Potassium Nitrate (KNO3) is a product used in a wide variety of applications. These include fertilisers, cosmetics, personal care products, anti-freeze products and washing & cleaning products. It comes as a white to dirty grey crystalline solid powder with a high solubility in water.

Potassium Nitrate is an oxidator and needs to be separated from strong reductors like metal powders (aluminium, magnesium, and iron), and organic compounds, such as charcoal, carbohydrates and sugars (glucose, sucrose and dextrin).

We sell potassium nitrate of technical quality with a purity higher than 99%. This is white/slightly yellowish crystal powder, free of chlorine, sodium and heavy metals. It is delivered in strong plastic sealed container buckets which allow safe transport and storage.

This product falls under the law for regulated precursors and we are therefore obliged to ask you to fill in what you plan on using this product for.
