Barium Stannate

Barium stannate is a chemical compound with the molecular formula BaSnO3. It is a white crystalline powder that is insoluble in water but soluble in acids. Barium stannate has a perovskite crystal structure, which means that it has a cubic unit cell with the barium ions located at the corners and the tin and oxygen ions arranged in a regular pattern in the center.

Barium stannate is used as a dielectric material in ceramic capacitors and multilayer ceramic capacitors (MLCCs) due to its high dielectric constant and low loss tangent. It is also used as a substrate material for thin-film electronic devices and as a component in high-temperature piezoelectric transducers.

In terms of its properties, barium stannate has a melting point of 1,550 °C and a density of 6.10 g/cm3. It is a stable compound and does not decompose at temperatures below its melting point. Barium stannate is non-toxic and has no significant environmental impact.

Overall, barium stannate is an important material in the electronics industry due to its excellent dielectric properties and stability under high temperatures.
