High-Pressure Synthesis and Study of NO⁺NO₃⁻ and NO₂⁺NO₃⁻ Ionic Solids

Figure 8

Phase diagram showing the domain of stability of crystalline NO₂⁺NO₃⁻ on decompression of a mixture of NO₂⁺NO₃⁻ and NO⁺NO₃⁻. A textured area indicates the eventual extension of the region of (meta)stability of NO⁺NO₃⁻ solid to low pressures.
