Vacuum Furnace Applications
Due to the material's remarkable thermal properties, graphite is an excellent material to consider when doing vacuum furnace applications. This is mainly attributed to the material's innate ability to maintain its structural and molecular integrity when exposed to extreme heat. Graphite has an incredibly high melting point. Technically it does not melt, but sublimates into a gas at a certain number of atmospheres. Graphite transfers heat very well, and exhibits minimal expansion when heated.
As a result, graphite materials are frequently used to make trays, racks, shelving, baskets, carrier systems, and various holders or fixtures for heat treating, brazing, and sintering applications. For these particular applications, a high thermal conductivity and a low CTE [coefficient of thermal expansion] are important, and Ohio Carbon Blank has several premium grade materials with these characteristics.
Materials rated at or above 100 W/m°K and have CTE’s as low as 2-3 microns per degree Fahrenheit:
