Float Zone Crystal Grower from Germany

Centrifugal apparatus employing the float zone method to purify and grow semiconductor crystals like silicon by melting and recrystallizing zones in a controlled inert gas environment with dust filtration. Classified under HTS 8421.39.0115 due to its built-in air purification systems that filter out particulates to prevent contamination during high-vacuum zone refining. Critical for producing ultra-pure silicon ingots for wafer slicing.
