Potassium nitrate, with the chemical formula KNO₃, is an inorganic compound also known as saltpeter. It appears as colorless transparent crystals or white powder, highly soluble in water.
As a key fertilizer raw material, it provides essential potassium and nitrogen nutrients for plants, widely used in agriculture to boost crop yields.
In industry, it serves as an important explosives component in fireworks, gunpowder, and mining explosives due to its oxidizing properties.
It also finds applications in food preservation, medicine, and laboratory reagents. With growing global demand for sustainable agriculture and industrial safety, potassium nitrate's production technology and supply chain stability remain hot topics, driving innovations in efficient extraction and eco-friendly manufacturing processes.
