Barium titanate, BaTiO3 is a ceramic used in MLCC:s between the metal plates.
In a procedure to determine Ba and Ti content in a sample, 0.5g of barium titanate was dissolved by heating it in 15 ml of concentrated HCl.
- Melting point : 1625-1654° C
- Density : 5.95 - 6.08 g/cm3
Barium titanate is mostly inert, but a dust mask should be used whenever dust is produced, for example when crushing MLCC:s. Some MSDS holds barium titanate as toxic for digestion at LD50= 12g/kg, but that's a massive amount and not likely to happen.
