Potassium nitrate can be used in agriculture, industry, and solar power plants. Each aspect has its unique role. In agriculture, potassium nitrate is used as a chlorine-free water-soluble fertilizer to supplement crops with nitrate nitrogen and potassium. In view of the unique product characteristics and advantages connected to the product characteristics and advantages, its target market is a variety of high value-added crops, such as vegetables, fruits and flowers. In addition, for chlorine-sensitive crops, such as potatoes, strawberries, beans, cabbage, lettuce, peanuts, carrots, onions, blueberries, tobacco, apricots, grapefruits and avocados, the quality depends on the use of chlorine-free K sources, such as potassium nitrate Connect to product features and advantages.

Industrially, it is mainly used to make fertilizers. In addition, potassium nitrate is widely used, including glass production, mining and civil engineering blasting, metal processing, and fireworks manufacturing. It has recently been used as a method to greatly improve the efficiency of concentrated solar power (CSP) plants.

At the same time, potassium nitrate is an essential storage medium for storing thermal energy in CSP plants. Solar energy is a renewable green energy and is increasingly used as an alternative energy source to reduce the global greenhouse effect.

If the nitrate "rechargeable battery" is used to store the heat generated by the sun, its efficiency can even be improved. Use large mirrors or reflectors to reflect sunlight to directly or indirectly heat the molten nitrate mixture composed of sodium potassium nitrate. This mixture can store thermal energy very efficiently for several days due to its potentially high heat capacity. The stored energy can be released at any time, even on a cloudy day without sunlight. This new process enables the CSP plant to continuously generate electricity for a long time every day, improving the power generation efficiency.
