Sodium Silicate - an overview | ScienceDirect Topics

Both sodium silicate and silico fluoride solutions are applied to clean, dry, sound concrete floors as dilute aqueous solutions (10 to 15 per cent solids) in 2 to 3 applications, taking care to ensure that the solution penetrates and is absorbed into the concrete surface. The silicate or silico fluoride reacts with the small amount of free lime

Borosilicate glass - Wikipedia

Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 × 10 −6 K −1 at 20 °C), making them more resistant to thermal shock than any other common glass. Such glass is subjected to less thermal stress and can withstand temperature differentials
