Radiation Changes in the Optical and Mechanical Properties of SiO2-Based Materials

It is shown that radiation changes in the mechanical and optical properties of quartz glasses are of the same nature and are associated with the electric charge separation in the nano-inhomogeneous glass volume. The electric charge separation in glasses occurs up to the absorbed doses of the order o...

Description
Summary:It is shown that radiation changes in the mechanical and optical properties of quartz glasses are of the same nature and are associated with the electric charge separation in the nano-inhomogeneous glass volume. The electric charge separation in glasses occurs up to the absorbed doses of the order of 1 MGy. The local separation of the electric charge due to the appearance of Coulomb forces leads to radiation Coulomb hardening of glasses and composites on their basis.
