The Inside Story of the Great Silicon Heist

But metallurgical-grade silicon is far too tainted with flecks of iron, aluminum, and calcium to be usable in high tech products that are expected to perform flawlessly for years on end The material must thus be chemically refined, a process that begins by mixing it with hydrogen chloride at more than 570 degrees Fahrenheit.
