Products Description
Sodium metasilicate is a white granular inorganic compound that is readily soluble in water and dilute sodium hydroxide solutions, but insoluble in ethanol and acids. It is widely used as an analytical reagent, fabric flame retardant, adhesive, hardener, weighting agent, and filler, while also playing important roles in mineral flotation and petroleum refining processes.
