SINGLE CRYSTAL OF BARIUM TITANATE
Advanced Ceramics Report ; Large single crystals of barium titanate for optical use have been sucessfully made by Fujikura Ltd, based in Tokyo, Japan, the company claims. The crystals can be made reproducibly as cubes measuring 20 mm on a side and are optically transparent. The crystal structure is hexagonal and the crystals
Barium titanate and tin become harder than diamond.(COMPOSITES)
Advanced Ceramics Report ; 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

Chemistry and Industry ; Scientists in the US have developed a new composite material that is stiffer than diamond. Barium titanate, which is stiffer than aluminum, was combined within a matrix of relatively soft tin (one quarter as stiff as steel and 20 times stiffer than hard plastic). The tin was melted and the grains
DEPOSITION OF OPTICAL THIN FILMS OF BARIUM TITANATE
Advanced Ceramics Report ; The first epitaxial growth of thin films of barium titanate (BaTiO(3)) using metal organic chemical vapour deposition (MOCVD) has been achieved, a US company claims.
