Production of MgO/TiC Composites From MgO‐C Recyclates Using Spark Plasma Sintering
Advanced Engineering Materials, EarlyView.Using the spark plasma sintering technique, MgO/TiC composites are manufactured from recycled MgO‐C refractories stemming from the steel production that were mixed with titanium powder. This article shows, how the size of the Ti grains and their distribution in the powder mixture affect the local carbon concentration in TiC.

Zirconia-spinel composites. Part I: synthesis of powders and dense materials [PDF]
, 2000 MgAl2O4 and x wt% ZrO2–MgAl2O4 (1 # x # 30) composite powders were prepared by the urea combustion route. The powders were further ground by either ball milling or attrition to refine the grain size.

A Comprehensive Assessment and Benchmark Study of Large Atomistic Foundation Models for Phonons
Advanced Intelligent Discovery, EarlyView.We benchmark six large atomistic foundation models on 2429 crystalline materials for phonon transport properties. The rapid development of universal machine learning potentials (uMLPs) has enabled efficient, accurate predictions of diverse material properties across broad chemical spaces.

Optical constants of refractory oxides at high temperatures
, 2013 Many cosmic dust species, among them refractory oxides, form at temperatures higher than 300 K. Nevertheless, most astrophysical studies are based on the room-temperature optical constants of solids, such as corundum and spinel. A more realistic approach

Sessile dissociation in the stoichiometric spinel MgAl2O4
Journal de Physique, 1979 Dislocations in spinel, MgO. nAl2O3, are dissociated out of their glide planes and precise determinations of the dissociation planes by stereographic analysis are reported. It is shown that for stoichiometric spinel (n = 1), the numerous, long and straight, edge dislocations left by a small strain on { 110 } glide planes, are dissociated in the { 110 }
