Abstract: The present disclosure provides an apparatus and method for growing high-quality silicon carbide crystals and silicon carbide crystals, and relates to the technical field of the silicon carbide crystals. In the apparatus, a pressure equalizing structure is arranged on the annular guide plate, a pressure difference between a second chamber above the annular guide plate and a first chamber below the annular guide plate can be effectively reduced, and the flow rate of the gaseous-phase crystal growth components at a gap between a top end of the annular guide plate and an edge of the seed crystal can be effectively reduced accordingly, and then the defects such as a “concave interface” on the silicon carbide crystals growing on the seed crystal are avoided, thereby improving the growth quality of the silicon carbide crystals. The silicon carbide crystals prepared by the method have characteristics of fewer defects and high quality.

Abstract: A peristaltic pump includes a frame, a tube, and a rotor, the tube being fitted in the frame. The rotor includes a rotary member and a roller, wherein the rotary member is rotatable relative to the frame, and the roller is movable along the tube for squeezing the tube to pump fluid in the tube, when the rotary member is rotated. The roller is connected to the rotary member in such a manner as to allow the roller to move between a first position that squeezes the tube and a second position that releases, i.e. does not squeeze, the tube, thereby avoiding permanent plastic deformation of the tube.
