High-purity quartz sand is classified based on size and grade. Its several types serve distinct industrial purposes.
This type of sand is sorted into various grades like 99.5% or 99.9% purity, depending on the required particle size distribution. It is widely applied in semiconductor and solar panel manufacturing because even tiny pollutant traces can affect productivity.
Fumed silica is manufactured through the flame-oxidation of silicon tetrachloride. This process produces very fine silica particles. The resultant product has high purity, lightness, and exceptional viscosity. These qualities make it a key candidate in the pharmaceutical and cosmetic industries.
This high-purity powder is acquired by grinding quartz crystals. After grinding, they sieve the result to attain the desired particle size. Commonly, this sand has purity levels ranging from 99.5% to 99.9%. This powder is an essential raw material in diverse industries, from glass to electronics and even in construction.
Precipitated silica is manufactured by neutralizing sodium silicate with an acid to precipitate silicon dioxide. The silicon dioxide is then purified and dried to produce silica with a consistently fine texture and high purity. It is mainly used in rubber manufacturing, offering reinforcement and extending longevity.
Colloidal silica is produced by dispersing purified silica in water or an appropriate liquid medium. This method produces a stable silica suspension with high purity. It is used in the glass industry and as a binder in foundry sands. Its viscosity and stability enable control when coating or molding.
The high-purity quartz sand application extends widely and is highly valued in different industries like semiconductor, photovoltaic, and glassmaking.
High-purity quartz sand is crucial to the semiconductor industry's need for silica. Quartz sand is converted to molten silicon through a chemical reaction between carbon and SiO₂ at 2000°C. The silicon produced is extremely pure and used to manufacture silicon wafers. These have a vital role in microchips and integrated circuits, which are the building blocks of contemporary electronics.
High-purity quartz sand is a vital silicon component used in solar cell production. The silicon is produced by a chemical reaction between quartz sand and carbon in a furnace at 2000°C. This resultant silicon is used to manufacture photovoltaic cells, which convert sunlight into electrical energy. This sand's demand in this space directly correlates to the rise in renewable energy quest.
High-purity quartz sand is especially applied in specialty and optical glass manufacturing. The silicon dioxide's impurity levels in this sand guarantee that the resultant glass has no flaws or discoloration. Optical glass, which transmits light with minimal loss, is essential for precision instruments, cameras, and fiber optics.
This sand comes in handy in producing abrasives like sandblasting grains and grinding wheels. Its high purity ensures consistency and effectiveness when used in surface finishing applications. Also, it is used in making refractory materials. These are used in high-temperature industrial settings like furnaces and kilns. Its ability to withstand extreme heat keeps equipment secure and boosts operational effectiveness.
The high-purity quartz sand key features include high silicon dioxide content, low metallic impurity concentration, and consistent particle size. These characteristics make it ideal for various demanding applications. Its high silicon dioxide content makes this sand a superb silicon source in tech industries. A low impurity concentration prevents unwanted reactions in chemical and high-tech processes. Finally, the consistent particle size enhances material uniformity. This improves efficiency and efficacy across applications.
Silicon Dioxide Content
The silicon dioxide concentration in quartz sand determines its usability. In sandbox, the SiO₂ content is 99.5% to 99.9%. This high concentration gives it extraordinary purity, making it a premier choice for industries requiring high silica content.
Grain Size Distribution
The particle size of this sand is quite consistent. The consistency leads to an even surface and uniform material flow in industrial applications. Often, manufacturers give the required grain size to the buyer based on the application's needs.
Filtration and Washing
This sand is washed using advanced techniques to eliminate organic and inorganic pollutants. Manufacturers run the filtration through several stages to ensure no particulate matter contaminates the quartz sand.
Packaging
Once filtered and dried, high-purity quartz sand is packaged in 25 kg bags or bigger containers. The choice of packaging can be influenced by the buyer's transport and storage prerequisites.
For buyers, when selecting high-purity quartz sand, they should consider the supplier's ability to ensure consistent purity levels. Moreover, sand grain size and distribution are critical. These factors influence the sand's industrial application efficacy. Therefore, they must verify these attributes and the sand's silicon dioxide content. Additionally, reputation and reviews are important. Then, they should assess the supplier's capacity to deliver on large-scale orders consistently. Also, a reliable supplier should be able to explain the sand's origin and processing techniques. Prioritizing sustainable partners aligns with global eco-friendly initiatives. Finally, transparent pricing with no hidden costs will streamline budgetary processes. Following this makes informed decisions when purchasing high-purity quartz sand.
A1: Yes, high-purity quartz sand is more pure than the normal sand. It contains more than 99.5% silicon dioxide. Meanwhile, normal sand contains less than this amount. Also, this sand undergoes rigorous purification. It is filtered and cleaned by fumed silica, which removes impurities like metals, organic matter, and dust. Normal sand lacks this process.
A2: Businesses that need silica for industrial use buy this sand in bulk. Companies that manufacture glass, chemicals, and abrasives. Also, foundries and construction firms use the sand. Quartz sand is critical for creating silicon wafers in the semiconductor industry. Thus, it is needed in electronic manufacturing. Also, high-purity quartz sand is key to solar cell production.
A3: Its price depends on various factors, including mining costs, processing expenses, packaging and shipping charges, and market demand. Usually, the processing methods used to purify and refine the sand determine the sand's final cost. For example, purification processes that involve chemicals or high energy expenditures will likely cost more than basic washing and screening.
A4: Often, there is a minimum order requirement. This amount varies based on the supplier's policy and the buyer's intended industry use. Suppliers like manufacturers often require large minimum orders, while wholesalers and resellers tend to have lower limits.
A5: The lead time varies based on factors like order size, sand availability, and the distance between the buyer and seller. Normally, logistics arrangements like the chosen transport mode influence the time. Orders with the shortest shipping time or overland transportation often take a week. However, bulk orders requiring processing and customization may take more.
