Oxidation Behavior of MgO‐C Refractories Containing Metallic Aluminum, Calcium Magnesium Aluminate Aggregates, and Carbores P

open access: yessteel research international, Volume 96, Issue 5, May 2025.
The study investigates the oxidation resistance of MgO‐C refractories enhanced with calcium magnesium aluminate (CMA) aggregates, metallic aluminum, and Carbores P from 800 to 1600 °C. CMA retains resistance up to 1200 °C but decreases above. Carbores P protects up to 1000 °C, while metallic aluminum shows the highest resistance across the range.
