Abstract

In this study, glass abrasive sludge was utilized for a light weight material and graphite was used as expanding agent. The glass abrasive sludge with added expanding agent was formed into pellet by a pelletizer. When glass abrasive sludge is made as pellet, water glass is added as a binder(water : water glass = 8 : 2). The pellet was sintered at $700\~800^{\circ}C$ by rotary kiln composed of 4 segment temp. system. The absorption ratio of lightweight materials tended to increase in proportion to increasing content of graphite. The lowest value of specific gravity that was observed in this study was $1.8\%$.
