Heraeus Conamic | Making of fused quartz and fused silica
Flame Fusion. Historically, the first method of producing fused quartz was by small-scale fusion of quartz crystals in a flame. Heraeus chemist Richard Küch first began fusing quartz rock crystal in a hydrogen/oxygen (H2/O2) flame more than 100 years ago. Heraeus has been producing quartz glass on an industrial scale with this process ever ...

The role of microorganisms in gold processing and recovery—A review
Quartz comprises 20% of the volume of the exposed Earth's crust and is one of the most resistant of rock forming minerals (Brehm et al., 2005, White and Brantley, 1995). Its rate of dissolution is slow, approximately 10 − 17 mol cm − 1 s − 1 at 40 °C at near neutral pH in pure water, because the activity required to break Si–O bonds is ...
