China High Purity Potassium Nitrate,Vojin New Materials Manufacturers, Suppliers
High purity potassium nitrate is mainly used for manufacturing core raw materials for chemically toughened glass such as 3D windows protective screen glass,sapphire glass screen,smart phone touch function glass panel,car mounted display screen,mobile phone screen cover plate,watch display screen glass cover plate,etc.
High purity potassium nitrate is an inorganic compound, colourless crystal at room temperature, soluble in water. It has the form of colourless transparent rhombohedral crystals or powder or granules. When heated to about 400°C, it will decompose to release oxygen and turn into potassium nitrite, and continue to be heated to decompose into potassium oxide and nitrogen oxide.
High-purity potassium nitrate has many industrial applications. It is an important raw material for the manufacture of black powder, mining powder, fuse, firecrackers, etc. It is also used in fireworks to produce purple sparks. In addition, in the ceramic industry, it is used in the manufacture of porcelain enamel colour medicine; in the glass industry, it is used as glass clarifier, also used in the manufacture of automobile lamp glass shell, optical glass tube glass shell and so on. In the pharmaceutical industry, high purity potassium nitrate is used in the production of penicillin. At the same time, high-purity potassium nitrate is also widely used in agriculture, mainly as a fertiliser, especially for vegetables, fruits, flowers and some chlorine-sensitive crops (e.g. potatoes, strawberries, beans, etc.). As a chlorine-free nitrogen and potassium compound fertiliser, its active ingredients nitrogen and potassium are rapidly absorbed by crops and leave no chemical residues.
Storage Warning: It should be stored in a cool and dry place, away from fire and heat sources, and avoid co-storage and mixing with reducing agents, acids, flammable substances and metal powders. Because of its strong oxidising property, contact with organic matter may cause combustion and explosion.

Frequently Asked Questions
What is the physical form of high purity potassium nitrate?
At room temperature, it is a colourless crystal that is soluble in water. It comes in the form of colourless transparent rhombohedral crystals, powder, or granules.
What happens to high purity potassium nitrate when heated?
When heated to approximately 400°C, it decomposes to release oxygen and turns into potassium nitrite. Continued heating decomposes it further into potassium oxide and nitrogen oxide.
What are the major industrial uses of this compound?
It is a key raw material for manufacturing black powder, mining powder, fuses, and firecrackers. It is also used in fireworks for purple sparks, as glass clarifiers and glass shells in the glass industry, for porcelain enamel colour medicine in ceramics, and in penicillin production within the pharmaceutical industry.
How is high purity potassium nitrate beneficial to agriculture?
It serves as a chlorine-free nitrogen and potassium compound fertiliser. Its active ingredients (nitrogen and potassium) are rapidly absorbed by crops, leaving no chemical residues. It is particularly suitable for vegetables, fruits, flowers, and chlorine-sensitive crops like potatoes, strawberries, and beans.
What are the specific storage requirements and hazards?
It must be stored in a cool, dry place away from heat and fire sources. Do not store or mix it with reducing agents, acids, flammable substances, and metal powders. Due to its strong oxidising properties, contact with organic matter may trigger combustion and explosion.
What packaging options are available?
It is available in plastic woven bags or paper-plastic composite bags lined with a inner plastic bag, with standard net weights of 25kg, 50kg, or in Jumbo bags.
