    • occlude To shut up; close.
    • occlude In physics and chem., to absorb: specifically applied to the absorption of a gas by a metal, such as iron, platinum, or palladium. particularly at a high temperature. Thus, palladium heated to redness and cooled in a current of hydrogen absorbs or occludes over 900 times its volume of the gas. By this means the physical properties of the metal are changed, and the occluded hydrogen is regarded as existing in a solid form as a quasi-metal, called hydrogenium, the specific heat, specific gravity, and electrical conductivity of which have been approximately determined. Probably a part of the gas forms also a definite chemical compound with the metal. Occluded gases also occur in meteorites. Thus, the Arva meteoric iron yielded (Wright) 47 volumes of the mixed gases carbon dioxid, carbon monoxid, hydrogen, and nitrogen.
