摘要: Segregation in crystals results surface layer enrichment of selected lattice elements. The present work considers the phenomenon segregation solid solutions TiO2 doped with donor-type elements, such as niobium and tantalum. focus is on effect oxygen activity at elevated temperatures. It shown that segregation-induced may be used for engineering oxide materials general TiO2-based particular controlled composition required to achieve desired reactivity photoreactivity energy conversion solar particular. development related procedures requires correct determination during processing concentration gradients within layer.
