B grade quartz: Quartz lumps with one or more sides contaminated with iron oxidation marks, clay, etc.
Quartz chips of M grade are similar to quartz lumps of M grade in terms of their high purity and particle size. They also have a minimum SiO2 content of 99.95% and are considered to be of medium grade, with a particle size ranging from 1mm to 6mm. Quartz chips are commonly used in the manufacturing of high-quality glass, ceramics, and electronics components. They are also used in the construction industry as an additive to concrete and mortar to increase strength and durability. The M grade quartz chips are preferred in applications where a medium particle size is required. They are often used as a filler material in the production of refractory products, such as high-temperature insulation and linings

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.
Quartz A grade refer to high-quality quartz that are of the highest grade and purity. This grade typically has a minimum SiO2 content of 99.60 - 99.99%, 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.
