Chemical corrosion mechanisms of magnesia–chromite

The results showed that the overall wear rate of the fingers was very low with the exception of the aluminabased brick made of fused corundum and magnesia–alumina spinel and the magnesiabased brick made of sintered magnesia and zircon addition In all refractory types new phases were formed as a result of slagrefractory interactions

Thermodynamic calculation and microstructure

2022212 The spinel diffraction peaks in CCAMC samples were weaker than that in CCAMC samples The addition of carbon coated alumina changed the contact mode of magnesia and alumina in CCAMC samples which inhibited the direct contact between the magnesia and alumina and caused a weaker spinel diffraction peaks Download Download highres image
