Manganese Tetroxide Powder (Mn₃O₄)

Product Overview

Manganese Tetroxide (Mn₃O₄) is a black tetragonal crystal belonging to the spinel structure, with an ion arrangement of Mn²⁺(Mn³⁺)₂O₄. The divalent and trivalent manganese ions are distributed at different lattice sites, with oxygen ions densely packed in a cubic arrangement. Mn₃O₄ exhibits paramagnetism at room temperature and shows ferrimagnetic properties at lower temperatures. Its high stability and resistance to decomposition make it a commonly used catalyst. In nature, it is found in the form of the mineral "hausmannite." Mn₃O₄ has a high melting point and relatively high density, contributing to its robustness in various applications.

Key Features

• Stability: Manganese Tetroxide is stable at room temperature, making it ideal for use as a catalyst in various chemical reactions.
• Catalytic Properties: Mn₃O₄ is an effective catalyst for hydrogenation reactions, such as the hydrogenation of styrene to ethylbenzene and propylene to propanol.
• High Purity and Low Impurities: High-quality Mn₃O₄ has low metal impurity content and uniform particle size, ensuring it meets the demands of high-precision applications.

Applications

• Battery Materials: Mn₃O₄ is used as a cathode material for lithium-ion batteries, improving battery capacity, cycle performance, and charging/discharging efficiency.
• Electronic Materials: As a magnetic core material, Mn₃O₄ provides excellent electromagnetic properties and is widely used in electronic devices, including transformers and inductors.
• Catalysts: Mn₃O₄ is widely used in catalytic processes, especially in hydrogenation reactions, to enhance reaction efficiency.
• Soft Magnetic Materials: It is used in the production of manganese-zinc ferrites and other soft magnetic materials for use in electronic computing and telephone transformers.
