Solids with an [NZP] skeleton in their structure from a very broad family presenting very different properties with varying chemical composition. These properties range from radioactive nuclide immobilization and insulation to ionic and/or electronic conduction, extending to the field of very low thermal expansion among others. The open [NZP] skeleton provides the stability and flexibility necessary to form continuous ranges of solid solution, allowing the tailoring of the best composition-property-structure material. Chemical activity may become particularly high at the surface and absorption reactions and catalytic properties have the highest interest at present. In this paper, chemistry and properties of [NZP] solids are presented as the result of the interactions between the [NZP] skeleton and the counter-ions. Properties of ion transport, anisotropic thermal expansion, ion exchange, isomorphism, polymorphism, phase transitions, exchange and reactivity at low temperatures are discussed.
