Quartz A grade refer to high-quality quartz that are of the highest grade and purity. This grade typically has a SiO2 content of 99.9% and above, making them suitable for use in industries where high purity is critical, such as in the production of high-quality optical lenses, semiconductors, and other electronics components. Quartz A grade has a particle size ranging from 1mm to 10mm, in the case of Lumps, depending on the specific application. They are carefully selected and processed to ensure that they meet strict quality standards, including low levels of impurities and uniform particle size distribution.
High purity quartz powder is processed from the quality Quartz (or quartz) stone. It has a high purity of SiO2, a low impurity content, which is used as raw materials of optical glass, refractory, metallurgy,ceramic, foundry, abrasives etc.
Our Glassy Quartz lumps is currently the one of only known high purity lump quartz available in large, chemically consistent quantities and is suitable for a wide range of high-tech applications, including the manufacture of High Purity Quartz Sand Manufacturing,Lighting,Optical Fibre,Solar crucibles, quartzware and tubing.
