Description

Sodium Nitrate: Sodium nitrate is alkali metal nitrate salt with the formula NaNO3. This metal nitrate salt readily available form is nitrate anion (NO3?). Sodium nitrate is produced industrially by neutralizing the nitric acid with sodium bicarbonate or sodium carbonate. As a food preservative, sodium nitrate is used in meats and poultry, an oxidizer in fireworks, gold refineries, and solar power plants.

Sodium nitrate is used together with potassium nitrate and calcium nitrate for heat storage and, more recently, for heat transfer in solar power plants
