· MnO

Manganese monoxide (MnO) is a ceramic semiconductor compound belonging to the transition metal oxide family, commonly found in rock salt crystal structure with antiferromagnetic properties below its Néel temperature. Industrial applications include use as a pigment in ceramics and glass, a component in ferrite magnetic materials, and an additive in battery cathodes and catalytic systems. Engineers select MnO for applications requiring moderate mechanical stiffness combined with electrical semiconductivity, particularly in magnetic device manufacturing and electrochemical energy storage where manganese oxides offer cost-effectiveness and environmental advantages over some alternatives.
