| Hazard Information | Back Directory | [Chemical Properties]
Strontium chromate a light yellow crystalline solid or powder. | [Chemical Properties]
Yellow powder | [Uses]
Corrosion inhibitor in pigments; in electrochemical processes to control sulfate concentration of solutions. | [General Description]
STRONTIUM CHROMATE(7789-06-2) is a light yellow powder or granular solid. STRONTIUM CHROMATE(7789-06-2) is insoluble in water. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. STRONTIUM CHROMATE(7789-06-2) is used as a pigment, a protective coating against corrosion, and in pyrotechnics. | [Hazard]
Toxic by ingestion. Confirmed carcinogen. | [Reactivity Profile]
Oxidizing agents, such as STRONTIUM CHROMATE, can react with reducing agents to generate heat and products that may be gaseous (causing pressurization of closed containers). The products may themselves be capable of further reactions (such as combustion in the air). The chemical reduction of materials in this group can be rapid or even explosive, but often requires initiation (heat, spark, catalyst, addition of a solvent). Explosive mixtures of inorganic oxidizing agents with reducing agents often persist unchanged for long periods if initiation is prevented. Such systems are typically mixtures of solids, but may involve any combination of physical states. Some inorganic oxidizing agents are salts of metals that are soluble in water; dissolution dilutes but does not nullify the oxidizing power of such materials. Organic compounds, in general, have some reducing power and can in principle react with compounds in this class. Actual reactivity varies greatly with the identity of the organic compound. Inorganic oxidizing agents can react violently with active metals, cyanides, esters, and thiocyanates. Avoid contact with water, acids, and bases. | [Air & Water Reactions]
STRONTIUM CHROMATE is insoluble in water. Reactivity in Water: Produces hazardous solution. | [Health Hazard]
INHALATION: Irritating to mucous membranes. SKIN: Repeated skin contact can cause eczematous dermatitis, with edema and ulceration. INGESTION: Dizziness, intense thirst, abdominal pain, vomiting, shock and oliguria or anuria. | [Potential Exposure]
Strontium chromate is used as a metal protective coating to prevent corrosion, in wash primers; and aluminum flake coatings; colorant in polyvinyl chloride resins and pyrotechnics. | [Fire Hazard]
Behavior in Fire: Heat stable | [First aid]
If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and demulcents and induce vomiting. Do not make an unconscious person vomit | [Shipping]
