A statistical model is proposed to address the problem of two-phase coexistence near the morphotropic phase boundary (MPB) in Pb(${\mathrm{Zr}}_{1\mathrm{\ensuremath{-}}\mathit{x}}$${\mathrm{Ti}}_{\mathit{x}}$)${\mathrm{O}}_{3}$ solid-solution series. Functional forms for the molar fractions of tetragonal and rhombohe…
Just before the turn of this century, physicists were impressed with their abilities to explain many of the basic laws of the universe mathematically.However, the energy output spectrum of a heated black body resisted rigorous explanation, particularly at the shorter wavelengths.This failure of classical physics was r…

Plasma etching in conjunction with scanning and analytical transmission electron microscopy was used to characterize the microstructure and microchemistry of silicon carbide sintered with yttrium‐aluminum garnet (YAG). The SiC grains comprise a core/rim structure with small amounts of excess yttrium, aluminum, and oxy…
In the present paper a review is made about the works and researches related to the use of superficial protectants for the stones conservation in Spain. It deals with the parameters and durability tests most frequently used in laboratories, in order to foretell the suitability of the different treatments. It is also p…
This paper presents the state-of-the-art on hydraulic behaviour of the blast furnace slags. It analyzes different aspects such as characteristics and influence of its vitreous phase structure, its chemical composition, mechanisms that rule its hydration process, activators and activating process mechanisms, etc. At th…
The present paper deals with the influence that the addition of calcareous "fillers" to a Portland cement has on the mechanical resistances of its mortars. Taking as a basis a Portland cement to which calcareous "fillers", from 0 up to 50 percent, are added, test tubes of standardized mortars were prepared. After 7, 2…
