摘　　要：固相法是一种常用的材料制备方法,但是在使用碱金属的碳酸盐为原料时常面临一定程度的热损失。采用Na_(2)CO_(3)作为钠源制备了Ruddlesden-Popper结构的NaGdTiO_(4),通过X射线衍射(XRD)、傅里叶红外光谱(FTIR)和扫描电子显微镜(SEM)等手段,系统研究了不同钠比例对材料性质的影响。结果表明过量15%的Na_(2)CO_(3)所得粉体具有更高的纯度,并保持良好的吸水能力和层状结构,所得材料表现出良好的热稳定性,可以应用于高温等领域。The solid-state method is a commonly used material preparation technique,but it often experiences a certain degree of heat loss when utilizing alkali metal carbonates as raw materials.In this study,Ruddlesden Popper structured NaGdTiO_(4)was synthesized using Na_(2)CO_(3)as the sodium source.The impact of different Na source ratios on material properties was systematically investigated through X-ray diffraction(XRD),fourier transform infrared spectroscopy(FTIR),and scanning electron microscopy(SEM).The findings reveal that the powder obtained with an excess of 15%Na_(2)CO_(3)exhibits higher purity,retains good water absorption ability and layered structure.Furthermore,the resulting material demonstrates excellent thermal stability,making it suitable for applications in high-temperature and other related fields.
