Kinetics and Mechanism of Oxidation Induced Contraction of MgAl2O4 Spinel Carbon Composites Reinforced by Al4C3in situ Reaction
Kinetics and mechanism of oxidation induced contraction of MgAl 2 O 4 spinel carbon composites reinforced by Al 4 C 3 in situ reaction were researched in air using vertical high temperature thermal dilatometer from 25 °C to 1 400 °C. It is shown that oxidation induced contraction of MgAl 2 O 4 spine...
