Chinese Manufacturer for Industrial Grade Potassium Nitrate, 99.4% Purity KNO3 for Fireworks and Firecrackers
1. Industrial Grade Potassium Nitrate Introduction
Industrial grade potassium nitrate, also known as saltpeter or nitrate of potash, is a widely used chemical compound with a range of applications in various industries. It is a white crystalline solid that consists of potassium, nitrogen, and oxygen. With its unique properties and characteristics, industrial-grade potassium nitrate finds utility in sectors such as agriculture, fireworks, food preservation, glass manufacturing, black powder and more.
Potassium nitrate is a strong oxidizing agent that can cause combustion and explosion when in contact with organic matter. Therefore, potassium nitrate should be stored in a cool and dry place, away from flames and heat sources. Avoid co storage and transportation with reducing agents, acids, flammable materials, and metal powders.

3. 99.4% Purity KNO3 for Fireworks and Firecrackers
Potassium nitrate (KNO3) is a key ingredient in the production of fireworks and firecrackers. It plays a crucial role in creating the vibrant colors, explosive effects, and controlled combustion of fireworks. Here's how potassium nitrate is used in fireworks:
Oxidizer: Potassium nitrate is a powerful oxidizing agent. When heated or ignited, it releases oxygen, which is essential for the combustion of other components in the fireworks composition. It provides the necessary oxygen to sustain the chemical reactions that produce the desired visual and auditory effects.
Color production: Different metal salts are combined with potassium nitrate to produce the vivid colors seen in fireworks. These metal salts, known as colorants or metal chlorides, are mixed with potassium nitrate and other fuel components. When the firework is ignited, the heat from the combustion excites the metal ions, causing them to emit characteristic colors. For example, strontium salts produce red, barium salts produce green, and copper salts produce blue colors.
Fuel component: Potassium nitrate also acts as a fuel component in certain fireworks compositions. It provides a source of oxygen and helps sustain the combustion reactions. When combined with other fuels, such as sulfur or charcoal, it contributes to the overall energy release and propulsion of the firework.
4. Industrial Grade Potassium Nitrate Application
Potassium nitrate (KNO3) is an important chemical substance that has a wide range of applications in industry.
4.1. Glass industry
Potassium nitrate is used as a raw material in the glass industry. Potassium nitrate can provide oxygen and promote the impurities in the glass to be oxidized and decomposed, thereby improving the transparency and quality of the glass. Potassium nitrate can also control the melting point of glass, adjust the composition and properties of glass, so that it has different uses and characteristics. The application of potassium nitrate in the glass industry has improved the quality of glass products, and is widely used in construction, home, utensils and other fields.
4.2. Metallurgical industry
Potassium nitrate has many applications in the metallurgical industry. First, potassium nitrate can be used to extract the metal silver. Silver nitrate can be produced by mixing silver containing ore with potassium nitrate, and then metallic silver can be obtained by reduction reaction. In addition, potassium nitrate can also be used as a refining agent of tungsten, so that its purity reaches more than 99.95%. At the same time, potassium nitrate can also be used in the production of ammonium phosphate and hardening agent preparation.
4.3. CSP industry
CSP plants are much more powerful than solar photovoltaic plants, and can be even more powerful by using nitrate "rechargeable batteries" to store the heat generated by the sun. CSP plants use large mirrors or reflectors to reflect sunlight to directly or directly heat a molten nitrate mixture composed of sodium nitrate and potassium nitrate. This mixture can store heat energy very efficiently for up to several days due to its potentially high thermal capacity. The stored energy can be released at any time, even on cloudy days when the sun is not shining. The new process allows CSP plants to continuously generate electricity for long periods of time every day, increasing power generation.
