Description

this tube type because of several specific advantages over metals such as tantalum, molybdenum, and nickel. The radiating area of graphite is approximately twice the projected anode area be- cause of its surface porosity and it will dissipate at least four times more heat than metal, Graphite, being infusible will not warp or twist.
