A complex sol-gel method – CSGP (Polish Patent 172618) was used to synthesize silica glasses for immobilizing high-level radioactive waste. The role of radioactive elements was played by Cs, Sr, Co – added in the form of nitrates, while neodymium was a surrogate for actinides. As a result of hydrolysis and polycondensation reactions taking place in a solution containing tetraethoxysilane and metal nitrates, where ascorbic acid served as a catalyst, gels were obtained in the form of powders and compacts.
