For professionals in the chemical industry, understanding the fundamental properties of key raw materials is the bedrock of successful product development and manufacturing. Manganese Dioxide (MnO2), identified by its CAS number 1313-13-9, is one such critical compound. Its unique chemical and physical characteristics make it indispensable across a spectrum of industrial applications, from energy storage to coloration. As a prominent manufacturer and supplier of high-quality chemicals, we are pleased to provide a comprehensive overview of Manganese Dioxide and guide you on sourcing this essential material.

Manganese Dioxide (MnO2) is an inorganic compound that typically presents as a dense, black or dark brown powder. Naturally occurring as the mineral pyrolusite, it is the most abundant ore of manganese. Synthetically produced MnO2, which we offer, often exhibits a brownish tone and is processed to meet stringent industrial purity standards. Key physical properties include a density of approximately 5.03 g/cm³ and a melting point of 535 °C. Its insolubility in water and most common acids (like nitric and sulfuric acid) contributes to its stability in various formulations and environmental conditions. These properties are fundamental to its widespread use as a pigment, catalyst, and active component in electrochemical devices.

Chemically, Manganese Dioxide is known for its oxidizing capabilities. It can readily react in various oxidation-reduction processes. For example, in battery applications, it acts as a cathode material, accepting electrons to facilitate electrochemical reactions. Its ability to react with potassium hydroxide in the presence of oxygen to form potassium permanganate is another demonstration of its chemical reactivity. For manufacturers looking to buy Manganese Dioxide, understanding these chemical properties is crucial for predicting its behavior in specific applications, such as its role as a depolarizer in dry cell batteries or as a catalyst in chemical synthesis. The specific MnO2 content, often ranging from 35% to over 75% as indicated in technical specifications, directly impacts its performance in these roles.
