Graphite Heating Systems

Graphite Heating Systems ensure that precise power input to each zone of the susceptor is achieved by varying either or both the overall power level and the amount of time power is switched to a particular zone of the coil during each power distribution cycle of the system.

Induction Heating: Applications

Susceptor Heating A susceptor is a conductive metal material that is used to transfer heat to another piece of metal or non-conductive material. Susceptors are often made from graphite because it is highly resistive and very machinable, or alternatively from

Graphite

The thermal processing of graphite is not a simple operation, often requiring zoned induction heating coils and multiple output power supplies to manage ultra-high temperatures. Maintaining the desired temperature profile within the susceptor is critical in achieving optimum productivity.

radius of the coil and the height of the susceptor on heating condition in the vertical MOCVD reactor. Al-though vertical reactors heated by induction with the coils around the outside wall are widely used, the heat-ing in the graphite susceptor is non-uniform of the

What is Induction Heating and How do Induction Coils

Induction heating is an accurate, fast, repeatable, efficient, non-contact technique for heating metals or any other electrically-conductive materials. An induction heating system consists of an induction power supply for converting line power to an alternating current and delivering it to a workhead, and a work coil for generating an electromagnetic field within the coil.

Susceptor Heating

Graphite is frequently used as a susceptor because it offers machinability, high resistivity (ideal for induction), and a temperature range up to 3000 C (5430 F). Susceptors can also be made from Molybdenum, Silicon Carbide, Stainless Steel, Niobium, Aluminum, and other conductive materials.

Numerical Study of Heating Structure in Cold

On the traditional heating structure of MOCVD reactor, the temperature distribution of substrate is nonuniform, which goes against the film growth. This paper focuses on the numerical calculation of the heating structure, by using SiC and graphite as the materials of the new susceptor and coupling with multifields. By adjusting the position and size of each of the ring body of graphite in the
