· TiO

Titanium monoxide (TiO) is a ceramic compound belonging to the transition metal oxide family, characterized by a rock-salt crystal structure and notable hardness combined with metallic-like electrical conductivity. While less common than TiO₂ (titanium dioxide), TiO is primarily of research and specialized industrial interest, particularly valued in applications requiring materials that bridge ceramic hardness with enhanced electrical and thermal transport properties. Its applications span high-temperature structural components, wear-resistant coatings, and emerging electronics where the interplay between ceramic strength and semiconducting behavior is advantageous.
