Calcium perchlorate is classified as a metal perchlorate salt with the molecular formula Ca(ClO₄)₂. It is an inorganic compound that is a yellow-white crystalline solid in appearance. As a strong oxidizing agent, it reacts with reducing agents when heated to generate heat and products that may be gaseous (which will cause pressurization in closed containers). Calcium perchlorate has been categorized as having explosive reactivity. Ca(ClO₄)₂ is a common chemical on the soil of planet Mars, counting for almost 1% of the Martian dust, by weight.
