Exploring the Applications and Varieties of Thick Molybdenum Wire: A Guide to Characteristics and Selection Criteria

Thick molybdenum wire typically refers to wires with a larger diameter or cross-sectional size. The thickness can vary depending on the specific application requirements. It is available in a range of diameters, from relatively thin 0.35mm to relatively thick 4.0mm, and the choice of thickness depends on the intended use and the properties needed for that application.

The moly wire has characteristics such as high melting point, excellent strength and rigidity, good electrical conductivity, high temperature resistance and corrosion resistance. The specific characteristics can vary based on the alloy composition and processing techniques used to manufacture the wire.

Thicker molybdenum wires are often utilized in applications where increased strength, durability, or heat resistance is essential. Some applications may require thicker wires to carry higher currents, withstand more significant mechanical stress, or serve as structural elements in specialized equipment.

Black molybdenum wire, cleaned molybdenum wire and redrawing molybdenum wire are usually called thick molybdenum wire. Their types can be Mo1, MoLa, MoAl, and MoY, and are mostly as parts of electric vacuum and electriclight source; materials for electrical heating, such as support leader and grid, etc. Redrawing molybdenum wire is mostly used for processing thin molybdenum wire. 

When considering molybdenum wire for a particular application, factors such as the operating environment, temperature conditions, electrical conductivity requirements, and mechanical properties will influence the choice of wire thickness. It's important to consult with manufacturers who can provide guidance on selecting the appropriate thickness based on the specific needs of the application.

Silicon Carbide Rods Are Used in Various Types of Electric Industrial Furnaces Thanks to its Characteristics

As a new type of electric heating element, silicon carbide rods are widely used in various types of electric industrial furnaces. The main composition of this rod is silicon carbide that is an artificial abrasive. Generally, silicon carbide is divided into black silicon carbide and green silicon carbide. The later one owns greater purity.  

In addition to being used in the abrasive industry, silicon carbide is used in the electrical industry to produce silicon carbide electric heating elements - silicon carbide rods, which have the characteristics of electrical conductivity, heat conduction, and long service life.

Antioxidant properties of silicon carbide rod

After the silicon carbide rod is heated by electricity, the temperature will rise rapidly. Generally, in the air, when the temperature of the rod body reaches 800 degrees Celsius, the surface of the rod begins to undergo oxidation reaction. As the temperature continues to rise to 1000 to 1300 degrees Celsius, the heating part of the silicon carbide rod will react with air to produce carbon dioxide and silicon dioxide. Silica will condense on the surface of the rod to form a dense protective film.

When the temperature of the rod body continues to rise to about 1550, the thickness of the protective layer will become thicker due to the continuous production of silicon dioxide, which can isolate the silicon carbide rod from the air, which is effective for the formation of the rod body, thereby starting to reduce the oxidation rate. However, the silicon dioxide protective layer also has a certain melting point. If the rod body continues to heat up to more than 1600 degrees, the silicon dioxide protective film will be destroyed due to the excessive temperature and fall off and other reactions, and then the oxidation rate of the silicon carbide rod will resume. 

This situation should be avoided as much as possible during use, and the structure of the resistance furnace or industrial electric furnace should be designed reasonably. Pay attention to the position of the rod body during the installation to avoid excessive local temperature or other electrical conditions during use. Mistakes cause the temperature of the silicon carbide rod to be too high, which greatly reduces the service life of the rod body.

Characteristics of Molybdenum Ore in China

Characteristics of molybdenum ore in China include low grade, rich accompanying useful components, high economic value, large scale and open cut mining, and high degree of geological works.

Low Grade

Molybdenum ore in China has large proved reserves, but with low grade compared with the main molybdenum resources countries in the world, most of which belong to low-grade deposits. For the low-grade deposits with average grade less than 0.1%, its reserves account for 65% of the total reserves, of which less than 0.05% account for 10%, medium grade (0.1%～0.2%) account for 30%, higher grade (0.2%～0.3%) account for 4% and the average grade higher than 0.3% only account for 1%.

Rich Accompanying Useful Components and High Economic Value

According to the statistics, molybdenum, as a single mineral deposit, its reserves only account for 14% of the total reserves in China; as the main mineral resources, it is associated with other useful mineral deposits, which account for 64% of the total reserves; others that are associated and coexisted copper, tungsten and tin and other metals account for 22%.

Large Scale and Open Cut Mining

According to statistics, reserves of large molybdenum ore with more than 100 thousand tones account for 76% of the total reserves; the medium-sized deposits with 10,000 tones to 100,000 tones of reserves account for 20%; molybdenum deposits that are suitable for open cut mining account for 64%. Most of large deposits can open cut mining and particles of molybdenite are coarser, which are easy to choose.

On the ore type perspective, the proven reserves of molybdenum ore in China are mainly composed of molybdenum sulfide ore that is easy to use, which account for 99% of recoverable deposits. Oxided molybdenum ore and mixed molybdenum ore that are not easy to be used and unknown molybdenum ore only account for 1%.

High Degree of Geological Works

Exploratory reserves after geological works account for 50.5% of the total recoverable deposits, 41.8% when in the detailed survey. When in the detailed survey, the reserves account for 92.3% of total recoverable deposits in China.
