The development of the varistor, in form of a new type of rectifier based on a cuprous oxide (Cu 2 O) layer on copper, originated in the work by L.O. Grondahl and P.H. Geiger in 1927. [3] The copper-oxide varistor exhibited a varying resistance in dependence on the polarity and magnitude of applied voltage. [4]
Compared to later silicon or germanium devices, copper-oxide rectifiers tended to have poor efficiency, and the reverse voltage rating was rarely more than a few volts. A number of rectifier discs would need to be used in series to provide an adequate reverse breakdown voltage figure – a bridge rectifier for a 12V battery charger would often ...
The strength of metal oxide adhesion effectively determines the wetting of the metal-oxide interface. The strength of this adhesion is important, for instance, in production of light bulbs and fiber-matrix composites that depend on the optimization of wetting to create metal-ceramic interfaces. [ 1 ]
Thermistor or varistor symbol [2] ... In materials such as nickel oxide (NiO) with lithium ... aluminum, copper brass or plastic and configurations include threaded ...
Metal oxide varistors typically have lower resistance as they heat up; if connected directly across a power bus, for protection against voltage spikes, a varistor with a lowered trigger voltage can slide into catastrophic thermal runaway and sometimes a small explosion or fire. [23]
Copper oxide is any of several binary compounds composed of the elements copper and oxygen. Two oxides are well known, Cu 2 O and CuO, corresponding to the minerals cuprite and tenorite, respectively. Paramelaconite (Cu 4 O 3) is less well characterized. [1] Copper oxide may refer to: Copper(I) oxide (cuprous oxide, Cu 2 O) Copper(II) oxide ...
A mother lamented her stolen heirloom jewelry and the dismantling of the family cabin piece by piece until every inch had been sold off. Addicts stripped so many houses, barns, and churches of copper and fixtures in one Kentucky county that the sheriff formed a task force.
As a significant product of copper mining, copper(II) oxide is the starting point for the production of many other copper salts. For example, many wood preservatives are produced from copper oxide. [3] Cupric oxide is used as a pigment in ceramics to produce blue, red, and green, and sometimes gray, pink, or black glazes. [3]
