概要
Barium zirconium oxide is an oxide of barium and zirconium. 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.

化学的性質
化学的特性Barium zirconate (BaZrO₃) is a light gray-buff powder. It is insoluble in water and alkalis, and slightly soluble in acids. It is used in the manufacture of white, easily colored silicone rubber compounds that exhibit good heat stability at temperatures up to 500 °F (approximately 260 °C), as well as in electronics applications.

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)

薬理情報
Metabolism/Metabolites
Barium compounds are absorbed via ingestion and inhalation, the extent of which depends on the individual compound. In the body, the majority of the barium is found in the bone, while small amounts exists in the muscle, adipose, skin, and connective tissue. Barium is not metabolized in the body, but it may be transported or incorporated into complexes or tissues. Barium is excreted in the urine and faeces. (L214)
