Silica Sand 20: A Comprehensive Overview
Are you curious about silica sand 20? This article delves into the details of this versatile material, exploring its properties, applications, and the factors that make it stand out in the market. Whether you’re a manufacturer, engineer, or simply interested in the world of industrial materials, this guide will provide you with a comprehensive understanding of silica sand 20.
What is Silica Sand 20?
Silica sand 20, also known as 20 mesh silica sand, is a fine-grained, natural quartz sand that has been processed to remove impurities. It is characterized by its high purity, which is typically above 99.5%. The “20 mesh” refers to the particle size distribution, meaning that the sand consists of particles that pass through a 20-mesh screen but are retained on a 40-mesh screen.
Properties of Silica Sand 20
Here are some key properties of silica sand 20:
| Property | Description |
|---|---|
| Purity | Typically above 99.5% |
| Particle Size | 20 mesh (0.875 to 0.150 mm) |
| Hardness | 7 on the Mohs scale |
| Specific Gravity | 2.65 |
| Chemical Composition | SiO2 (Silicon Dioxide) – 99.5% or higher |
These properties make silica sand 20 an ideal material for various applications, as it offers excellent thermal conductivity, resistance to chemicals, and a high melting point.
