The increasing demand for silicon carbide (SiC) in industries such as semiconductors, power electronics, and green energy solutions has put the spotlight on the raw materials needed for its production. Among these, quartz sand plays a pivotal role as it is the source material for high-purity silicon dioxide (SiO2), a crucial component in silicon carbide manufacturing. This research paper delves into the specific purity requirements of quartz sand for SiC plants, examines the production and purification processes, and evaluates how industry leaders like Sinonine are innovating in this field.

Silicon carbide is synthesized through a high-temperature reaction between silica (SiO2) and carbon. The quality of the resulting SiC heavily depends on the purity of the quartz sand used. Impurities in quartz sand, such as iron (Fe), aluminum (Al), or titanium (Ti), can lead to defects in the SiC crystal lattice, reducing its electrical and thermal performance. This makes high-purity quartz sand not just preferable but essential for SiC manufacturing.
For silicon carbide plants, quartz sand typically needs to meet rigorous purity benchmarks. HPQ with a purity level of 99.99% SiO2 or higher is often required. Ultra-high-purity quartz (Ultra HPQ), which exceeds 99.995% SiO2, is preferred for applications demanding even greater material performance, such as in power semiconductors or advanced optoelectronics.
| Purity Level | Applications | Key Considerations |
|---|---|---|
| HPQ (≥99.99% SiO2) | Standard SiC products, electronics | Low impurity tolerance for Fe, Al, Ti |
| Ultra HPQ (>99.995% SiO2) | High-performance SiC, aerospace components | Exceptional purity; negligible contaminants |
Producing HPQ or Ultra HPQ involves overcoming numerous challenges, including eliminating metallic impurities, reducing moisture content, and controlling particle size distribution. Advanced processing techniques such as flotation separation, acid leaching, magnetic separation, and ultrafine grinding are employed to meet these stringent standards.
