Overview
In photovoltaics, high-purity quartz sand is the feedstock for quartz crucibles — an indispensable material in the crystalline-silicon chain. The crucible touches the silicon melt directly, so trace elements, particle-size distribution and bubble/ inclusion level determine devitrification behaviour, crucible life and final wafer yield.
Key Indicators
| Indicator | Why it matters |
|---|---|
| SiO₂ purity | Drives devitrification and contamination at the crucible wall |
| Trace elements (Fe, Al, Na, K, Li) | Alkali metals and iron migrate into the melt and shorten minority-carrier lifetime |
| Particle-size distribution | Affects packing density, sintering behaviour and wall-thickness uniformity |
| Bubble and inclusion level | Releases gas at temperature, creating wall defects |
Background
In 2023 the company took a controlling stake in Lihui New Materials to add high-purity quartz sand — an upstream link in the PV chain.
Delivery
Diameter, strength, spool length and packaging are confirmed against the machine and duty; MOQ, sampling and production lead time on inquiry.
