摘　　要：采用不同工艺分别制备了锡酸钙样品,分别对样品的物相结构、微观形貌、产品纯度及粒径分布进行测试。其中,XRD测试结果显示,两个工艺合成的锡酸钙均无杂质峰生成,且工艺A制备的样品结晶性较好;扫描电镜(SEM)测试结果表明,工艺A制备的样品较为分散、分布较为均匀、颗粒尺寸较小(200~700 nm);粒度和纯度测试结果显示,工艺A比工艺B制备锡酸钙产品具有较小的颗粒度,且煅烧6 h后,纯品纯度较高,为99.41%。这表明在该工艺条件下,通过SnCl_(4)·5H_(2)O为原料制备钙钛矿型锡酸钙样品具有较好的晶体结构和微观形貌,产品指标较好,有望表现出较好的阻燃性能。In this paper,calcium stannate samples were prepared by different processes,and the phase structure,microscopic morphology,product purity and particle size distribution of the samples were tested.First,the XRD test results showed that there was no impurity peaks generation in the calcium stannate synthesized by the two processes,and the samples prepared in process A had good crystallinity;Second,The results of scanning electron microscopy(SEM)showed that the samples prepared by process A were more dispersed,more evenly distributed,and the particle size was smaller(200-700 nm);the results of particle size and purity test showed that the calcium stannate product prepared by process A has smaller particle size than that prepared by process B,and the purity of the pure product was 99.41%after calcination for 6 h,This indicated that the perovskite calcium stannate sample prepared by SnCl_(4)·5H_(2)O had better crystal structure and microstructure under this process.The product index is good,is expected to show a better flame retardant performance.
