orthotitanate

Orthotitanate is a chemical compound with the general formula M4TiO4, where M represents a monovalent cation. These compounds are salts of orthotitanic acid, H4TiO4. The structure typically involves a titanium atom in a +4 oxidation state coordinated by four oxygen atoms, forming a tetrahedral TiO4 unit. The remaining valency is satisfied by the monovalent cations. Common examples include potassium orthotitanate (K4TiO4) and sodium orthotitanate (Na4TiO4). These materials are often crystalline solids and their properties can vary depending on the specific cation present. Orthotitanates can be synthesized through various methods, often involving the reaction of titanium oxides or alkoxides with the corresponding metal hydroxides or carbonates at elevated temperatures. They find applications in areas such as ceramics, catalysts, and as precursors for other titanium-containing materials due to the stable Ti(IV) oxidation state. Their reactivity and thermal stability are key factors in their industrial utility.
