Foam Glass

foam glass

[′fōm ‚glas] (materials) A light, black, opaque, cellular glass made by adding powdered carbon to crushed glass and firing the mixture.

Foam Glass

a cellular material that is obtained by heating to fusion finely ground glass powder with a pore-forming material, such as coke, chalk, or dolomite. It is a good thermal and acoustic insulator and is easily worked and cemented. The average density varies from 100 to 700 kg/m³.

Foam glass is used for the thermal insulation of refrigeration cars and underground piping and as a buoyant material in rescue devices and pontoons. Filters for acids and alkalies are made from foam glass with open pores.

foam glass, cellular glass, expanded glass

A thermal insulation made by foaming softened glass to produce many sealed bubbles; has a closed-cell structure. Molded into board and blocks, usually with a density of about 9 to 10 lb per cu ft (14.4 to 16 kg per cu m).
