Waste-​glass recycling: A step toward microwave applications

International audienceThis study deals with microwave properties of glass foams prepd. from glass industrial waste. Two types of cullets (one from soda-​lime silicate glasses and the other from cathodic ray tubes - CRT) have been combined with different foaming agents (C, SiC, AlN)​. Glass foams electromagnetic properties are primarily detd. by their apparent d. as well as by the nature of the foaming agent. Foams, blown with carbon as foaming agent, present high dielec. loss and could be used as green electromagnetic absorbent in building industry
