Barium hexaferrite
Barium ferrite is a chemical compound of barium and iron. It is used as a component in magnetic stripe cards. Barium is a metallic alkaline earth metal with the symbol Ba, and atomic number 56. It never occurs in nature in its pure form due to its reactivity with air, but combines with other chemicals such as sulfur or carbon and oxygen to form barium compounds that may be found as minerals.

- Health Effects: The health effects of the different barium compounds depend on how well the compound dissolves in water or the stomach contents. At low doses, barium acts as a muscle stimulant, while higher doses affect the nervous system, causing cardiac irregularities, tremors, weakness, anxiety, dyspnea, paralysisand possibly death. Barium may also cause gastrointestinal disturbances, damage the kidneys and cause decreases in body weight. (L214) Source: Toxin and Toxin Target Database (T3DB)
- Toxicity Summary: Barium is a competitive potassium channel antagonist that blocks the passive efflux of intracellular potassium, resulting in a shift of potassium from extracellular to intracellular compartments. The intracellular translocation of potassium results in a decreased resting membrane potential, making the muscle fibers electrically unexcitable and causing paralysis. Some of these barium's effects may also be due to barium induced neuromuscular blockade and membrane depolarization. (L214) Source: Toxin and Toxin Target Database (T3DB)
- Uses: Barium ferrite is used as a component in magnetic stripe cards. (L244) Source: Toxin and Toxin Target Database (T3DB)
