Sodium aluminate, NaAlO2• xH2O, is an important comercial chemical used in water treatment, as a source of aluminium in the preparation of zeolites and other catalytic materials and as an additive in paper manufacturing. Sodium aluminates were synthesised in this work by using the Al(NO3)3 •
9H2O- NaOH system’s controlled precipitation method.
Using the controlled precipitation method enabled identifying
the process’s different stages from potentiometric titration of
Al(NO3)3 • 9H2O dissolved in water and using NaOH as
precipitating agent to ensure control and reproducibility and
also identify final product characteristics. Powders were characterised by infrared spectroscopy (FTIR), X-ray diffraction
(XRD) and gravimetric and differential thermal analysis
(GDTA). The results indicated that NaAlO2 crystallised well at
1000°C (obtained as the main crystalline sodium aluminate
phase) and that β-alumina treatment began to form at
1500°C.
