Calcium peroxide (CaO₂) is an inorganic ceramic compound belonging to the peroxide family, characterized by its layered crystal structure and moderate elastic stiffness. It is primarily used in environmental remediation, water treatment, and soil stabilization applications where it acts as an oxygen source and oxidizing agent, particularly in bioremediation of contaminated groundwater and sediments. CaO₂ is also explored in healthcare contexts (wound dressing, dental applications) and as a bleaching agent in industrial processes; engineers select it over alternatives like hydrogen peroxide or permanganate when sustained, controlled oxygen release and chemical stability in solid form are required.
