What is quartz sand?
Quartz sand is a kind of natural mineral sand with quartz as the main component. It is widely used in industry, construction, water treatment and other fields. In recent years, with the rapid development of environmental protection and material science, the popularity of quartz sand has increased again. This article will combine the hot topics and hot content on the Internet in the past 10 days to give you a detailed introduction to the definition, characteristics, uses and market data of quartz sand.
1. Definition and characteristics of quartz sand
Quartz sand is a granular material made from natural quartz stone through crushing, screening, washing and other processes. Its main component is silica (SiO₂), which has high hardness, stable chemical properties, and resistance to acid, alkali and high temperature. The following are the main properties of quartz sand:
| characteristic | describe |
|---|---|
| Element | Silica (SiO₂) content ≥90% |
| hardness | Mohs hardness 7, second only to diamond and corundum |
| melting point | About 1650℃ |
| color | White, light yellow or translucent |
| density | 2.65g/cm³ |
2. Uses of quartz sand
Quartz sand is widely used in many fields due to its unique physical and chemical properties. The following are the main uses of quartz sand that have been hotly discussed on the Internet in the past 10 days:
| Application areas | Specific use |
|---|---|
| construction industry | Concrete aggregate, floor materials, exterior wall decoration |
| water treatment | Filter material to remove suspended solids and impurities in water |
| glass manufacturing | Produces flat glass and vessel glass as the main raw material |
| Electronic industry | High-purity quartz sand is used in semiconductor and photovoltaic industries |
| Foundry industry | Casting sand to improve the surface finish of castings |
3. Market data of quartz sand
According to the hot spot data analysis of the entire network in the past 10 days, the global quartz sand market continues to grow. The following are key data:
