Orthonitrate is a tetrahedral oxoanion of nitrogen with the formula NO3−4. It was first identified in 1977 and is currently known in only two compounds, sodium orthonitrate (Na3NO4) and potassium orthonitrate (K3NO4). The corresponding oxoacid, orthonitric acid (H3NO4), is hypothetical and has never been observed. Sodium and potassium orthonitrate can be prepared by fusion of the nitrate and metal oxide under high temperatures and ideally high pressures (several GPa).NaNO3 + Na2O → Na3NO4 (300 °C for 3 days)
