ABSTRACTThe feasibility of NiO-MoO3reaction as a complement for the self-healing reaction proposed in our previous study is assessed in high-temperature aqueous environment. NiMoO4·nH2O and crystal α-NiMoO4are produced in an aqueous environment by Ni(OH)2-MoO3and NiO-MoO3reactions, of which the starting temperature is about 100°C. NiMoO4·nH2O is completely dehydrated into β-NiMoO4when annealed at about 600°C in air. Therefore, NiO-MoO3reaction is expected to self-heal the cracks as a supplement of Fe2O3-MoO3reaction in the high-temperature aqueous environment.
