The bonding quality of the SiC seed crystals is one of the most basic and most important influence factors influencing crystal growth, the bonding quality directly determines the quality of the crystals, and the crystals are difficult to remedy or improve through control of other technological parameters. A weight is added on the upper surface of the seed crystals, and the weight applies a vertically downward acting force so that gas escape is facilitated. A fixed ring is designed to ensure that the seed crystals do not deviate. The fixed ring is made of high-purity graphite so that pollution of other materials is reduced. The height of the fixed ring is 20-50 mm, and the thickness of the fixed ring is 5-10 mm. In order to reduce the temperature gradient and improve the uniformity of seed crystal bonding, a circle of high-purity graphite felt wraps the periphery of the fixed ring, and the height of the high-purity graphite felt is the same as that of the fixed ring. The graphite felt reduces the pollution to the graphite cover and the seed crystals, enhances the heat preservation property, and reduces the temperature gradient inside and outside the graphite cover.
