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
B grade quartz: Quartz lumps with one or more sides contaminated with iron oxidation marks, clay, etc.
