Neutral compounds of the group 13 elements are electron deficient, so they are generally moderately strong acids. In contrast to groups 1 and 2, the group 13 elements show no consistent trends in ionization energies, electron affinities, and reduction potentials, whereas electronegativities actually increase from aluminum to thallium.
This work produced a type of barium alumino-silicate-based ceramsite (BASC) from bauxite, coal gangue, and barite. The influence of raw material composition and sintering temperature on the physical and mechanical properties, microstructure, and pore structure of the ceramsite were investigated.

Bauxite Ore Processing. Aluminum is found in varying amounts in nature as aluminosilicates (contains aluminum, silicon, and oxygen) in various types of clay. As the minerals are weathered they gradually breakdown into various forms of hydrated aluminum oxide, Al 2 O 3.xH 2 O, known as bauxite. The bauxite is purified by the Bayer Process. First ...
