The Sodium Tetraborate Anhydrous by Dinâmica, available at LojaLab, is an alkali borate with no water of crystallization, represented by Na2B4O7. It is used as a borate source in solution preparation, acid-base equilibrium studies and laboratory processes specifying the anhydrous form. Its molar mass is substantially lower than that of borax decahydrate, so any substitution requires recalculation.
Characteristics
- Anhydrous sodium tetraborate, distinct from borax decahydrate
- White, odorless solid as completely soluble
- Melting point of 741 °C
Applications
- Preparation of borate solutions and media calculated from anhydrous Na2B4O7
- Studies of acid-base equilibrium, buffer capacity and borate complexation
- Use as a flux or fusion-mixture component when the method specifies sodium tetraborate
- Laboratory-scale tests involving glass, ceramics, glazes and inorganic materials.
