Phase diagrams of system UO2-ZrO2-SiO2 are analysed. It is shown that lava-like fuel containing materials (LFCM) may include the metastable inclusion of another phases which can have essential influence on the main physical properties of LFCM. The possibility of application of different optical methods for determination of changes of local symmetry caused by including of nanoparticles is studied. Magnetic and dielectric properties of LFCM are investigated taking into account influence of anisotropy of field and peculiarities of temperature dependences. The main physical phenomena which effect on the charging of submicron dusty particles of radionuclides are analysed. The effects of self-charging of dusty particles as result of its beta-activity are analised; the relaxational processes are investigated. The effective methods of numerical modelling of behaviour of fine-disperse systems are proposed and developed taking into account interaction with external fields. The original algorithm of numerical solution of motion equation for dusty particles of submicron size is proposed. Taking into account shifted flows of media, external magnetic and gravitation fields. The modelling of processes of adsorption on the surface of alpha-quartz are performed. The processes of adsorption of molecules H2, H2O as well as ions of uranil on the SiO2 surface are investigated. It is shown that during adsorption the hydrolysis of water and destroying of hydrogen molecules into atoms. The analysis of coefficients of adsorption of ions on the surface of LFCM is performed in the wide interval of change of surface charge density and concentration of electrolyte. The value of penetrating strengthen for various type of LFCM are estimated. The various methods of dusty filtration are analysed. It is denote the perspective of quasielectrostatic air filters.
