What is Silica Sand
Silica sand is a versatile material that’s utilized by several industries. If you’re not sure what it is, though, we’re here to help. Learn all about silica sand, what it is, and how it’s used professionally, plus where you can buy some yourself.
Properties of Silica Sand
Silica sand, also known as quartz sand, is primarily made up of silicon dioxide (SiO2). The name ‘silica’ originates from the Latin word ‘silex’, which means flint or hard stone.
Not all silica is round, which is crucial for customers who want to know the roundness of our material. While the particles of silica sand are often described as round due to weathering and the action of wind and water over time, Holliston Sand’s source has been measured as “sub-rounded” and “sub-angular.” The uniform, spherical shape of the particles, along with their hard crystalline structure, is what gives silica sand its distinctive properties.
Physical and Chemical Properties
Silica sand possesses several physical and chemical properties that make it stand out among other types of sand. Being chemically inert, stable, and non-toxic contributes to its resistance against chemical weathering and corrosion, making it safe for numerous applications. Physically, silica sand is hard and resistant to wear and tear, making it quite durable. It also has a high melting point—around 1713°C.
Silica sand is known for its high thermal conductivity, an attribute that benefits industries such as foundry work. It also has a relatively high degree of refractivity, which makes it ideal for glass manufacturing.
What Is Silica Sand Used For?
One of the most popular applications of silica sand is in sports and recreation. It’s commonly used on golf courses and sports fields because it improves aeration, drainage, and durability. The roundness and texture of the sand particles make it an ideal material for topdressing greens, tees, and fairways.
In water filtration systems, silica sand acts as a natural filter to remove impurities. The sand traps particles, including dirt, dust, leaves, and even microorganisms, allowing clean water to flow through. The effectiveness of silica sand in water filtration has resulted in its widespread use in municipal water treatment plants, pools, aquariums, and even in-home filtration systems.
Other Applications of Silica Sand
The majority of all silica sand produced is used in the glass industry. Its high-temperature resistance, transparency, and ability to fuse easily make it an excellent base material for producing a wide range of glass products, from windows and bottles to fiberglass and specialty glass.
Silica sand is commonly used in foundry casting processes to create molds for metal casting. Its high melting point and thermal conductivity are ideal properties for handling the high temperatures associated with metal casting.
In the ceramics industry, silica sand is used to provide strength and durability to ceramic products like tableware, tile, and porcelain. Similarly, it’s used in the creation of refractory materials due to its high heat resistance.
