Studies of the corrosion of an unfired tank bIock made from highly siliceous clay

GT V01 1960 155-161

 A highly siliceous unfired ('Rodur') tank block with an alumina content of about 11% has been successfu1ly used in a two-year furnace campaign for the melting of borosilicate glass. Reference is made to the working conditions under which a cord-free hard glass could be melted in the Rodur tank. The material underwent an intensive chemical, physical and x-ray examination after use and an explanation for the surprisingly good durability was found.
