A graphite electrode is a type of electrode used in electric arc furnaces (EAFs) to melt and refine steel, iron, and other metals. It is made of graphite, a form of carbon that has unique properties such as high thermal conductivity, high melting point, low coefficient of thermal expansion, and good electrical conductivity. Graphite electrodes are essential components in the production of high-quality steel and are widely used in the metalworking industry.
Graphite electrodes are typically cylindrical in shape and range in size from 75 to 700 millimeters in diameter and 1 to 2 meters in length. They are installed in EAFs to conduct electric current and generate heat to melt and refine metal. When an electric current passes through the graphite electrodes, it generates an electric arc, which produces temperatures of up to 3,500�°C (6,332�°F). This extreme heat melts the metal in the furnace and allows impurities to be removed, resulting in a high-quality end product.
Graphite electrodes are chosen for EAFs due to their high electrical conductivity, low electrical resistance, and excellent thermal shock resistance. They are also relatively easy to shape and mold, which allows them to be manufactured in various sizes and shapes to meet the specific needs of different industries. The quality of graphite electrodes is determined by factors such as their electrical resistivity, flexural strength, thermal expansion coefficient, and oxidation resistance.

Application
UHP (Ultra High Power) Graphite Electrodes are primarily used in electric arc furnaces for steel production. They are suitable for high-temperature and high-power applications and are used to melt steel scrap and other materials. UHP graphite electrodes are also used in the production of ferroalloys, silicon metal, and other non-ferrous metals. In addition to their primary use in the steel industry, UHP graphite electrodes can be used in other industrial applications that require high-temperature and high-power capabilities, such as in the production of electrodes for electric discharge machining (EDM) or for heating elements in high-temperature furnaces.
Activated carbon (also known as active carbon or activated charcoal), is an artificial carbonaceous (carbon-rich) material. It is typically made from wood, but also can be made using bamboo, coconut husk, peat, woods, coir, lignite, coal, pitch, and other dense carbon sources. There are a variety of similar substances that fall under the general classification of activated carbon such as activated coal and activated coke, but they all share the properties of vast surface area per mass, exceptional microporosity, and a composition of almost exclusively elemental carbon.
The pore structure of activated carbon can be seen with an electron microscope and is primarily responsible for its usefulness. Microscopes show a surface honeycombed with holes and crenelated with ridges which join to a similar structure deeper within the carbon. Due to this structure, a pound of activated carbon, for instance, can have as much as 100 acres of surface area packed into it. These small, low-volume pores allow for increased adsorption capacity (the process of chemical surface bonding, not to be confused with absorption) and allow more reactions between the carbon and other media. Activated carbon is therefore highly valued in filtering, deodorization, medical, and chemical applications, as most contaminants easily bind to it and remain trapped in the carbon microstructure via many small distance-dependent atomic attractions (known as London dispersion forces).
Because carbon is produced through a relatively inexpensive and simple series of activation processes, it is widely available for applications; however, activated carbon must be constantly changed as it becomes clogged with contaminants, water, and becomes a breeding ground for dangerous microorganisms after a certain contact time. This means activated carbon is constantly produced to meet the demands of its uses and is kept in large supply to ensure no delay exists in the replacement process.
How to Make Activated Carbon
The production process of activated carbon, or the activation of carbon, exists in two forms. A carbonaceous source such as wood, coal, peat, or any organic carbonaceous material is carbonized, which means the pure carbon is extracted by a heating method known as pyrolysis. Once the material is carbonized, the material needs to be oxidized or treated with oxygen either by exposure to CO2 or steam or by an acid-base chemical treatment. The sections below will briefly detail these processes.
Coal-based Activated Carbon with Powder
Powdered activated carbon (PAC) is a fine black powder that is produced by heating carbon-rich materials, such as coal, wood, or coconut shells, in the absence of air to create activated carbon. PAC is widely used in various applications, including water treatment, air purification, gas processing, and industrial processes.

In water treatment, PAC is added to the water to remove organic contaminants, such as pesticides, solvents, and pharmaceuticals, as well as taste and odor-causing compounds. The PAC particles attract and adsorb these contaminants, effectively removing them from the water. PAC is also used in wastewater treatment to remove dissolved organic compounds and color from the wastewater.

In air purification, PAC is used to remove pollutants, such as volatile organic compounds (VOCs), from the air. The PAC particles adsorb these pollutants, effectively reducing their concentration in the air.
Granular Activated Charcoal
Granular Activated Charcoal (GAC) is a highly porous form of activated carbon that is used in a wide range of applications, including water and air purification, gas and vapor adsorption, and chemical and pharmaceutical processing. It is produced by heating carbon-rich materials, such as coconut shells or wood, in the absence of air, which creates a highly porous material with a large surface area.
The surface area of GAC can range from 500 to 1500 square meters per gram, depending on the specific production process and the pore size distribution. This high surface area and porosity give GAC excellent adsorption properties, allowing it to attract and retain a wide range of organic and inorganic compounds.
GAC is commonly used in water treatment applications, where it is used to remove impurities such as chlorine, volatile organic compounds (VOCs), pesticides, and other organic contaminants. It can also be used to remove odors and flavors from water.
Honeycomb Activated Carbon
Honeycomb activated carbon is a type of activated carbon that is structured in a honeycomb shape. It is commonly used in air and water purification due to its high surface area and pore volume, which allows it to effectively adsorb impurities and pollutants. The honeycomb structure also provides excellent flow characteristics, making it ideal for use in filtration systems.
