Conclusions
It is shown that the adhesion of the coating made from suspensions based on silica sol and vitreous silica reaches 1 MPa; the adhesive strength of the coating increases with the concentration of SiO2 in the silica sol; the temperature interval between 100 and 300°C is optimal for the formation of the coating.
The electrical nature of the adhesion of the coating made from suspensions based on silica sol and vitreous silica has been discovered; the possibility of using dielectric measurements to monitor the forming of the adhesive join and of forecasting its strength has been established.
The refractory coatings made from suspensions based on silica sol and vitreous silica have been tested and recommended for use at the Cherepovetsk Metallurgical Combine.
