Web·PGS Graphite Sheet carries the heat rapidly due to high heat conductivity ·PGS Graphite sheet has high cooling effect . Inspection 1 The heat transfer was monitored with thermograph after the heater was attached to the lower part of PGS, Copper and Aluminum. Size;18x180x0.1mm [Measuring method] WebHeater Element A graphite cathode heater presents numerous advantages over swaged-tantalum or refractory-wire heaters. The work function of graphite, 5.0 eV, is higher than those of the refractory metals18and it is therefore less likely to act as a secondary cathode during heater operation, thus discouraging plasma attachment to the heater. food grants ontario

Graphite occurs naturally and is the most stable form of carbon under standard conditions. Synthetic and natural graphite are consumed on large scale (300 kton/year, in 1989) for uses in pencils, lubricants, and electrodes. Under high pressures and temperatures it converts to diamond. It is a good (b… food granule function
