【Abstract】 The crystal chemistry,composition,powder preparation and theramal properties of NZP family ceramics were reviewed,and existing problems and developing trend of NZP family ceramics were discussed.Based on the zero expansion character of NZP,two new compounds were designed-SrSn 4(PO 4) 6 and CaSn 4(PO 4) 6.They were synthesized by hydrothermal and coprecipitaion methods,and CSP & SSP were analysed through grain size,XRD,IR,SEN,thermal expansion and mechanical strength.更多还原
