FBR granular silicon

GCL Tech's commitment to research over the past decade has paid off with the successful development of FBR granular silicon, our breakthrough core product that fills the gap of the 100,000-ton granular silicon production capacity in the world.FBR granular silicon has obtained carbon footprint certification from China, France, and Germany, breaking the carbon footprint record previously held by Siemens method rod silicon and establishing itself as the new benchmark for carbon footprint in the international semiconductor materials industry.

Product Features

High quality, can reach electronic grade standards

The quality of FBR granular silicon products is excellent and has passed the verification of N-type monocrystals; it is spherical in shape, has good fluidity, better meets the size requirements of re-feeding, and the efficiency of re-feeding has been improved.

Purity can reach electronic grade to meet the needs of the N-type supply chain

Better meet the technical requirements of RCz and CCz monocrystalline silicon

FBR technology with independent intellectual property rights

Low cost, excellent carbon footprint performance

Based on GCL's granular silicon achieving certification from the French Environment and Energy Management Agency (ADEME) in 2021, with a conservative calculation of 37 kg CO₂ equivalent, granular silicon used in downstream production can reduce approximately 240,000 tons of carbon emissions per 10,000 tons compared to the best level of rod silicon. Each 10,000 tons of granular silicon will contribute over 129 million yuan in carbon reduction value to society.
