Ferrosilicon serye 65-75% ajan gri fesi

Patikil ferrosilikon yo se yon alyaj fè ki konpoze de fè ak Silisyòm. Ultra-segondè-pite Fesi (99.9% si, Fe <0. 1%) sèvi kòm yon pri-efikas précurseur pou polisilikon yo itilize nan selil solè ak semi-kondiktè. Pwosesis raffinage idrometallurgical nou an retire tras bor (<1 ppm) and phosphorus (<2 ppm), critical for achieving >22% efikasite selil solè.

Disponib nan 1-5 mm poud fòm, FESI nou an asire inifòm dopan nan czochralski Silisyòm kristal kwasans. Vakyòm-sele 25kg tanbou anpeche oksidasyon pandan transpò piblik, ak kontni imidite<0.01%. In order to obtain steel with qualified chemical composition and ensure the quality of steel, deoxidation must be carried out in the final stage of steelmaking. The chemical affinity between silicon and oxygen is very large, so ferrosilicon is a strong deoxidizer for steelmaking, playing a role in precipitation and diffusion. deoxidation.
