Structure and Thermal Behaviour of Lithium Sodium Sulphate

Lithium sodium sulphate (LNS) has been synthesised by two methods: mechanical ball milling and melt quenching. The obtained materials have been studied by means of X-ray diffraction, scanning electron microscopy (SEM), Infrared spectroscopy and differential scanning calorimetry. The influence of the synthesis method on the structure and behaviour of the materials will be discussed.
