DEOXIDIZER AND PROCESS OF PRODUCING DEOXIDIZER

摘要

A deoxidizer for absorbing and removing oxygen from the surrounding atmosphere, comprising oxygen-deficient cerium oxide having a powder form with a specific surface area of 0.6 m²/g or less or the form of a formed body with a specific surface area of 3.0 m²/g or less. The deoxidizer reacts with oxygen even in a moisture-free atmosphere, does not trigger a metal detector nor heat up when microwaved in a microwave oven, and is prevented from abruptly reacting with oxygen and igniting even when brought into direct exposure to the air. The deoxidizer is therefore suited for oxygen removal, for example, inside food packages.
