Überblick
Barium titanate is a chemical compound of barium and titanium. It is used as a dielectric material for ceramic capacitors and as a piezoelectric material for microphones and other transducers. It can also be found in thermistors and self-regulating electric heating systems, nonlinear optics, and thermal cameras. 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. (L214, 408, L212)

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)
