Formation and evolution of Spinel in aluminum killed
The results showed that spinel inclusions are first formed in liquid steel after desulfurization and by the reaction between dissolved aluminum in liquid steel and MgO in the ladle slag. These inclusions were modified by calcium to both liquid and solid calcium aluminates. Also observed after calcium treatment was the formation of MgO

A STUDY ON SPINEL FORMATION AND SINTERING BEHAVIOR
The success of neutral ramming mixes in steel melting induction furnaces depends critically on the formation of in situ spinel during service. A better understanding of spinel formation and sintering kinetics is essential for designing Alumina based Al 2 O 3-MgO spinel forming dry vibrating mixes for induction furnace linings with

Matrix microstructure optimization of alumina-spinel
Jan 01 2018 · The spinel phases in specimens calcined at 1200 °C and 1300 °C presented no definite borders or shapes and had a diameter of 0.1 µm. However in the specimen calcined at 1450 °C the diameter of spinel grain size grew up to 1.2 µm and SP-CA cement showed a denser structure. (2) Spinel-alumina castables were fabricated with SP-CA cements.
