WIPO Patent Application WO/2011/086809
Kind Code:
A1
Abstract:
A melt container that holds a melt of a metal and/or a melt of a metal salt therein is provided in which heat dissipation from the melt is slight and melt penetration and breakage or cracking are minimized. The container can not only satisfactorily hold the melt therein but also be prevented from causing contamination of the melt with impurities. The melt container is a container for holding a melt of a metal and/or a melt of a metal salt, and is characterized by including, disposed in the following order from the inside of the container, a first layer constituted of a refractory having an apparent porosity of 12% or less, a second layer constituted of a refractory having a thermal conductivity at 800ºC of 4 W/m·k or less, and a third layer constituted of a refractory having a higher thermal conductivity than the second layer.
