Physical and chemical properties

  • Purity: Up to 90% to 99% SiO₂ content ensures high purity of the quartz sand.

  • Impurity Content: Impurities such as Fe₂O₃ are low, generally not exceeding 0.06% to 0.02%, which is beneficial for enhancing the product's application performance.

  • Fusibility: Up to 1750°C, indicating that the quartz sand has excellent high-temperature resistance.

  • Appearance: Some large granules may have yellow skin sacs on the surface, but the overall appearance is neat.

Key Features

  • No Impurities: Processed through multiple stages to ensure low impurity content in the quartz sand.

  • Edgeless: The granules have a more regular shape with no sharp edges, which is beneficial for enhancing the product's performance.

  • High density: Possesses a high density, making the quartz sand more stable and reliable in applications.

  • High mechanical strength: Capable of withstanding significant mechanical stress, suitable for various strength-demanding scenarios.

  • High adsorption capacity: Capable of effectively adsorbing and carrying pollutants, ideal for water treatment and other fields.

  • Long service life: Thanks to its excellent physical and chemical properties, quartz sand boasts a longer service life during use.

Application Fields

Common quartz sand is widely used in various industries such as glassmaking, foundry, ceramics, refractory materials, metallurgy, construction, chemical engineering, plastics, rubber, and abrasives. For instance, in the glass industry, quartz sand is a key raw material for producing flat glass and float glass products; in the foundry industry, it is used as molding sand to shape castings; and in the water treatment industry, quartz sand serves as a filter material to remove suspended particles and impurities from water.
