Barium titanate and tin become harder than diamond.(COMPOSITES)

From: Advanced Ceramics Report | Date: April 1, 2007 | Copyright information

Researchers from the University of Wisconsin-Madison, USA, have developed a material that is stiffer than diamond, using a combination of barium titanate and tin.

While diamond achieves its stability via dense, directional, tight atomic bonds, the researchers created their composite material by connecting the barium titanate and tin in a novel way. The material has the ability to change volume during phase transformation, as barium titanate goes from one solid to another solid, said Professor of Engineering Physics, Roderic Lakes.

Barium titanate is commonly used in ...
