High density graphite elements are brittle, inexpensive and machined conventionally from large blocks, therefore very large sized elements can be produced in a variety of shapes and sizes.

This material has a low expansion coefficient and is not degraded by constant heating and cooling. Uncoated it is not suitable for UHV due to its open porosity (10-20%), and particle contamination can also be a problem. Its low resistivity means it requires high current power supplies and therefore large feedthroughs and cables which can be expensive.

It can operate up to 2000 °C in an inert atmosphere, 1800°C in vacuum and <;500°C if oxygen is present. Deposition product can cause electrical shorts and thus problems with supporting weak sagging element designs.

Graphite heating element for crystal pulling and fiber optic cable drawing,high density spark graphite along with fine grain size ensures uniform heating & control of temperature profile.

This high strength material can be used to a smaller cross section to increase the electrical resistance of the element thus reducing the current consumption. Onsec also offers graphite heating rods and accessories for vacuum furnaces.
