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.
