ingot

 
Dictionary: in·got   (ĭng'gət) pronunciation
 
n.
  1. A mass of metal, such as a bar or block, that is cast in a standard shape for convenient storage or shipment.
  2. A casting mold for metal.

[Middle English, mold for casting metal : probably in-, in; see in–2 + Old English goten, past participle of geotan, to pour, or perhaps from Old French lingot, metal ingot (reinterpreted as l'ingot : le, the + *ingot, ingot).]

Gold in bar form.

Investopedia Says:
Gold held in the vaults of banks and brokerages are usually in the form of ingot.


 

Bar of metal. The Federal Reserve System's gold reserves are stored in ingot form. Individual investors may take delivery of an ingot of a precious metal such as gold or silver or may buy a certificate entitling them to a share in an ingot.

 

Mass of metal cast into a size and shape such as a bar, plate, or sheet convenient to store, transport, and work into a semifinished or finished product. The term also refers to a mold in which metal is so cast. Steel ingots range in size from small rectangular blocks weighing a few pounds (or kilograms) to huge, tapered, octagonal masses weighing more than 500 tons (450 metric tons).

A mass of molten metal which has been poured into a mold to solidify; it differs from a casting in that it requires rolling or forging to become a finished or semifinished product.


 

[Ar]

A shaped mass of smelted but unworked metal. The shape and size of ingots are determined by custom rather than function, although their weight may be related to the capacity of the means by which they were commonly moved about. Where ingots from a particular source are of standard size and weight they can thus be used as currency for trade. See ox-hide ingot, currency bar.

An ingot is a material, usually metal, that is cast into a shape suitable for further processing.[1]

Additionally non-metallic and semiconductor materials in prepared in bulk form are also sometimes referred to as ingots.

Uses

Ingots require a second procedure of shaping, such as cold/hot working, cutting or milling to produce a useful final product.

Additionally ingots (of less common materials) can be used as currency, or as a currency reserve.

Types of ingots

Metal

Metal heated past its melting point and cast into a bar or block using a mold. Additionally, the molds from which metal objects are cast may be called ingots.

Non-metallic ingots

Polycrystalline and single crystal ingots are made from semiconductor materials by pulling from a molten melt. Uses include the formation of photovoltaic cells by cutting the ingot into flats.

Single crystal ingots

Single crystal ingots (called boules) of materials are grown (crystal growth) using methods such as the Czochralski process or Bridgeman technique.

The boules may be either semiconductors—for the electronic industry, or non-conducting inorganic compounds for industrial and jewelry use, e.g., synthetic ruby, sapphire etc.

Single crystal ingots of metal are produced in similar fashion to that used to produce high purity semiconductor ingots[2], i.e. by vacuum induction refining. Single crystal ingots of engineering metals are of interest due to their very high strength due to lack of grain boudaries. The method of production is via single crystal dendrite and not via simple casting. Possible uses include turbine blades.
