Overview
About Potassium Nitrate
Potassium nitrate is a crystalline salt and a strong oxidiser. It is a white solid, sometimes white to dirty grey, and dissolves readily in hot water.
It is used as a fertiliser, in food preservation, in medicines and toothpaste, as the electrolyte in salt bridges, and as a thermal storage medium in power generation.
We supply potassium nitrate to pharmaceutical companies, research laboratories and other industries.
