In glass chemistry, it is important to study the structural changes during glass transition and phase transition. Solid State Nuclear Magnetic Resonance (SSNMR) is a good tool to study the glass structure by employing in-situ MAS NMR spectroscopy. This study deals with structure network of Alkali-phosphate and its evolution upon heating and annealing using in-situ MAS NMR spectroscopy. The temperature used for MAS NMR is around and above glass transition temperature to evaluate the structure evolution upon heating. The results from in-situ MAS NMR techniques have also been discussed, wiz. Doty HT-MAS, LASER and Inductive heating at temperature above 650 oC with higher
