Abstract: The Gibbs free energy and critical reduction temperature of vacuum silicothermic reduction producing metallic strontium were calculated and analyzed by thermodynamics.
For example, there was the leaking of highly radioactive water in 2016, and strontium and other radioactive substances were found to have exceeded normal standard in 2018.
Strontium aluminate is more expensive, but it has a longer persistence, which means it emits visible light more slowly, and glows longer after being energized.
