    • The present invention relates to a device capable of collecting high-purity tellurium powder in high demand as a thermoelectric material or a photoelectric material and a method for manufacturing tellurium powder and, more specifically, to a device for manufacturing a high-purity tellurium powder including a carrier gas inlet and a furnace capable of being partially heated and a technology capable of controlling the particle size of the high-purity tellurium powder by injecting carrier gas. The present invention can collect purer tellurium powder than the tellurium powder manufactured by an existing powder manufacturing method such as a ball-milling method, which manufactures the tellurium powder by mechanically grinding solid tellurium, and a method using atomization after melting; can manufacture nanopowder by controlling the temperature of a collecting tank; and can control the particle size of deposited powder. Especially, the present invention obtains excellent economic efficiency as the high-purity tellurium powder in 5N or higher class of metallurgical grade can be manufactured through a single step using a low-purity tellurium material of 2N metallurgical grade. Furthermore, the purity of the 5N-class tellurium and the nanopowder manufactured by the present method can be useful for improving thermoelectric and photoelectric properties in consideration of the utilization of the tellurium powder for a thermoelectric material or a photoelectric material.
