Barium titanate, phase transformations

In the next few paragraphs, we will discuss the processes involved in synthesis ofbarium titanate. This is an extremely important material for electronic industry due to its outstanding ferroelectric, piezoelectric and dielectric properties. Chemistry ofBa and Ti and crystal structure of BaTiOg are relatively simple. Phase transformations of barium titanate have been deeply studied and well documented. Thus, it may be considered as a convenient model oxide material. It is not surprising that a lot of information about application of Pechini method is available for this compound. Here we will attempt to create the complete scenario of barium titanate synthesis by PC method, and then we will expand this knowledge to discuss synthesis of other important multicomponent oxide materials.
