The Research Of Preparing The Phosphate Ceramics Ca_1-XBa_XZr₄P₆O₂₄ With Low Thermal Expansion Properties

The [NZP] family of materials has attracted worldwide attention for its low and tailorable thermal expansion coefficient and other useful properties. They now have emerged as potential candidates in many applications, including catalyst supports, automobile engine components, heat exchangers, and coating materials for space technology.It is possible to develop the suitable compositions in the [NZP] family with the near-zero bulk thermal expansion and the minimal thermal expansion anisotropy of crystal, thereby minimizing the production of microcracks during cooling. For these purposes, a new type of [NZP] materials-Ca1-xBaxZr4P6O24(0
