Sodium Metasilicate

Description

Properties of Sodium Metasilicate:

Sodium metasilicate is an alkaline compound composed of sodium oxide (Na2O) and silica (SiO2). It exists in different forms, including anhydrous and hydrated variants. The anhydrous form appears as a white, crystalline powder, while the hydrated form exists as a colorless or white crystalline solid. Some key properties of sodium metasilicate include:

1. Solubility: It is highly soluble in water, forming an alkaline solution.
2. pH: The aqueous solution of sodium metasilicate is highly alkaline, with a pH value around 12-13.
3. Heat Stability: It exhibits excellent heat resistance, making it suitable for applications requiring high-temperature conditions.
4. Hygroscopicity: Sodium metasilicate is hygroscopic, meaning it readily absorbs moisture from the surrounding environment.
