Foamed Glass Resists Neutrons

The foam consists of titanium, zirconium and chromium oxides added to a mixture of glass and the foaming agents carbon and silicon carbide. Tests were carried out for three and a half days in a nuclear reactor during which the foams were subjected to neutron streams of 1018 neutrons per sq. cm. showed that the materials do not change in strength. The information is also given in this digest.
