Crystal structures of metal aluminium borates
WebJul 15, 2008 · A new aluminum borate chloride (PKU-8) was synthesized in a flux of boric acid, and the structure was established using powder X-ray diffraction techniques. PKU-8 contains an unusual framework structure of a large cage consisting of 12-membered borate rings [B12O30] and aluminate octahedra clusters [Al7O24]. WebMetal aluminum borates represent a fascinating class of materials. Depending on the composition, they can be useful as catalytic, laser, or nonlinear optical materials. In the early stages of research and development, it can often be difficult to grow the single crystals “necessary” for detailed structural characterization.
