“…Calcium aluminates (also known as high alumina cements) have a rich phase diagram which includes five lime-alumina compounds -3CA, 12C7A, CA, C2A and C6A [13,14,15,16,17,18,19,20,21,22,23]. Among them, 12C7A has the lowest melting point (1722…”

“…Such a superior refractory properties of these materials make them attractive for various applications as ceramics and glasses as well as in cement and steel industries [24,25]. Calcium aluminates have been grown by several techniques including solid state reactions (sintering), sol-gel technologies and self-propagating combustion synthesis, see [22,23,24] and references therein.…”

First-principles electronic band structure investigations of five compounds of the CaO-Al2O3 family, 3CaO•Al2O3, 12CaO•7Al2O3, CaO•Al2O3, CaO•2Al2O3 and CaO•6Al2O3, as well as CaO and α-, θ-and κ-Al2O3 are performed. We find that the conduction band in the complex oxides is formed from the oxygen antibonding p-states and, although the band gap in Al2O3 is almost twice larger than in CaO, the s-states of both cations. Such a hybrid nature of the conduction band leads to isotropic electron effective masses which are nearly the same for all compounds investigated. This insensitivity of the effective mass to variations in the composition and structure suggests that upon a proper degenerate doping, both amorphous and crystalline phases of the materials will possess mobile extra electrons.

“…Table I-6 summarizes the physical and chemical characteristics of some cementitious phases prepared by chemical synthesis routes [125][126][127][128][129][130][131][132][133][134][135][136][137]. Ye'elimite was prepared by Song et al [125] using chemical synthesis from calcium nitrate, aluminium nitrate and aluminium sulfate.…”

“…Here we report the preparation of a LDH precursor with Eu 3+ in the hydroxide layer by coprecipitation, and calcination of it to produce a loose powder material, Ca 3 Al 2 O 6 :Eu 3+ , in which the activator Eu 3+ is hosted in the lattice of Ca 3 Al 2 O 6 . It has been known that Ca 3 Al 2 O 6 has infrared transmission up to 6 mm [22,23] and has never been reported as a host for phosphors.…”
