These furnaces are used to grow silicon ingots and are also capable of producing germanium and gallium arsenide crystal ingots. Kayex’s state-of-the-art solar crystal growing furnaces also utilize the Czochralski method. This line of furnaces produces crystals used in alternative energy solutions. These high-temperature crystal growers utilize the Czochralski or CZ method of crystal growing. The crystallization process begins when highly pure material is melted and a seed crystal is dipped into the molten material and made to grow. The crystal increases in size as the seed is slowly raised from the melt, which is why the crystal growing furnace is often referred to as a "crystal puller."
