Glasses have a wide range of technological applications. In particular, glasses produced by vitrification technology are used to immobilize hazardous wastes, such as radioactive or chemical products because of the small volume of the resulting waste-form, and the large number of elements that can be incorporated in the glass structure with potentially high durability. Almost any melted substance, if cooled sufficiently fast, can be made as a glass. However, crystallization may occur when slow cooling rates or suitable nucleation centers are found, degrading many of the properties required for the glass. Here, we propose to image crystallized regions within glass specimens by performing energy dispersive neutron radiography experiments with the MCP detector. For contrast, we plan to exploit the differences in the total cross section of glasses and crystals on neutron wavelength.
