Filter Media, Glass Raw Material, Foundry Sand for Casting
Quartz sand, primarily composed of silicon dioxide (SiO₂), is a granular material processed from natural quartz rock through crushing, screening, washing, and other techniques. This product is graded based on SiO₂ purity, particle size distribution, and impurity content, typically appearing as white or colorless granules.
Valued for its high hardness (Mohs hardness 7), strong chemical stability, high-temperature resistance, high purity (SiO₂ content can exceed 99.9%), controllable particle size, and excellent filtration properties, quartz sand serves as a fundamental industrial raw material and holds a central position in pillar industries of the national economy, including water treatment, glass manufacturing, foundry, building materials, electronics, and photovoltaics.
Core Applications
Water Treatment and Filtration Industry
Multi-Layer Filtration Media: Quartz sand is the most widely used mechanical filtration media. In potable water treatment, industrial circulating water treatment, advanced wastewater treatment, and swimming pool filtration systems, utilizing quartz sand of different sizes to form multi-layer filter beds effectively traps and removes suspended solids, colloids, silt, algae, and some organic matter from water, ensuring effluent turbidity meets standards.
Support Layer for Ion Exchange: Used as the lower support bed in softener and demineralizer vessels containing ion-exchange resins to prevent resin loss.
Glass and Building Materials Industry
Primary Component in Glass Manufacturing: High-purity quartz sand is the principal raw material for producing flat glass, float glass, container glass, optical glass, and specialty glass. Its SiO₂ content and levels of impurities like iron and aluminum directly determine the glass's transparency, strength, color, and chemical stability. It typically constitutes over 70% of the total weight of a glass batch.
Building Materials: Used in producing Portland cement, refractory materials, ceramic glazes, engineered quartz stone, and epoxy flooring compounds as a filler, providing skeletal strength and wear resistance.
Foundry and Metallurgy Industry
Foundry Molding Sand: In metal casting (especially precision casting), high-purity quartz sand mixed with binders is used to create molds and cores that define the cavity of cast parts. Its properties of high-temperature resistance, low thermal expansion, and chemical inertness ensure dimensional accuracy and surface finish of castings, preventing reactions between molten metal and the sand mold.
High-Tech and Emerging Industries
Semiconductor and Photovoltaic Industry: Ultra-high-purity quartz sand (SiO₂ > 99.998%) is the raw material for manufacturing key consumables such as semiconductor silicon ingots, quartz crucibles (for pulling monocrystalline silicon), quartz tubes, and quartz boats. These materials critically impact the purity and performance of chips and solar cells.
Electronic-Grade Silica Fume/Microsilica: After ultra-fine grinding and purification, used as filler in integrated circuit packaging materials and Epoxy Molding Compounds (EMC).
Other Applications: Used in applications like abrasives (sandblasting, grinding), ceramics, and fillers.
