    摘要： There is provided a C12A7 compound capable of selectively and reversibly clathrating X− ions, such as active oxygen radicals, with improved controllability. The C12A7 compound clathrating OH− ions and On− at a concentration of 2×1019 cm−3 or less can be prepared by subjecting a mixed material containing Ca and Al to a solid phase reaction at a firing temperature not lower than 1200° C. and lower than 1449° C. in a dry oxygen atmosphere having an oxygen partial pressure of 0.1 atm or more and a water vapor partial pressure of 10−3 atm or less, keeping the resultant product at a temperature of 1200° C. or higher, and cooling rapidly. The C12A7 compound is heat-treated to clathrate OH− ions at a concentration of 2×1019 cm−3 or less, and On− at a high concentration of more than 2×1019 cm−3. The compound can reversibly clathrate or release On− ion radicals through the elevation or lowering of the temperature thereof in a temperature range of 300 to 850° C. The compound is useful for an oxidation catalyst, an anti-bacterial agent, an ion conducting material, an electrode for a solid-electrolyte fuel cell, and the like.

    摘要： A structurally modified alumina useful as a catalyst support, or heat transfer solid for fluidized bed synthesis gas processing. A Group IIA metal, or metals, particularly magnesium and barium, is composited with a particulate alumina to provide a catalyst support, or alumina heat transfer solid, having increased resistance to sintering and agglomeration; properties which promote defluidization of the bed in conducting fluidized bed reactions at high temperatures. The particles of preference are represented by formulas (1) and (2), a composite particle being represented by formula (1), as follows:M.sub.x Al.sub.2 O.sub.3+x (1)with the core of the particle being represented by formula (2), as follows:M.sub.y Al.sub.2 O.sub.3+y (2)where in formulas (1) and (2) M is a Group IIA metal, x is a number ranging from about 0.01 to about 0.4 and is representative of the number of moles of the metal M per mole of Al.sub.2 O.sub.3 y is a number equal to or greater than zero, and x is greater than y.

    摘要： A method for obtaining aluminum oxide where the smelted metallurgical slag is subjected to a slow cooling and then self-decomposition by simultaneous action of ultrasound or vibration of high frequency, carried out, which accelerates the formation, in a glassy (vitrous) phase, of a polymorphous, crystalline, high-temperature modification of calcium aluminate, 12 CaO.multidot.7Al.sub.2 O.sub.3, which can be easily lixiviated with aqueous solutions of soda. From lye liquors after extraction, the aluminum oxide is then recovered and the residue, after lixiviation, is burnt to standard portland clinker keeping possibly the lowest proportion of the quantity of clinker produced in relation to the quantity of obtained aluminum oxide.
