Thermophysical properties of NZP-ceramics

Data on the thermophysical properties of NZP ceramics with the structure of the NaZr ₂ (PO ₄ ) ₃ type are generalized. A system of regularities of thermal expansion is proposed, which makes it possible to purposefully predict NZP materials with controlled, including ultra-low, thermal expansion at close to zero anisotropy. The thermodynamic functions of reactions for the synthesis of NZP-phosphates are calculated and the applicability of ceramic technology for their production is substantiated. It is proposed to use NZP-ceramics as heat-insulating materials capable of operating under conditions of sharp temperature changes. Tab. 4, ill. 4, bibliography: 25 titles.
