Heterogeneous sol-gel systems (suspensions), synthesized by mixing sols and fillers of various dispersity (oxides, minerals, etc.), are successfully used to prepare glass-ceramic coatings. Sol composition (precursor, catalyst, solvent, dopants), filler dispersity and a homogenization mode for obtained suspensions essentially influence the properties of coatings formed. Here ways of the control of properties of heterogeneous sol-gel systems (by using various dopants, additives of organic low- and high-molecular compounds, as well as ultrasound) to reach set electro-physical and mechanical characteristics of coatings are considered in details. A number of examples of applications of glass-ceramic and hybrid coatings as well as ‘skin’ - layers are resulted.
