Influence of the host lattice on the blue color development in Ni2+, La3+ co-doped calcium aluminates: Choice not chance

open access: yesBoletín de la Sociedad Española de Cerámica y Vidrio
The influence of (Ca2+ + Al3+) → (La3+ + Ni2+) substitution on the color of calcium aluminates (Ca3Al2O6, CaAl2O4, CaAl4O7, CaAl12O19) obtained by combustion synthesis represented the focus of this work. The maximum temperature recorded during combustion

Effect of Two Therapeutic Renal Diets on Hormonal and Regulatory Pathways Affecting Calcium Homeostasis in Cats With Early‐Stage Chronic Kidney Disease

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Chronic kidney disease (CKD) is a known risk factor for hypercalcemia in cats. Phosphate‐restricted diets have also been implicated in causing hypercalcemia, in part because phosphate restriction increases the Ca:P ratio. The primary objective of this study was to evaluate the impact of two different therapeutic renal foods on ionized (iCa ...

Co-existence of a Cr3+ phase (CaAl2Cr2O7) with hydraulic calcium aluminates at high temperature in the Al2O3-CaO-Cr2O3 system

open access: yes, 2021
Obtaining a stable Cr3+ phase at higher temperatures in the presence of hydraulic calcium aluminates (the phases found in calcium aluminate cement, CAC) in the Al2O3-CaO-Cr2O3 system remains a significant challenge in many application areas, as the ...

Formation of calcium aluminates in the lime sinter process. [Extraction of alumina from fly ash]

open access: yes, 1980
A study of the formation of several calcium aluminates from pure components in the lime sinter process was undertaken to determine the kinetics of formation and subsequent leaching using a dilute sodium carbonate solution. The composition CaO 61.98%, SiO/

Synergistic Effect of Ladle Furnace Slag and Biomass Bottom Ash in Alkali‐Activated Binders

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 7, July 2026.
This study investigates the synergistic co‐activation of ladle furnace slag (LFS) and biomass bottom ash (BBA) in alkali‐activated binders. Results indicate that 75 wt% BBA maximizes mechanical strength, reaching 11.1 MPa in compression after 90 days. Amorphous silica from BBA acts as a chemical buffer, mitigating slag expansion while forming a stable ...

Molecular Dynamics Simulations of γ‐Belite(010)–Water Interfaces With High‐Dimensional Neural Network Potentials

open access: yesChemistry – A European Journal, Volume 32, Issue 24, 23 June 2026.
Several γ$\gamma$‐belite(010)–water interfaces have been studied by molecular dynamics simulations using a high‐dimensional neural network potential. The structure and reactivity of interfacial water have been analyzed and two types of surface defects could be identified, which indicate the possible existence of a wide range of surface structures ...

An investigation into the Traditional Method of Production of Omani Sarooj

open access: yesSultan Qaboos University Journal for Science, 1999
In the past, sarooj had been used as the basic cementing material with which the A flaj system (the irrigation system used in Oman) was built. Worldwide, materials like sarooj existed and were known for their good impermeability and long durability.
