    摘要: The disclosed embodiments relate to a dismantling device configured for a frame of a PV module. The dismantling device includes a connection portion, a first holding portion, and a second holding portion. The first holding portion is connected to the connection portion and configured to press against one of an inner wall and outer wall of the frame. The second holding portion is slidably disposed on the connection portion and movably closer to or away from the first holding portion along a sliding direction. The second holding portion is configured to press against the other one of the inner wall and the outer wall so as to clamp the frame with the first holding portion and to distort the frame.

    摘要: A method of purifying silicon carbide powder includes: providing a container with a surface coated by a nitrogen-removal metal layer, wherein the nitrogen-removal metal layer is tantalum, niobium, tungsten, or a combination thereof; putting a silicon carbide powder into the container to contact the nitrogen-removal metal layer; and heating the silicon carbide powder under an inert gas at a pressure of 400 torr to 760 torr at 1700° C. to 2300° C. for 2 to 10 hours, thereby reducing the nitrogen content of the silicon carbide powder.
