High purity Silica, also known as Silicon dioxide, is one of the most subtle yet prominent materials in the world. It is the main filler in a lot of products, including semiconductor molding compounds, optical fibers, coating powder but also in building materials, solar panels and high performance ceramics. The list doesn't stop here. Adhesives, cosmetics, printing inks, epoxy mold compounds; all of them use Silica in varying purities and in huge quantities. The reliability requirements of these applications have raised the need for innovative extraction processes that remove impurities and contaminants and result in quartz with SiO2 content up to 99.99%.

Different applications require different silica formulations and can accept ranging purity tolerances, always in the range of 99+%. This varying need lead us to create and promote a large portfolio of Silica sub-products such as Quartz sand, Crystalline Micro Quartz powders and Spherical / Angular Micro Quartz powders. All of them compatible with the IOTA standards and with the ability to adjust Particle density based on the customer requirements.
Within our developmental projects, we are also conducting trials to commence production of high purity low alpha spherical silica micro powders to supply the premium end of the spherical silica markets.
When you think of glass, what comes to mind? Perhaps it's the windows in your home, the screen on your smartphone, or the glasses on your face. All these products have one key ingredient in common - silica sand. This seemingly ordinary material plays a crucial role in the manufacturing of glass, offering a range of benefits that are essential to the process.
Silica sand is incredibly pure. It's composed of finely ground quartz crystals, which are renowned for their purity. This is critical in glass manufacturing, as any impurities can affect the clarity and color of the final product. With silica sand, manufacturers can achieve the high-quality, transparent glass that consumers expect.

Another major advantage of silica sand is its excellent heat resistance. Glass manufacturing involves heating the raw materials to a very high temperature (over 1700°C). Silica sand can withstand these extreme conditions without melting, ensuring the integrity of the glass.
Silica sand is also extremely hard and durable, properties that are transferred to the glass it helps create. This is why glass products are able to resist wear and tear, lasting for years or even decades without losing their clarity or strength. Whether it's a window exposed to the elements or a smartphone screen subjected to daily use, the durability of glass is largely thanks to silica sand.
A final benefit of silica sand is its widespread availability. It's one of the most abundant materials on Earth, making it a cost-effective choice for glass manufacturers. This availability also ensures a stable supply, minimizing the risk of production delays due to material shortages.
While the mining and processing of silica sand do have some environmental impact, efforts are being made to reduce this. For example, water used in the washing process can be recycled, and waste materials can be used in other industries. Plus, glass products themselves are 100% recyclable, adding to the sustainability of the glass manufacturing process.
In conclusion, silica sand is an invaluable component in the glass manufacturing process. Its purity, heat resistance, hardness, and availability all contribute to the production of high-quality, durable glass products. So next time you look through a window or at your phone screen, remember the humble silica sand that made it all possible.
