Metallic rhenium, with its melting point of 3180°C, stands as the last naturally occurring stable element to be discovered and an irreplaceable strategic material for cutting-edge fields such as aerospace and nuclear energy. I. The Metal King Breaking Through High-Temperature…
AbstractThe purity of gallium directly determines its suitability for high-end technological applications and the resulting device performance. Gallium products are categorized by purity into metallic gallium (4N and below) and high-purity gallium (5N to 8N). The purity progression from 99.99%…
AbstractHafnium, with its exceptionally high melting point of 2233°C, excellent high-temperature mechanical strength, and oxidation/ablation resistance, has become a critical strategic material for extreme high-temperature environments today. Its high-temperature performance is realized through three forms: as a grain boundary strengthening…
AbstractOsmium, as one of the rarest elements in the Earth’s crust, represents the precious metal with the lowest global production and consumption, with an annual output of approximately 2 tonnes. Its supply exhibits a highly concentrated bipolar pattern, with South…
AbstractIridium and its alloys represent the pinnacle of materials for confronting extreme environment challenges, primarily deployed in cutting-edge fields with near-absolute demands for high-temperature resistance, corrosion resistance, and stability. This stems from iridium’s unparalleled combination of properties: it possesses one…
