Metals Cast on Twin-Belt Continuous Casting Machines: Copper (Bar, Strip, Anode), Aluminum(Strip), Zinc (Strip), Lead (Strip)
The first form of magnetron tube, the split-anode magnetron, was invented by Albert Hull in 1920, but it wasn't capable of high frequencies and was little used.
The electrodes are connected to a high voltage A.C. source (typically 6,600 volts to 13,800 volts){If D.C. voltage is used Electrolysis of water occurs decomposing water into its elements H2 at the cathode(-ve electrode) and O2 at the anode(+ve electrode)}.
The Bohnenberger electrometer, developed by J.G.F. von Bohnenberger, consists of a single gold leaf suspended vertically between the anode and cathode of a dry pile.
Silicon has been considered as an anode material because it supports larger amounts of lithium-ion intercalation.
Ryaztsvetmet offers a selection of lead powder and feathered tin, solder alloys, Babbitts, lead pipes and goods (anodes & wires)
In 1937, Alan Blumlein originated a configuration between a "triode strapped" tetrode and normal tetrode, that connects the extra grid of a tetrode to a tap from the OPT part way between the anode voltage and the supply voltage.
Philips-branded sets and most store brands use an offset, with the longer anode (positive lead) being lower and the shorter cathode (negative lead) being higher on the wedge base.
Eccles invented the term Diode to describe an evacuated glass tube containing two electrodes; an anode and a cathode.
