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. 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.

YASMAh is a leading supplier of Silica Quartz Ore with an impressive purity level of 99.5% SiO2 and exceptional thermal stability, catering specifically to the alloy industries. With a robust supply capacity of 200,000 metric tons per annum, we are committed to meeting the high demands of alloy manufacturers with top-quality silica quartz ore.
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 Granular ( Supreem Grade )
Geological processes have occasionally deposited sands composed of nearly 100% quartz grains. These deposits are identified and produced as sources of high-purity silica sand, which is essential for the glassmaking industry. Quartz sand is utilized in the production of container glass, flat plate glass, specialty glass, and fiberglass. High-purity quartz sandstone, known as quartz glass sand, is ideal for manufacturing high-quality glass. "Glass sand" refers to sandstone almost entirely made of quartz grains. Pictured is a specimen of the Oriskany Sandstone from Hancock, West Virginia. In some locations, the Oriskany is over 99% pure quartz. While much of it is used for container glass, some is selected for making lenses for the largest telescopes. The specimen measures about four inches (ten centimeters) across.
