African Quartz Growth will acquire the Czochralski crystal-growing system EKZ 3500 has been specially designed for industrial production of monocrystalline Silicon crystals. The Czochralski process is also known as “crystal pulling” or “pulling from the melt”. In this process, Silicon (Si) is first melted and then allowed to freeze into a crystalline state in a controlled manner. The advantage of this method is that it is fast and highly controllable. The industrial cultivation of high-purity monocrystalline Silicon crystals using the Cz Process has become well established primarily for the solar and semiconductor industries (in the computer industry for integrated circuits and in microsystem technology). The company benefits from the high effectiveness and quality of the cultivated crystals. The hot zone can be charged with up to 150 kg of Silicon and can produce crystals with a diameter of up to 300 mm (12″). The maximum crystal pulling rate is 10 mm/min, while the maximum crystal and crucible rotation rate is 35 rpm. A camera system for measuring the diameter and two pyrometers for measuring the temperature allow automatic process control by means of a PLC and PC. Monocrystalline silicon is then used by the Silicon Photovoltaic Module Manufacturing Factory to produce conventional mono-Si solar cells.
