| Uses | Strontium dioxide (SrO2) can cause fires or explode when heated and in
contact with organic substances. It is used as both a reducing agent and an oxidizing agent. |
| Chemical Properties | white to off-white powder |
| Chemical Properties | Strontium peroxide is a lightcolored solid of good thermal stability. Commercial strontium peroxide contains about 85% SrO2 and 10% active oxygen. |
| Uses | Strontium peroxide or strontium dioxide (SrO2) can cause fires or explode when heated and in contact with organic substances. It is used as both a reducing agent and an oxidizing agent. |
| Uses | The only substantial application for this compound is in pyrotechnics. Strontium peroxide produces a red color in flames. |
| Uses | Strontium Peroxide is
an oxidizing agent that is used for bleaching. It has
also been used in some pyrotechnic displays to provide a vivid-red color. |
| Preparation | Like the other alkaline earth peroxides, it can be
prepared by reaction of the nitrate and sodium peroxide
in a cold solution:
Sr(NO3)2＋ Na2O2＋xH2O
SrO2·xH2O＋2NaNO3
The hydrated form is usually the octahydrate. If the
anhydrate is desired, the hydrated peroxide is dried
and then sintered at 350°C for 10 min or less:
SrO2·xH2O＋ heat→SrO＋SrO2＋H2O |
| General Description | A white powder. Insoluble in water and slowly decomposed by water. Noncombustible, but accelerates the burning of combustible material. |
| Air & Water Reactions | Insoluble in water and slowly decomposed by water. |
| Reactivity Profile | Strontium peroxide may explode from friction, heat or contamination. Accelerates burning when involved in a fire. May ignite combustibles (wood, paper, oil, clothing, etc.). If the combustible material is finely divided the mixture may be explosive. |
| Health Hazard | TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Fire may produce irritating and/or toxic gases. Toxic fumes or dust may accumulate in confined areas (basement, tanks, hopper/tank cars, etc.). Runoff from fire control or dilution water may cause pollution. |
| Fire Hazard | May explode from friction, heat or contamination. These substances will accelerate burning when involved in a fire. May ignite combustibles (wood, paper, oil, clothing, etc.). Some will react explosively with hydrocarbons (fuels). Containers may explode when heated. Runoff may create fire or explosion hazard. |
| Flammability and Explosibility | Not classified |
| Safety Profile | A powerful oxidizer. A skin, eye, and mucous membrane irritant. Mixtures with organic materials readily ignite with friction or on contact with moisture. See also PEROXIDES and STRONTIUM COMPOUNDS. |
