Graphite

Graphite manufacturers hold their own in the refractory world, where the graphite they sell is used to build kiln and blast furnace bricks. It is also used to produce crucibles, ladles and moulds for holding molten metals. Graphite flake is one of the most commonly used materials in the manufacturing of refractories made for the continuous casting of steel. With graphites extremely high melting point, a manufacturer cannot go wrong by catering to the chemical industry.

Graphite is used in such high-temperature processes as the production of phosphorus and calcium carbide in arc furnaces. It is also used to conduct electricity in some aqueous electrolytic processes like the production of halogens like chlorine and fluorine. High purity electrographite is well-suited to the nuclear industry because of its low absorption of neutrons, high thermal conductivity and maintained strength at high temperatures.

For many furnaces and other high-temperature applications, Thermic Edge can offer parts made from extruded graphite. Although slightly lower in strength than ISO Graphite, Extruded Grades are nonetheless ideally suited for many applications including furnace heating elements, fixtures and furniture, susceptors, moulds, crucibles and sintering trays & boats. Extruded graphite is also widely used as a cathode or anode material in a wide variety of electrolytic cell applications.

The silicon is purified, put into a crucible with other elements then melted at a very high temperature. A silicon rod is placed on the surface of the molten silicon in the crucible, and then pulled and rotated to form a monocrystalline ingot.

Applications: Monocrystalline silicon pulling (known as the Czochralski technique, and sometimes called CZ pulling)

In ion implantation, the ion beam collisions expose metal components to high amounts of wear. Graphite shields are used to protect such components.
