Exploration of new materials and processing using sodium

Research output: Contribution to journalArticlepeer-review

Abstract

Recent studies on the preparation of some Si containing materials and Si crystals by using Na were reviewed. Silicon carbide and beta-iron disilicide (β-FeSi2) were fabricated at 700-800°C with Na melt or Na vapor. A new compound, Ba3Si4C2, was synthesized with Na melt and SiC nano-powder. The phase diagram of Na-Si binary system was proposed based on the results of thermal analysis and observation of sample morphology. Polycrystals and single crystals of Si were obtained by evaporation of Na from Na-Si melt at 800-900°C.
