Manganese Oxide Powder

Updated: 2026-08-06

Overview

Manganese oxide powder, primarily composed of manganese(II) oxide (MnO), is a crucial industrial chemical with diverse applications. It is commonly produced through the reduction of higher manganese oxides or thermal decomposition of manganese carbonate. The powder is valued for its stability, reactivity, and versatility in various chemical processes. In the B2B sector, manganese oxide powder is traded in bulk quantities, with specifications such as purity (typically 90-99%) and particle size (ranging from 1 to 100 microns) being critical for buyers. Its green to brown appearance makes it easily identifiable, though its properties can vary slightly based on manufacturing methods.

Physical and Chemical Properties

Manganese oxide powder exhibits a high melting point of 1,945°C, making it suitable for high-temperature applications. Its density of 5.43 g/cm³ indicates a relatively heavy material, which is insoluble in water but dissolves in acids, forming manganese salts. The powder is known for its oxidizing properties, often used in redox reactions. Thermal stability is a standout feature, allowing it to be used in ceramics and refractory materials. The particle size distribution affects its reactivity and suitability for specific applications, with finer powders being more reactive. Its color can range from green to brown, depending on impurities and oxidation states.

Main Applications

Manganese oxide powder is extensively used in the ceramics industry as a colorant and flux, contributing to the durability and aesthetic qualities of tiles and pottery. In agriculture, it serves as a micronutrient in fertilizers, promoting plant growth. The battery industry utilizes it in dry cell batteries, particularly in alkaline and zinc-carbon types. Additionally, it is a key component in animal feed supplements, ensuring proper manganese levels for livestock. Chemical synthesis often employs manganese oxide as a catalyst or precursor for other manganese compounds. Its role in water treatment and environmental remediation is also noteworthy, where it aids in removing contaminants.

Safety and Storage

Handling manganese oxide powder requires caution due to potential health risks. Inhalation of dust can cause respiratory issues, and skin contact may lead to irritation. Appropriate personal protective equipment (PPE), such as gloves, masks, and goggles, is essential during handling. Storage should be in a cool, dry, and well-ventilated area, away from incompatible substances like strong acids or reducing agents. Containers must be tightly sealed to prevent moisture absorption and contamination. Spills should be cleaned promptly using appropriate methods to avoid dust generation.

B2B Procurement Guide

When procuring manganese oxide powder, B2B buyers should prioritize suppliers with certifications such as ISO or GMP to ensure quality and consistency. Key specifications to verify include purity levels (e.g., 98% or higher), particle size distribution, and absence of heavy metal contaminants. Bulk purchasing often offers cost advantages, but buyers should assess logistics and storage capabilities. Sample testing before large-scale orders is recommended. Price fluctuations can occur based on manganese ore market trends, so staying informed about raw material costs is beneficial for negotiation.
