- •
β, δ, and α phases of layered sodium silicates are prepared from rice husk ash using a simple process.
- •
The phases transform from β to δ to α as time and temperature increase.
- •
Optimal synthesis conditions produced layered sodium silicates that exhibited excellent Ca2+ and Mg2+ binding capacities.
- •
Agricultural waste is converted to valuable products for potential use as detergent builders.
