Abstract：Foam glass was prepared with sintered process, using moderate amount of additives and thepowder of waste stiff glass-fiber as main material and its foaming mechanism was investigated. Itsfoaming mechanism is that some gas given off from foaming agents, is confined and therefore manysmall bubbles are formed in the brick of foam glass due to sintering. Because of softening of the glassand expansion of the bubbles at foaming temperature, the glass block begins to enlarge and to formfoam glass. Proper bubble stabilizers, binders and increasing pressure in the brick forming processmake sintering speed up and be in favor of the formation and stabilization of the bubbles.
