dioxide. Silicone is widely used in various fields such as adsorbents,
desiccants, catalysts, etc; Silicon dioxide is widely used in industries such as
coatings, adhesives, and rubber.
Application case: In industries such as chemical, pharmaceutical, food
processing, and oil and gas extraction, silica and silica gel produced from
quartz sand are used for adsorption, filtration, drying, catalysis, and other
fields.
Key features:
High purity: After fine processing, quartz sand can obtain high-purity
silicon dioxide to meet the needs of various chemical reactions.
Multifunctionality: Silicon dioxide and silica gel are widely used as
adsorbents and catalysts in industries such as chemical engineering,
environmental protection, and energy.
5. Manufacturing of electronic chemicals
After high-purity treatment, quartz plate sand can be used to manufacture
electronic chemicals, such as optoelectronic materials, electronic device
packaging materials, etc. Due to its extremely high chemical purity and
stability, quartz sand has a wide range of applications in the electronics
industry.
Application case: Quartz sand is used as the basic raw material for
electronic grade materials in integrated circuit (IC) manufacturing, fiber optic

electronic grade, ensuring the quality of electronic products during the
manufacturing process.
Low impurity content: High purity quartz sand is crucial for the stability of
electronic chemicals, as it can avoid introducing impurities into electronic
products.
6. Production of Silane Compounds
Silane compounds are a type of chemical produced by the reaction of silicon
with hydrogen, chlorine, nitrogen, and other elements. They are widely used in
fields such as electronics, optoelectronics, solar energy, and coatings. Quartz
sand provides a silicon source for the synthesis of silane compounds.
Application case: Quartz sand is used as an important raw material for
synthesis reactions in the production of organic silicon materials, silane
crosslinking agents, silane coupling agents and other chemicals.
Key features:
High silicon content: Quartz sand is rich in silicon element, which serves as
a key raw material for the synthesis of silane compounds.
Chemical stability: Quartz sand is not easily decomposed during the reaction
process, which can ensure the stability and efficiency of the synthesis
process.
7. Environmentally friendly catalysts
Quartz sand is also used in the production of environmentally friendly
catalysts, especially in waste gas treatment, sewage purification, and
industrial waste recycling. Quartz sand has excellent performance as a carrier.
For example, quartz sand can be used as a carrier for activated carbon to help
remove harmful substances from exhaust gases.
Application case: Quartz sand is used as a catalyst carrier to reduce harmful
gas emissions in fields such as automobile exhaust treatment and factory exhaust
gas treatment.
Key features:
Excellent adsorption performance: Quartz sand can adsorb and fix pollutants,
improving the efficiency of catalysts.

corroded or damaged and can be used for a long time.
8. Manufacturing of oilfield chemicals
Quartz sand, as a high-temperature resistant and chemically stable material,
is widely used in the production of oilfield chemicals, especially in the
preparation process of hydraulic fracturing fluids. Quartz sand is used as a
supporting agent to help maintain open fractures and improve oil and gas
extraction efficiency.
