Dec 27, 2019 This paper introduces in detail the high efficiency magnetic separation process of quartz sand and the series of equipment adopted. Due to the influence of environment, it is impossible to produce high-purity quartz sand by flotation, acid leaching and other methods in some areas, so it is necessary to use pure physical methods to reduce iron and purify quartz sand. The traditional method
AGI Multiple Nozzle Burner for MCVD method is made of quartz. The design of this burner produces a high efficiency flame and an accurate focal distance similar to AGI Quartz Burner for OVD and VAD methods. Each burner made by AGI is individually inspected and supplied with a 3D inspection report.
Quartzdyne pressure transducers rely on a vibrating or resonating quartz disk as the foundation of its sensing ability. Quartz is a perfectly elastic high Q material, meaning there is an insignificant loss in energy once it starts resonating. This characteristic provides excellent sensor stability, repeatability and requires minimal power.

Quartz lamps efficiently use the heat created in the infrared region. The heat source is also environmentally friendly and causes no pollution. Quick Heating Rates One reason for the efficiency of quartz heaters is the extremely fast heating caused by high thermal transfer. This results from the high source temperature of the tungsten filament.
