The article focuses on the structural characteristics, stability, and properties of Aurivillius phases Bin 1Fen-3Ti3O3n 3, a perovskite-like block chemical compound. It says that based on the synthesize of the block, the changes in its structure reflects the distribution of titanium and iron ions within the layers of the block. It mentions that if the thickness of the block increases, it results to the decline of its stability.
