mercury cell

PX675 type mercury batteries are only needed for the light meter.

Mercury batteries used to be common but have become increasingly restricted.

The power supply for the instrumentation was provided by mercury batteries.

Some advantages of mercury batteries are their very long life and steady voltage.

In 1954, mercury batteries were included in the standard.

It is also used as a material for cathodes for mercury batteries.

At the base of the cone a ring of mercury batteries provided power.

Formerly, mercury batteries were made in this size.

Mercury batteries of the same dimensions are no longer manufactured because of their toxicity.

The exposure meter uses a PX625 mercury battery, which is now discontinued.

A different form of mercury battery uses mercuric oxide and cadmium.

A mercury battery is a primary cell.

Mercury batteries also supply a stable voltage, but are now banned in many countries due to their toxicity and environmental impact.

It is used in mercury batteries.

Furthermore, the mercury battery has a life span of several years, compared to a few months for the alkaline battery.

The Electro 35 was designed to operate using a 5.6V mercury battery but these have now been banned due to environmental concerns.

Mercury batteries are very similar to silver-oxide batteries.

During World War II he came up with the sealed mercury battery that led to many advances in military technology.

Formerly, mercury batteries were made as button cells (types MR44 and NR44).

(Older hearing aids often used mercury battery cells, but these cells have become banned in most countries today.)

The mercury battery is a non-rechargeable electrochemical battery, a primary cell, that was common throughout the middle of the 20th century.

They are expensive because they contain silver, but do not have toxic mercury like the cheaper mercury battery.

The Greatbatch innovation varied from the earlier Swedish devices in using primary cells (mercury battery) as the energy source.

Due to the content of mercury, and the resulting environmental concerns, the sale of mercury batteries is banned in many countries.

Silver-oxide and lithium batteries are popular today; mercury batteries, formerly quite common, are no longer used, for environmental reasons.

The mercury cell process continues in use to this day.

Mercury cells have very long shelf life, up to 10 years.

The salt being needed to feed a new installation of mercury cells at the Staveley works.

Currently there are around 12 000 tonnes of mercury sitting in mercury cells in Europe.

'That he was experimenting with mercury cells.

Sodium amalgam is a by-product of chlorine manufactured by mercury cell electrolysis.

Allied Chemical and Dye Corporation began the production of chlorine by mercury cell in 1950.

"Phototronics: Latest word on mercury cell replacements and rechargeable AA's."

This electrolysis is conducted in either a mercury cell, a diaphragm cell, or a membrane cell.

Mercury cell chlor-alkali plants produce chlorine and caustic using mercury cells.

The batteries (two PX 675 type mercury cells) were only needed for the CdS light meter.

In 1942 Samuel Ruben and Mallory developed the mercury cell which was considered a break through in battery manufacturing.

This installation lasted into the late 1950s when the cellroom at Staveley was replaced with German-made mercury cells.

The mercury cell was effectively banned in most countries in the 1990s due to concerns about the mercury contaminating landfills.

As a result, diaphragm methods produce alkali that is quite dilute (about 12%) and of lower purity than do mercury cell methods.

Because of concerns about this mercury escaping into the environment, the mercury cell process is generally being replaced by plants which use a less toxic cathode.

Mercury cell chlor-alkali production is a significant user of mercury and a source of mercury releases to the environment.

A mercury cell electrolysis and hydrolysis of the amalgam with sodium hydroxide leads to sodium gallate.

While the mercury cell method produces chlorine-free sodium hydroxide, the use of several tonnes of mercury leads to serious environmental problems.

Due to these concerns, mercury cell plants are being phased out, and a sustained effort is being made to reduce mercury emissions from existing plants.

As electrodes in some types of electrolysis, batteries (mercury cells), sodium hydroxide and chlorine production, handheld games, catalysts, insecticides.

Mercury cell electrolysis, also known as the Castner-Kellner process, was the first method used at the end of the nineteenth century to produce chlorine on an industrial scale.

In 1962, Dryden Chemical Company began operating a chloralkali process plant in Dryden, Ontario using mercury cells.

A mercury battery (also called mercuric oxide battery, or mercury cell) is a non-rechargeable electrochemical battery, a primary cell.

The airborne emissions of mercury continued unabated until the company stopped using mercury cells in its chloralkali process in October 1975; the company closed down in 1976.
