Quartz fiber filters are manufactured from pure quartz fibers, preventing any surface filter reaction with acidic gases. Due to their inertness, quartz fiber filters are well suited for measuring heavy metal concentrations and small particle quantities. Quartz fiber filters also exhibit good weight and form stability.
QuartzCom, Oscillators, Crystals and Filters. Quartz is the second most abundant mineral in the Earths continental crust, after feldspar. It is made up of a continuous framework of SiO 4 silicon-oxygen tetraheda, with each oxygen being shared between two tetrahedra, giving an overall formula SiO 2.There are many different varieties of quartz, several of which are semi-precious gemstones.
