Influence of Basic Oxides Ratio Li₂O/Al₂O₃, SiO₂/Al₂O₃ and H₂O/Al₂O₃ on Physical, Rheological and Colloidal-Chemical Properties of Lithium Containing Alumosilicate Suspensions in the System xLi₂O-Al₂O₃-nSiO₂-mH₂O

Abstract:

The influence of the main structure-forming oxides Li₂O/Al₂O₃, SiO₂/Al₂O₃ and H₂O/Al₂O₃ on the physical, rheological and colloidal-chemical properties of lithium-containing alumosilicate suspensions xLi₂O-Al₂O₃-nSiO₂-mH₂O in the system are presented for the first time. As a result of optimization, the optimal area of influence of variable factors was determined for the ratio of oxides Li₂O/Al₂O₃ from 0.82 to 1.05 mol, SiO₂/Al₂O₃ from 3.4 to 4.5 mol and H₂O/Al₂O₃ from 19 to 21.5 mol, providing normative levels of properties of lithium-containing alumosilicate suspensions, namely: density from 1.4 to 1.521 g/cm³, process viscosity from 15 to 47 sec, pH from 11.15 to 11.34, surface tension from 51.4 to 60.4 mN/m, cosine of the substrate contact angle from 0, 57 to 0.91, work of adhesion forces from 97 to 116 mN/m, work of cohesion forces from 103 to 121 mN/m, work of wetting forces from 27 to 52 mN/m, wetting coefficient from 0.78 to 0.96, spreading coefficient from –5 to –20 mN/m. The data obtained will form the basis for the creation of protective materials of new generation that, in the event of emergencies, can provide both the protection of people and technological equipment, buildings and constructions.
