Description

Technical Field

[0001] The utility model relates to the technical field of carbon powder processing, in particular to a high-temperature purification device for carbon powder. Background Art

[0002] High-purity carbon powder is typically purified in a purification furnace. Halogen gas is introduced at temperatures exceeding 2200°C to induce a reaction, removing impurities from the powder. Existing purification furnaces primarily utilize vacuum purification furnaces, which not only achieve high purity but also effectively remove specific impurities. Graphite crucibles are ideal containers for holding carbon powder in high-temperature purification environments. These crucibles are placed in a vacuum purification furnace to heat and ventilate the furnace to achieve purification.

[0003] Common graphite crucibles are medium-coarse graphite processing containers with lids. They have poor air permeability, making it difficult for purified gas to effectively enter the crucible and come into contact with carbon powder. As a result, the purification ventilation volume far exceeds the actual demand for the reaction gas, resulting in gas waste, long production time and increased energy consumption.
