Non Silica Sands

Non-silica sands are natural or synthetic granular materials that do not contain silica. They are used for a variety of industrial and commercial applications, including foundry casting, metal production, construction, water filtration, and landscaping. These sands have unique properties and characteristics that make them suitable for specific purposes, and they come in a range of colors, shapes, and sizes.

One of the main advantages of non-silica sands is that they are generally safer for workers and the environment than silica sands, which can cause respiratory problems and other health issues if inhaled. Non-silica sands do not generate dust or particulate matter that can be harmful to people or wildlife, and they are often made from sustainable or recycled materials.

Some common types of non-silica sands include:

- Olivine sand: This green sand is made from magnesium iron silicate and is primarily used in foundry casting for its high melting point, low thermal expansion, and good casting quality.

- Garnet sand: This reddish-brown sand is made from the mineral garnet and is used in abrasive blasting, waterjet cutting, and filtration for its hardness, durability, and low dust generation.

- Zircon sand: This white sand is made from the mineral zircon and is used in foundry casting, ceramics, refractories, and nuclear power for its high melting point, low thermal expansion, and radiation resistance.

- Calcium carbonate sand: This white sand is made from limestone and is used in construction, agriculture, and water treatment for its low abrasiveness, pH-neutralizing properties, and calcium content.

- Glass beads: These transparent or colored beads are made from recycled glass and are used in abrasive blasting, metal finishing, and reflective road markings for their smoothness, hardness, and reflective properties.

Non-silica sands can also be customized and blended to meet specific requirements for color, texture, size distribution, and chemical composition. Some sands can even be treated or coated with additives to improve their performance or functionality in specific applications.

Overall, non-silica sands offer a safe, sustainable, and versatile alternative to silica sands for many industrial and commercial applications. As technology and innovation continue to advance, new types of non-silica sands may emerge that offer even better properties and benefits for various industries and markets.
