Industrial-grade potassium nitrate powder for fireworks is a high-performance, safe and reliable oxidant

99.5% industrial-grade potassium nitrate powder for fireworks is a high-purity oxidant, specially designed for the fireworks and firecrackers industry. Its excellent stability and controllable reaction characteristics have made it the core raw material for manufacturing black powder, fuse wires and various fireworks products, ensuring a safe and brilliant display effect. Whether it’s traditional firecrackers or large fireworks, this product can provide balanced combustion support and is the preferred material for fireworks manufacturers.

Why choose our potassium nitrate specifically for fireworks?

Potassium nitrate (KNO₃) is mainly used as an oxidizing agent in fireworks, and its purity directly affects the combustion efficiency and safety.

• High purity guarantee: 99.5% potassium nitrate main content (meeting the industrial first-class product standard), ensuring strong consistency in chemical reactions and avoiding abnormal ignition caused by impurities.
• Powder form advantages: Fine powder particles increase the contact area, mix more evenly with fuels (such as sulfur, charcoal), and enhance the stability of combustion rate.
• Industry-specific: Strictly control key indicators such as chloride ions and hygroscopicity to prevent moisture and caking, and extend the storage life of fireworks.

FAQ

Q1: What is the significance of 99.4% purity for fireworks production?

A: High purity reduces impurity interference, ensures stable burning speed, and lowers the risk of flame failure or explosion.

Q2: What are the differences between powdered and granular potassium nitrate in fireworks?

A: The powder is mixed more evenly and is suitable for fine fireworks. Pellets are mostly used in traditional firecrackers.

Q3: How to prevent potassium nitrate from getting damp?

A: Use moisture-proof packaging, and control the humidity in the warehouse
