PROCESS FOR THE PREPARATION A POWDER OF SODIUM ZIRCONIUMPHOSPHATE STRUCTURE FOR A REDUCED HEAT EXPANSIVE MATERIALS

摘要

The sodium zirconium phosphate powder has excellent properties for a low-temperature expansion and heat-resistant shock material. The method includes mixing urea and ammonium nitrate with a material mixture of metal nitrate, zirconyl nitrate and ammonium dihydrogen phosphate to produce slurry, followed by naturally igniting the slurry at a temperature of 500 degrees centigrade.
