Product Overview

 

Manganese trioxide is a black tetragonal crystal belonging to the spinel class, with an ionic structure of Mn2+(Mn3+) 2O4, in which divalent and trivalent manganese ions are distributed at two different lattice positions. Oxygen ions are tightly packed in cubic form, divalent manganese ions occupy tetrahedral voids, and trivalent manganese ions occupy octahedral voids. When the temperature is below 1443K, manganese trioxide transforms into a tetragonal spinel structure; Above 1443K is a cubic spinel structure. Manganese trioxide is paramagnetic at room temperature, but exhibits ferromagnetism below 41-43K. Manganese trioxide exists in the form of black manganese ore in nature and is the most stable oxide. Relative density 4.7, melting point 1567 ¡ãC insoluble in water, soluble in hydrochloric acid.

The preparation methods of manganese trioxide mainly include the following: high-temperature calcination method, wet catalytic oxidation, electrolysis method, and chemical precipitation method.


Technical Parameter

Appearance:Brown powder

Diameter:-25μm

 

Product Features

Stability: Manganese trioxide is relatively stable at room temperature and is not easily decomposed, which makes it very reliable as a catalyst in many chemical reactions.

Catalytic performance: Manganese trioxide can catalyze various hydrogenation reactions, such as hydrogenation of styrene to phenylethane, hydrogenation of propylene to propanol, etc.

High purity and low impurities: High quality manganese trioxide products have high purity, low metal impurity content, uniform particle size distribution, and large specific surface area, making them particularly suitable for the preparation of positive electrode materials for lithium-ion batteries.

Widely used: Manganese trioxide is mainly used in the production of soft magnetic materials and lithium positive electrode materials, such as manganese zinc ferrite and lithium manganese oxide in lithium-ion batteries.

 

Application Fields

 

Battery material: Used as a positive electrode material for lithium-ion batteries, it can improve the capacity and cycling performance of the battery. In lithium-ion batteries, the unique structure and electrochemical properties of manganese trioxide contribute to improving the charging and discharging performance and stability of the battery

Electronic materials: used for making magnetic cores, magnetic recording materials, etc. In the field of electronics, as a magnetic core material, it can provide good electromagnetic performance.

Catalyst: A catalytic process that participates in some chemical reactions, such as hydrogenation reactions.

Soft magnetic materials: Manganese trioxide is one of the important raw materials for preparing soft magnetic materials such as manganese zinc ferrite, and is widely used in fields such as electronic computers, telephone transformers, and commercial inductors.

Handy
Size: 4" - Black, Style: Open Hooks
I use an ocean container for storage and have some things that need to be hanging. These are perfect for any place you are unable to drive nails. I bought the stronger ones and have had no problems. Ordered more after trying them.

Work great
Item Package Quantity: 6, Color: Black
Relatively strong hooks. The metal I have them on is thin so the magnets arent as steady as I hoped but thats my fault not the hooks. Ample hook space and solidly built

You need these!
Item Package Quantity: 4, Color: Black
These are not really “industrial strength” but they work great and are decent quality, especially for the price. I bought them to use on a sheet metal barn and they hold halters, rakes and other supplies with ease. Out of curiosity I did toss a dewalt drill in one and it held even though I ordered the medium size and the drill didn’t fit super well.
