Will metal scarcity impede routine industrial use

摘要: Materials scientists today employ essentially the entire periodic table in creating modern technology. In an age of sharply increasing usage, it is reasonable to wonder about supplies these elemental building blocks. this article, we review current and prospective supply demand for a variety metals. Although data are often sparse, available information suggests that practices likely lead scarcity some metals not-too-distant future. We conclude by discussing policies that, if adopted, might defuse concerns.
