Product type
Silica sand is a naturally occurring granular material composed primarily of silicon dioxide (SiO2). It is formed through the weathering and erosion of rocks, resulting in fine particles that are used in a variety of industrial applications. Silica sand is known for its high purity and is typically processed to remove impurities, making it suitable for various uses in industries such as construction, glass manufacturing, and ceramics.
| Chemical composition | Minimum 95% silicon dioxide |
| Grain size | Typically ranges from 0.1 mm to 2 mm |
| Color | Usually white or tan, depending on impurities |
| Moisture content | Typically less than 0.5% |
| Bulk density | 1.5 to 1.8 g/cm³ |
When selecting silica sand, buyers should consider the specific application requirements, including grain size, purity levels, and moisture content. It is also important to specify any necessary certifications or industry standards that the silica sand must meet, depending on its intended use. Additionally, buyers should determine the quantity required for their projects to ensure proper supply.
