Effects of modulus of sodium silicate solution on mechanical properties and microstructure of geopolymer [PDF]
, 2011 Four sodium silicate solutions of modulus m = 1.0, 1.2, 1.4 and 1.6 were prepared as activators used in metakaolin-based geopolymer synthesis. The effects of modulus of activator on the mechanical properties and microstructure of the geopolymers were ...

Viscosities of melts in the Na2O---FeO---Fe2O3---SiO2 system and factors controlling relative viscosities of fully polymerized silicate melts [PDF]
, 1988 Na2O---B2O3---SiO2 and Na2O-Ga2O3 viscosities decrease in the order aluminosilicate > ferrosilicate, (galliosilicate ?) > borosilicate. Thp electronegativities of the trivalent cations are inversely correlated with the relative viscosities of melts in ...

Viscosity-temperature relationships in the system Na2Si2O5-Na4Al2O5 [PDF]
, 1986 The viscosity-temperature relationships of five melts on the join Na2Si2O2-Na4Al2O5 (5, 10, 20, 30 and 40 mole percent Na4Al2O5) have been measured in air, at 1 atm and 1000–1350°C with a concentric cylinder viscometer.

JAMA: The Journal of the American Medical Association, 1884 Gentlemen:—I have frequently conversed with physicians of ability, age and experience, who have never employed and consequently never appreciated the value of silicate of sodium bandage as a permanent dressing in fractures of the long-bones. Silicate of sodium is a solution of silica and sodium carbonate, containing 20 parts of the former to 10 parts ...

Advanced Functional Materials, EarlyView.Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...
