Is barium titanate hazardous?
Insoluble barium compounds (barium titanate) have low toxicity. However, soluble barium compounds can lead to toxic effects. Soluble barium salts, such as the chloride and sulfide, are poisonous when taken by mouth.

Is barium titanate pyroelectric?
The pyroelectric coefficient (at constant stress) of a 95 wt% BaTiO3, 5 wt% CaTiO3 ceramic composition (Clevite Ceramic B) was measured over the temperature range from 4.9° to 400°K. The pyroelectric coefficient showed no anomalous behavior below 150°K.
Is barium titanate a piezoelectric material?
Barium titanate, BaTiO3, has been the first commercial ferroelectric and piezoelectric material. After more than 70 years from its discovery, it is still the most widely used functional ceramic in the electronic industry, mainly as a dielectric in multilayer ceramic capacitors.
Is barium titanate a semiconductor?
A perovskite like barium titanate (BaTiO3) is a common ferroelectric non stoichiometric substance possessing a high dielectric constant. So BaTiO3 may act both n- type and p-type semiconductor.
What is the Curie temperature of barium titanate?
120 °C
Barium titanate (BaTiO3), which is a ferroelectric with a Curie temperature of 120 °C, is known to become electrically conductive when polycrystalline samples are doped with rare-earth ions.
Is barium titanate magnetic?
The BaTiO3 prepared exhibited weak ferromagnetism rather than diamagnetism, probably due to the oxygen vacancies at the surface. Paramagnetism was observed for all BaTi1-xCoxO3 samples with 0.05≤x≤0.25. Therefore, the ferromagnetic properties are predominant when the Fe doping level are at a certain range.
Is barium titanate a piezoelectric?
Barium titanate is a white powder and transparent as larger crystals (Veith et al., 2000). This titanate is a ferroelectric ceramic material, with photorefractive effect and piezoelectric properties. It is used in capacitors, electromechanical transducers and nonlinear optics (Xu, 2013).
Who discovered barium titanate?
3.1. Barium titanate (BaTiO3 or BT) ceramics were discovered independently during World War II in three countries: in the US by Wainer and Salomon8 in 1942, in Japan by Ogawa9 in 1944, and in Russia by Vul10 in 1944.
