Exceptionally high purity, with SiO₂ (silica) content typically between 99.7% and 99.9%.
Bright white color and glassy appearance, minimal impurities, and superior whiteness (often 97%+).
Carefully selected and processed to meet stringent standards for uses in Semiconductors, glass manufacturing, ceramics, foundry, and high-end industrial applications.
Fe₂O₃ content is very low (around 0.01% or below).
Sizing: Usually available in 30 mm to 100 mm or as required by the client. These are the lumps of snow-white quartz that we offer in various sizes to our customers. For best-in-class quartz lumps, we have some of the most cutting-edge equipment and storage facilities.
In a variety of industries, including the glass and ceramics industries, they are widely used.

Medium quality with slightly lower SiO₂ content (typically around 97.5%–98%). White or off-white appearance; may have minor visible impurities compared to A Grade.
Used for ceramic, ramming mass, and certain foundry applications where ultra-high purity is not required.
Fe₂O₃ and Al₂O₃ contents are generally higher than in A Grade.
Sizing: Commonly ranges from 25 mm to 150 mm depending on industrial need.
Best For: Cost-effective industrial and ceramic uses not requiring the highest purity.
