Ingot

Note: There is also a computer certificate called INGOT.

Gold ingots from the Bank of Sweden

Ancient Copper ingot from Zakros, Crete. The ingot is shaped in the form of an animal skin, a typical shape of copper ingots from these times

An ingot is a mass of metal or semiconducting material, heated past its melting point and then cast into a shape which is easy to handle, often a bar or block. Additionally, ingots may be molds from which metal objects are cast.

In the semiconductor industry single crystal ingots (often called boules) of semiconductor materials can be grown by methods such as the Czochralski process or Bridgeman technique. These are then cut up and polished to provide wafers on which semiconductor devices, ranging from microprocessors to light-emitting diodes can be fabricated.

'Single crystal ingots can be created with single dendrite formation. Such is done for single crystal turbine blades.' (by Reid Wilson)
