Crucible

In chemistry, a crucible is a kind of laboratory equipment that is usually a small cup, about the size of a shot glass, made of porcelain or non-reactive metal. Crucibles are used to heat chemical compounds to very high temperatures using a gas burner. One of the earliest uses of platinum was as a material in crucibles. Metals such as nickel and zirconium are also used as a modern crucible material.

  Title: Crucible used in Czochralski method * Desc: This crucible was used to pull a silicon crystal by Czochralski method. Generally, the crucible breaks at the end of the process. Some amount of silicon rests always on the bottom after the process. We can also observe a color modification of the crucible and a texture on the crucible walls. * Author: Twisp * Date: 25.08.2005

  Title: Crucibles used in Czochralski method * Desc: Two unused crucibles - smaller one is placed in the big crucible, which is not the case during the crystal growth process. Only one crucible is placed in the crystal puller. A piece of polysilicon is placed on the bottom. * Author: Twisp * Date: 24.08.2005
