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 certificates in both China and France, breaking the carbon footprint record held by rod silicon produced using the Siemens method and becoming the new benchmark of global pan-semiconductor materials in terms of carbon footprint.

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

Since the carbon footprint of 1 kilogram of FBR granular silicon was certified by French Environment and Energy Management Agency (ADEME) to be equivalent to 37 kilograms of carbon dioxide in 2021, every 10,000 tons of granular silicon produced for downstream production will reduce CO2 emissions by about 240,000 tons than rod-shaped silicon produced by the optimal process, creating over RMB 129 million of carbon reduction value for society.
