以SrCO_3、SiO_2、ZrO_2和(NH_4)H_2PO_4为实验原料,采用固相反应法制备出磷酸盐Sr_(1+x)Zr_4P_(6-2x)Si_(2x)O_(24)(x=0～0.4)粉体.XRD和SEM分析表明:在1100 ℃,4 h温度下煅烧能够合成单相Sr_(1+x)Zr_4P_(6-2x)Si_(2x)O_(24)(x=0～0.4)粉体,1100 ℃,4 h条件下制备的Sr_(1+x)Zr_4P_(6-2x)Si_(2x)O_(24)(x=0～0.4)粉体成球状,平均粒径在300～500 nm之间.在1100 ℃煅烧温度下适当延长保温时间,有利于Sr_(1+x)Zr_4P_(6-2x)Si_(2x)O_(24)(x=0～0.4)单相粉体的形成.
Sr_(1+x)Zr_4P_(6-2x)Si_(2x)O_(24)(x=0～0.4) powders were synthesized using SrCO_3, SiO_2, ZrO_2 and (NH_4)H_2PO_4 as raw materials by solid state reaction method. The phase and microstructure were investigated by XRD and SEM. Results showed that pure Sr_(1+x)Zr_4P_(6-2x)Si_(2x)O_(24) (x=0～0.4) powders were obtained at 1100 ℃ for 4 h, the prepared SZP powders were granular, and the average grain size was about 300～500 nm. Increasing the calcined time appropriately at 1100 ℃ calcinations temperature was beneficial to the formation of Sr_(1+x)Zr_4P_(6-2x)Si_(2x)O_(24)(x=0～0.4) single-phase powders.
