| 摘要 |
An object of the invention is to provide a container for holding a melt of a metal and/or a melt of a metal salt, in which a melt container allows keeping a small amount of heat radiation of the melt, suppressing penetration of the melt and development of breakage or cracking to the minimum, holding the melt suitably, and also preventing the melt from impurity contamination. The melt container of the invention is a container for holding the melt of the metal and/or the melt of the metal salt, and has, sequentially from 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 800° C.) of 4 W/m·K or less, and a third layer constituted of a refractory having a higher thermal conductivity than thermal conductivity of the second layer.
