Potassium perchlorate Chemical Properties,Uses,Production

Chemical Properties

colourless crystals or white powder


In explosives, pyrotechnics and photography, in analytical chemistry.

General Description

A white crystalline solid. Forms explosive mixtures wilh certain combustible materials. Difficult to burn, but will accelerate burning of combustible materials. Prolonged exposure to fire or heat may result in an explosion. Used in explosives, pyrotechnics, photography.

Air & Water Reactions

Slight solubility in water (7.55 mg /mL of cold water).

Reactivity Profile

Potassium perchlorate is a strong oxidizing agent. Explosively decomposes at or over 400°C. Decomposed by organic matter (reducible material) and on concussion [Merck 11th ed. 1989]. Mixture with powdered magnesium is a friction-sensitive explosive [Safety Eng. Reports 1947]. Incompatible with reducing agents, such as: metal powders aluminum, titanium, barium, magnesium, nickel, and various metal hydrides, sulfur.


Fire risk in contact with organic materials, strong oxidizing agent. Strong irritant.

Health Hazard

Inhalation, ingestion or contact (skin, eyes) with vapors or substance may cause severe injury, burns or death. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause pollution.

Fire Hazard

These substances will accelerate burning when involved in a fire. Some may decompose explosively when heated or involved in a fire. May explode from heat or contamination. Some will react explosively with hydrocarbons (fuels). May ignite combustibles (wood, paper, oil, clothing, etc.). Containers may explode when heated. Runoff may create fire or explosion hazard.

Safety Profile

An experimental teratogen. A powerful oxidizer. Severe irritant to skin, eyes, and mucous membranes. Has been implicated in aplastic anemia. Absorption can cause methemoglobinemia and hdney injury. It has been involved in many industrial explosions. Explodes on contact with aluminum + barium nitrate + potassium nitrate + water. Forms explosive mixtures with aluminum powder + titanium dioxide, ethylene glycol (240°C), cotton lint (245°C), furfural (27O°C), lactose, metal powders (e.g., aluminum, iron, magnesium, molybdenum, nickel, tantalum, titanium), sulfur, titanium hydride. Reaction with ethanol + heat forms the explosive ethyl perchlorate. Violent reaction or igmtion under the proper conditions with aluminum + aluminum fluoride, barium chromate + tungsten or titanium, boron + magnesium + silicone rubber, ferrocenium lammine- tetrahs(thiocyanat0-N) chromate(1-), potassium hexacyanocobaltate(3-), Al + Mg, charcoal, F2, Ni + Ti, reducing agents. When heated to decomposition it emits very toxic fumes of K2O and Cl-. See also PERCHLORATES.

Purification Methods

It crystallises from boiling water (5mL/g) on cooling. Dry it under vacuum at 105o.
