What Are Quartz Sand Specifications for Buyers?

Quartz sand is a highly versatile material used in various industries, including construction, glass manufacturing, and filtration. Understanding the specifications of quartz sand is crucial for buyers looking to make informed purchasing decisions. Here’s a structured guide to essential quartz sand specifications:

1. Purity Level
   • Quartz sand typically has a purity level of over 90% Silicon Dioxide (SiO2).
   • High-purity sands (over 98% SiO2) are preferred for glass and solar panel manufacturing.
2. Grain Size Distribution
   • Grain size affects the performance of quartz sand in various applications.
   • Common size ranges include fine (0.063mm to 0.25mm), medium (0.25mm to 1mm), and coarse (1mm to 4mm).
   • Glass manufacturing typically requires finer grains.
3. Shape and Angularity
   • Grain shape can influence the packing density and strength of materials.
   • Rounded grains are often preferred for applications like concrete, while angular grains are suitable for filtration and more structural purposes.
4. Color
   • Color indicates the presence of impurities; pure quartz sand is usually white to clear.
   • Colored sands may also be desired for aesthetic purposes in landscaping and construction.
5. Moisture Content
   • Moisture content should be as low as possible, ideally below 5%, to ensure quality and performance.
   • Excess moisture can affect the weight and integrity of the material.
6. Packaging and Transportation
   • Quartz sand is commonly packaged in bulk bags or in sacks ranging from 25kg to 1 ton.
   • Consider the logistics of delivery and storage when selecting suppliers.
7. Provide Certifications
   • Verify if the quartz sand supplier has appropriate certifications, such as ISO or ASTM, to ensure compliance with industry standards.
   • Certifications often reflect the quality and reliability of the product.

In conclusion, when searching for quartz sand, it's crucial to consider these specifications that significantly impact its application and effectiveness. By understanding these factors, buyers can ensure they are investing in the right kind of quartz sand for their specific needs.
