    摘要: The preparation, structure, and properties of solid inorganic materials containing at least one transition element, aluminum, boron and oxygen are described. Also described is the use of such materials in catalytic compositions for the conversion of organic compounds. In particular, new materials comprising(a) crystalline LnAl.sub.1.67+0.67X (B.sub.4 O.sub.10)O.sub.X, and(b) crystalline LnAl.sub.2.67+0.33Z (B.sub.4 O.sub.11)O.sub.Zwhere Ln is at least one transition element, X is a number ranging from 0 to 1, and Z is a number ranging from 0 to 2, each crystalline phase having a characteristic X-ray diffraction pattern are described as well as the use of such materials in various catalyzed processes including oxidative dehydrogenation of hydrocarbons and oxygen-containing hydrocarbons, dehydrogenation to functionalize alkylaromatic compounds, and ammoxidation of alkylaromatic compounds. Also, these new crystalline rare earth aluminum borates exhibit a variety of physical properties that make their use as optical materials attractive, including uses for optical frequency conversion, fluorescence, and laser materials.
