Lithium chromate is a chemical compound that has the chemical formula Li2CrO4. It is a salt of lithium and chromic acid, with a basic structure of Li+-O-Cr+-O-Li+. The hydroxyl group on the chromium atom makes it soluble in water. Lithium chromate is an ionic compound that undergoes phase transitions to form solids and solutions at various temperatures. Lithium chromate can be synthesized by reacting potassium dichromate, magnesium salt, and dimethyl fumarate with lithium carbonate or lithium hydroxide. The product has been shown to have toxicological properties in animal studies.

Lithium Chromate is a yellow, odorless powder used as a corrosion inhibitor, heat transfer agent, and oxidizing agent in leather and metal finishing. It is also used in photography, wood preservatives, batteries, safety matches and cement.
