Manganese and electrolytic manganese powder

 It is easier to become rust than iron. If in moist air, it will soon become gray and lost its luster. There is a layer of manganese oxide on surface. Melting point of manganese is lower than iron. And its mechanical strength is weaker than steel, while the price is much more expensive than steel. So there is less production of manganese powder and most manufactures would like to produce steels.

Manganese is the most important use is the manufacture of alloys manganese steel. 2.5-3.5% of manganese steel, obtained low-manganese steel is simply too brittle like glass, a knock on the pieces. However, if you join more than 13% of the manganese powder, made of high manganese steel, then it becomes hard and resilient. High-manganese steel heated to a pale orange, become very soft, very easy to perform various processing. In addition, it is not magnetic, will not be attracted by the magnet. Now, a lot of people use manganese steel to manufacture steel mill, ball bearings, the bulldozer and excavator bucket often grinding components, as well as tracks, bridges, etc.. In military affairs, made of high manganese steel helmets, tanks, steel armor, and armor-piercing warheads. Refining manganese steel, manganese up to 60-70% of soft tin and iron ore mixed with smelting from. In addition to manganese steel, manganese steel is also important manganese alloy and manganese steel containing 30% manganese, with good mechanical strength.

Another important compound is manganese, potassium permanganate. Potassium permanganate is a purple needle-like crystals. Add a little potassium permanganate, would be sufficient to make a big bucket of water into the purple. Potassium permanganate is a strong oxidant, bactericidal. Next to the mug in public places, often placed a bucket of violet disinfection of water, in fact, this is the solution of potassium permanganate, the concentration of one-thousandth. However, this water can not drink into the stomach, gastric lavage agents used in medicine as emetic role. In the analysis of chemical, potassium permanganate is used as oxidants, known as the potassium permanganate method is to use it as titrant for chemical analysis. Potassium permanganate is restored, often into the manganese dioxide. Gray manganese water after use, the bottom usually black scum, and that is manganese dioxide.

Manganese powder refining calorimetry and electrolysis are two kinds of heat production purity of not more than 95 to 98 percent pure manganese powder Electrolytic preparation, purity of 99.7 to 99.9 percent. Now, the electrolytic method of production has become the main form of manganese powder production. Electrolytic Manganese is the acid leaching of manganese ore manganese salt, sending the electrolytic cell electrolytic precipitation of elemental metal. Look like iron, irregular flakes, hard and brittle, side light, the other side is rough, silver-white to brown, silver gray processed into powder after; easily oxidized in the air, when dissolved in the case of dilute acid and the replacement of hydrogen, slightly higher than room temperature, biodegradable water and release hydrogen.

Electrolytic manganese powder has high purity. Its role is to increase the hardness of co-metal materials. The manganese-copper alloy and manganese aluminum alloy have most widely applications. Manganese of these alloys can improve tensile strength, toughness, wear resistance and corrosion resistance. The electrolytic manganese powder is used in the production of stainless steel. There are two manganese powder production methods for metal powder suppliers. One of them is electrolysis and it obtains electrolytic manganese metal powder. While the other one is to use manganese and silico-manganese silicon alloy as raw materials in desilication refining production method. The manganese metal powder will be produced. Manganese powder is generally used as alloy additives of melting high-quality low-carbon steel and alloying agent of non-ferrous alloys.Source:http://www.mhcmp.com
