The thermal stability of polycrystalline tin selenide (SnSe) is essential for its long-term applications. In this study. the thermo-mechanical stability of hot compacted polycrystalline SnSe and SnSe/graphene nanocomposite is evaluated. All samples were prepared using a combination of mechanical alloying and hot compaction under an argon atmosphere. https://www.parisnaturalfoodes.shop/product-category/deep-ocean-minerals/
