Float Zone Crystal Grower from China
A float zone crystal grower uses the float zone method to produce high-purity monocrystalline silicon boules by melting a polycrystalline rod with a radio-frequency coil and moving the molten zone. It is ideal for oxygen-free crystals used in power semiconductors. Classified under HTS 8486.10.00.00 for boule manufacturing equipment.
