Sodium Nitrate Formular:NaNO3
White or a little buff fine crystal. The relative molecular weight is 69.0 and density is 2.168. It’s no smell and a little saline taste.Easy to be deliquescence and to dissolve in water. The melting point is 271℃ and decomposition temperature is 320℃. It has the strong oxidizing property, as well as reducing property. It can slowly oxidize into sodium nitrite in the air. Therefore it will become diamino compound composed with ammonia under low temperature.

Sodium nitrate is also a food additive . People also consider it as a preservative and color fixative in cured meats and poultry;
Sodium nitrate is used together with potassium nitrate and calcium nitrate for heat storage .More recently, we use it for heat transfer in solar power plants. A mixture of sodium nitrate, calcium nitrate and potassium nitrate ,is used as energy-storage material in prototype plants。
It is also used in the wastewater industry .Sometimes used by marine aquarists who utilize carbon-dosing techniques. It is used to increase nitrate levels in the water,In order to promote bacterial growth.
1.Stored in the dry and ventilation place . Prevent rain and sunlight exposure,rained,heated .
2. Avoid mixing with organic compound or sulphur or reducer, during storage and transportation in case of explosion.
3.Handle with care against friction and bounce while handling and pile.
4.The fire caused by sodium nitrate can be put out by using lots of water.
15-20 days depend on quantity after receive L/C , prepayment,or others.
