Growing Demand for High-Purity Silicon: A Game Changer for the Semiconductor and Battery Industries

In recent months, the demand for high-purity silicon materials has surged, marking a major change in the semiconductor and battery industries. This shift is mainly due to technological advances and the need for more efficient and reliable materials. It is worth mentioning that Jiangsu Changdian Technology Co., Ltd. has attracted widespread attention for producing silica sol using 2202# industrial silicon (which has extremely low trace metal content, Fe≤0.02%, Cu+Ti≤5ppm). This innovative technology has achieved an astonishing chip packaging yield of more than 99.3%, effectively replacing materials previously imported from Japan.

In the battery field, CATL fully utilized the potential of 421# industrial silicon (Fe≤0.2%, boron and phosphorus impurities≤30ppm) to synthesize nano-silicon powder. This breakthrough has made the Kirin battery a super-fast charging time of only 13 minutes and an energy density increase of 40%. These advances not only improve battery performance, but also pave the way for more sustainable energy solutions.

In addition, in the market of silicone cross-linkers, the share of 3303# industrial silicon has been steadily increasing due to its stable oxygen content (≤0.3%); in addition, the penetration rate of 521# titanium silicon in the photovoltaic crucible coating market has also increased at an astonishing rate of 25% per year.

The future of high-purity silicon looks bright as global customers seek customized high-purity grade technology solutions for specific applications, from semiconductor packaging to silicon-based anodes and specialty ceramics. This trend not only marks a leap forward in materials science, but also highlights the key role of high-purity silicon in driving innovation in various technology fields.
