Molybdenum electrode

Material Properties

Molybdenum has a melting point of 2610ºC, a boiling point of 5560°C, a density of 10.2g/cm³,and it is insoluble in water and belongs to the fifth period element, with an atomic radius of 139pm and an electronegativity of 2.16. It is a silvery white shiny metal in appearance. It has good electrical and thermal conductivity, low expansion coefficient and high strength at high temperature (1100 ~ 1650 ℃). Compared with tungsten, it is easy to process.

Craftsmanship

Raw Material

Starting from raw materials, we select high-quality raw materials, which is very prominent in the stability and consistency of products. Identify different brands of raw materials and mark the batch number. And each batch of raw materials shall be sampled, inspected and archived. Ensure the traceability of each finished product and continuously improve the product quality.

Milling

The control of the milling process of Mengchang Metal products is very accurate, with several large mixers and vibration platforms to ensure that the materials in the pulverizing and mixing process can be fully stirred and evenly distributed, so as to ensure the internal organization consistency of the products.

Suppress

In the process of powder compacting, the powder is pressed by isostatic pressing equipment to make its internal structure uniform and dense. Mengchang has very perfect batch mold, and also has isostatic pressing equipment to meet the production of ultra-large batches of products.

Sinter

In powder metallurgy, after the metal powder is formed by isostatic pressing, it is heated at a temperature lower than the melting point of the main components to make the particles connect, so as to improve the performance of the products, which is called sintering. After the powder is formed, the dense body obtained by sintering is a kind of polycrystalline material. The sintering process directly affects the grain size, pore size and grain boundary shape and distribution in the microstructure, which is the core process of powder metallurgy.

Forging

The forging process can make the material obtain higher density, better mechanical properties, and play a role in strengthening the surface. Accurate control of the processing rate and forging temperature of tungsten and molybdenum materials is an important factor for the superior performance of Mengchang tungsten and molybdenum materials. A processing method of using a forging machine to apply pressure to a metal blank to plastically deform it to obtain a forging with certain mechanical properties, certain shape and size.

Rolling

The rolling process makes the metal material produce continuous plastic deformation under the pressure of the rotating roll, and obtain the required section shape and properties. With advanced tungsten and molybdenum cold and hot rolling technology and equipment, from tungsten and molybdenum metal blank to the production of tungsten and molybdenum foil, mengchang guarantees you more advanced production technology and superior metal properties.

Heat-Treat

After the forging and rolling process, the material is subjected to the heat treatment process to completely eliminate the internal structural stress of the material, give play to the material performance, and make the material easier for subsequent machining. Mengchang has dozens of vacuum furnaces and heat treatment hydrogen furnaces to meet the rapid delivery of mass production orders.

Machining

The material of Mengchanghas undergone complete heat treatment, and then processed into various customized sizes by machining equipment such as turning, milling, cutting, grinding, etc., and ensures that the internal organization of tungsten and molybdenum materials is tight, stress-free and hole-free, which can meet the needs of customers.

Quality Assurance

Quality inspection and control will be carried out from raw materialsand for each steps of the production , so as to continuously ensure the quality every product. At the same time, when finished products are delivered from the warehouse, the appearance, size and internal organization of materials are tested one by one. Therefore, the stability and consistency of products are especially prominent.

Chemical Composition

The main component of molybdenum electrode is molybdenum, which is made by powder metallurgy process. Due to it’s advantages of high temperature strength, good high temperature oxidation resistance, long service life, corrosion resistance and not easy to stain glass, it is widely used in daily glass, optical glass, thermal insulation materials, glass fiber, rare earth industry and other fields.

Working principle of molybdenum electrode

High-purity molybdenum is used as the negative pole of the battery, and oxygen is used as the positive pole. With the aqueous solution of sodium hydroxide or potassium hydroxide as the electrolyte, generally, molybdenum will absorb oxygen in the air when it reacts, and a chemical reaction will occur in the process of battery discharge, and molybdenum will react with oxygen to form molybdenum oxide.
