What is the phase diagram of nitrogen? The nitrogen phase diagram shows the phase behavior ... T-P Phase Diagram of Nitrogen at High Pressures ... This was the most appropriate functional form to describe the experimental T-P phase diagram of nitrogen since T varies nonlinearly with P for the low-pressure phase β and higher-pressure phases δ, ε, ξ and η (Fig. 1). For the high-pressure experiments by keeping the temperature constant (for example, at room temperature), the pressure is increased, which also applies to the solid nitrogen as studied here.
