Production of MgO/TiC Composites From MgO‐C Recyclates Using Spark Plasma Sintering

open access: yesAdvanced Engineering Materials, Volume 28, Issue 10, 20 May 2026.
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.

Liquidus of MgO and MgAl2O4 in the CaO‐MgO‐Al2O3 System at 1550 and 1600°C

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 5, May 2026.
ABSTRACT In this study, the liquidus of MgO and MgAl2O4 spinel phase in the CaO‐MgO‐Al2O3 system at 1550 and 1600°C were experimentally investigated using a classical quenching method. In order to examine the liquidus composition accurately, the equilibration was carried out using four different ways using the combinations of Pt and ceramic (MgO and ...
