Lithium chromate (Li₂CrO₄) is an inorganic ceramic compound combining lithium oxide with chromium oxide, belonging to the class of chromate ceramics. While primarily known as a laboratory chemical and research material, it appears in specialized applications requiring chromium-based oxidizing properties, including use as a corrosion inhibitor in protective coatings, a component in certain glass formulations, and as a precursor in materials synthesis. This compound is notable within the chromate family for its high lithium content, which can influence thermal behavior and chemical reactivity compared to heavier-metal chromates, though it is less commonly specified in high-volume engineering applications than more established ceramic phases.
