HC-1, carrying noble metal palladium (Pd), has double-functional deoxidizing mechanism: catalytic reaction deoxidizing and chemical reaction deoxidizing. The former is suitable for deoxidizing from H2 and inert gases such as add H2 to N2 for deoxidizing; The latter is suitable for directly deoxidizing from inert gases such as N2. Attribute to Pd , the reactivity temperature of HC-1 is very low, therefore, it is fit for large scale industry production. Deep deoxidizing, good mechanical strength, long useful life, good thermal resistance are also its remarkable characters.
