Abstract It is well-known that production of a crystal matrix is as a rule accompanied by using hightemperature processing which considerably limits the area of applied use of the objects. In the present work, we consider new approaches aimed at formation of crystalline highly active oxide phases without using annealing stage by achieving deep intercomponent penetration of disperse particles at the nanolevel during the sol-gel process reactions. The use of these approaches was possible in a single stage for the first time: 1) entrapment of various biological objects in a ceramic biocompatible matrix necessary for obtaining vaccines of new generation; 2) doping a crystal lattice up to 10at. % usingsoft chemistry method; 3) chemical modification of biopolymers for the purpose of developing high-level operational characteristics. In this work, trends in forming crystals from solutions for existing ceramic matrices are analyzed for the first time. The main objects of study are materials of modified titania and alumina.
