WebGraphite heating elements are brittle, inexpensive, possess low resistivity, and have a low expansion coefficient. They do no degrade from thermal cycling; however, they require higher operating currents and are susceptible to contamination due to open porosity. Graphite elements may be coated to improve operating characteristics. WebAs graphite emerged as a highly engineered advance material, the use of this material in manufacturing hot zone components increased. Along with advanced material design the vacuum furnace manufactures made efforts to reduce the size shape and weight of the hot zone components to increase efficiency.
