RE:HPQ SILICA TO HIGH PURITY SILICON PRODUCTION PROCESS Very interesting indeed. HPQ Silicon's President, Bernard Tourillon, has often highlighted that with HPQ's Quartz Reduction Reactor (QRR), the benefit is that HPQ can use lower purity silica/quartz in the process of production Silicon. And this is what HPQ does with the QRR.
Long and Strong in HPQ Silicon and PyroGenesis!
