Product Description

• 1. Matches and Ignition Devices

  Red phosphorus is a crucial component in the production of safety matches. It is used on the striking surface of matchboxes, where it reacts with potassium chlorate in the match head to produce a spark when rubbed. This innovation significantly improved the safety of matches by separating the reactive components until the moment of ignition.

  2. Flame Retardants

  Red phosphorus is widely used as a flame retardant in various materials, including plastics and textiles. It works by forming a protective char layer and polyphosphoric acid when exposed to heat, which inhibits flame propagation. However, its use in electronic systems has been restricted due to issues like elevated leakage current in semiconductor devices.

  3. Smoke and Flare Devices

  Red phosphorus is used in military and emergency signaling devices. When mixed with magnesium and a binder, it can create a dense smoke screen, which is useful for concealment and signaling. It is also used in flares to aid in the ignition and sustained combustion process.

  4. Chemical Synthesis

  Red phosphorus is used in the synthesis of various chemicals, including phosphorus tribromide and phosphorus triiodide, which are important halogenation agents. These compounds are used in organic chemistry to replace hydroxyl groups in alcohols and to produce hydroiodic acid.

  5. Metallurgy

  Red phosphorus is used in the production of ferrophosphorus, an alloying agent in high-strength low-alloy steel. It is also used in the smelting of copper to remove oxygen impurities, resulting in phosphorus-containing copper alloys with improved properties.

  6. Photocatalysis and Energy Applications

  Red phosphorus has been explored as an elemental photocatalyst for hydrogen production from water. It is also being researched for use as an anode material in sodium-ion batteries.

  7. Other Uses

• Pesticides: Red phosphorus is occasionally used in the production of certain pesticides.
• Illicit Drug Production: It is sometimes used in the illicit production of methamphetamine due to its ability to generate hydrogen iodide. This has led to regulatory controls on its handling and distribution.
