的子集，目的是研究 MnO 掺杂对系统中结晶相形成的热稳定性的影响。玻璃体系的一般成分为 55ZnO–20B 2 O 3 –25SiO 2 并添加了 MnO 掺杂剂，用 Mn 代替了 Zn 改性剂位置，通过在 1550 ° 分批熔化制备了 0、0.005、0.01 和 0.015 MnO:ZnO 的比例C 1.5 小时。使用差示扫描量热法 (DSC)、热重分析 (TGA)、X 射线衍射 (XRD)、扫描电子显微镜 (SEM)、能量色散光谱法 (EDS) 对玻璃进行表征。热分析，然后是详细的 XRD 和 Rietveld 结构精修，揭示了硼酸锌 (Zn 4 O(BO 2 ) 6 )、硅锌矿 (Zn 2 SiO 4 )、和锰酸锌 ((ZnMn)SiO 4 ) 微晶在 875 °C 下热处理 4 小时后，硼酸锌微晶受硼酸异常影响的样品以 10 °C/min 的升温速率加热至 ≈ 955 °C并保持 4 h。微观结构和元素图证实，硼酸锌已成为所得玻璃陶瓷样品中玻璃相和结晶相的组成部分。MnO 含量通过硼酸盐异常影响含硼玻璃相的形成。微观结构和元素图证实，硼酸锌已成为所得玻璃陶瓷样品中玻璃相和结晶相的组成部分。MnO 含量通过硼酸盐异常影响含硼玻璃相的形成。微观结构和元素图证实，硼酸锌已成为所得玻璃陶瓷样品中玻璃相和结晶相的组成部分。MnO 含量通过硼酸盐异常影响含硼玻璃相的形成。
