Chemische Eigenschaften
Strontium peroxide is a lightcolored solid of good thermal stability. Commercial strontium peroxide contains about 85% SrO2 and 10% active oxygen.
Verwenden
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.
synthetische
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
Allgemeine Beschreibung
A white powder. Insoluble in water and slowly decomposed by water. Noncombustible, but accelerates the burning of combustible material.
Air & Water Reaktionen
Insoluble in water and slowly decomposed by water.
Reaktivit?t anzeigen
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.
Brandgefahr
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.
Sicherheitsprofil
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.
