Silica Sand Product Description and Applications



WCR’s High-grade silica possesses a high level of purity and quality. The test results from Nagrom Analytical Services Perth have identified that the product from the WCR operation is 99.751% silica.  The silica contains a minimal number of impurities.  We know that the level of purity is a crucial factor in determining the suitability of silica for various industrial applications. Here are some key characteristics and applications of high-grade silica:

  1. Purity: High-grade silica is characterized by its high purity, often with silica content well above 95% and sometimes even exceeding 99%, WCR’s product is 99.751%. The low presence of impurities makes it suitable for applications where purity is critical.
  2. Hardness: Quartz, the primary component of silica sand, is a hard mineral. This hardness contributes to the abrasive properties of silica sand, making it useful in applications such as sandblasting and water filtration.
  3. Chemical Inertness: Silica sand is chemically inert, meaning it does not react with most substances. This property makes it ideal for use in various chemical processes and applications.
  4. High Melting Point: Silica sand has a high melting point, which makes it useful in the manufacturing of glass, ceramics, and other refractory materials.

Common applications of silica sand include:

  1. Glass Manufacturing: High-grade silica is commonly used in the glass industry to produce clear and high-quality glass products. The purity of silica is essential to ensure the transparency and other desired properties of the glass.
  2. Electronics and Semiconductors: In the electronics industry, high-purity silica is used in the production of semiconductors, photovoltaic cells, and other electronic components. The low impurity levels are crucial to prevent contamination during the manufacturing process.
  3. Solar Panels: High-grade silica is utilized in the manufacturing of solar panels, where purity is essential for the efficient conversion of sunlight into electricity.
  4. Precision Casting: In industries like precision casting, high-grade silica is used to produce moulds for the casting of metals. The purity ensures a clean and precise casting process.
  5. High-Tech Applications: Silicon wafers to produce integrated circuits and other high-tech applications require high-purity silica. The semiconductor industry relies on such silica for its exceptional electronic properties.
  6. Pharmaceuticals and Cosmetics: High-grade silica is used in pharmaceuticals and cosmetics as a component in various products, including pharmaceutical tablets, personal care products, and cosmetics.
  7. Construction: Silica sand is used in the production of concrete and mortar. It can also be used as a bedding material for paving.
  8. Industrial Abrasives: Due to its hardness, silica sand is used as an abrasive in processes like sandblasting, where it is used to clean or etch surfaces.
  9. Water Filtration: Silica sand is commonly used in water filtration systems to remove impurities and particles from water.
  10. Oil and Gas Industry: Silica sand is used in hydraulic fracturing (fracking) to prop open fractures in the rock and allow oil and gas to flow more freely.
