What is 20 Silica Sand?

Silica sand, chemically known as silicon dioxide (SiO2), is a granular material derived from the erosion of rocks rich in quartz. The ’20’ in 20 silica sand refers to its mesh size, indicating that it will pass through a sieve with 20 openings per linear inch. This classification places it in the coarser range of industrial sands. Its properties, including hardness (7 on the Mohs scale), chemical inertness, and high melting point, make it highly valuable across various sectors. The consistent quality and specific grading are crucial for its performance in applications such as glass manufacturing, foundry molds, construction, and water filtration. When considering options for 20 silica sand Lowe’s might carry, it’s important to differentiate between general-purpose sand and specific industrial grades.

Purity and Composition

High-quality silica sand typically contains over 95% SiO2, though many industrial applications, such as clear glass production, require purities exceeding 99%. Impurities like iron oxides, alumina, and calcium carbonate can affect the sand’s color, melting point, and reactivity. For instance, iron impurities can impart an undesirable color to glass. Understanding the purity level is paramount, especially when comparing products available at retail outlets versus those from specialized industrial suppliers. Sourcing from reputable providers ensures that the sand meets the necessary chemical specifications for its intended use.

Particle Size and Shape

The 20 mesh classification signifies a coarser grain size compared to finer sands used in applications like sandblasting for delicate surfaces. The particle size distribution and shape (rounded vs. angular) influence its flow properties, packing density, and performance in filtration or as an aggregate. For applications like concrete or mortar, the particle shape can impact the strength and workability of the mix. While retail options may offer general-purpose sand, industrial users often need precisely graded sand to ensure consistent results in their manufacturing processes.
