| 摘要 |
The present invention relates to a gas adsorption material which can avoid degradation of gas adsorption performance while reducing the amount of combustible gas generation, and a vacuum heat insulation material including the gas adsorption material. The gas adsorption material comprises at least one of Li, V and Zr, or an alloy including the same metal, has nitrogen absorbability, includes a metal deactivated by moisture as an adsorptive component of nitrogen, and further comprises an additive material for the metal, wherein the metal is attached to the particle surface of the additive material. The metal may be an alloy of Li with an alkaline earth metal, such as a Ba-Li alloy. The additive material has water absorbability and may be at least one selected from the group comprising inorganic oxides, transition metals, oxides of transition metals, alloys containing transition metals and mixtures containing transition metals. |
