IRAQI JOURNAL OF APPLIED PHYSICS Vol. 21, No. 3, July-September 2025, pp. 426-430 Sohaib S. Ahmed Highly-Pure Silicon Nitride Rand B. Lutfi Hayder G. Fahad Nanomaterial Prepared by Chemical Oday A. Hammadi Nitridation Method In this work, highly-pure silicon nitride nanopowders were prepared by chemical nitridation method. The tetraethyl orthosilicate (TEOS) was used as a precursor for silicon alkoxide while ammonia was used as a precursor for nitrogen. The structural characteristics of the prepared nanopowders were determined and studied as functions of annealing temperature carried out Department of Physics, during the preparation method. The chemical method used in this work can be characterized College of Education, by low cost, simple requirements, and reliability to produce highly-pure nanopowders. Results Al-Iraqia University, showed that the prepared nanopowders largely maintain an amorphous or highly Baghdad, IRAQ nanocrystalline structure, even at 1100 °C. Significant crystal
