[0020] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the crucible structure for precious metal sintering reaction of the utility model comprises a crucible body 1 and a crucible cover 2, the crucible body 1 comprises a crucible side wall 11 and a crucible cavity 12, the crucible cavity 12 is arranged in the middle of the crucible side wall 11, the crucible cover 2 comprises a cover top plate 21 and a cover side wall 22, the cover side wall 22 is connected to the bottom of the cover top plate 21, and also comprises at least two support piers 5, the support piers 5 are arranged between the lower surface of the cover top plate 21 and the top of the crucible side wall 11 at intervals;

[0022] At least two spaced support piers 5 are connected and arranged below the cover top plate 21. The support piers 5 are detachably arranged on the top of the crucible side wall 11. The cover side wall 22 is arranged on the outside of the crucible side wall 11. A first exhaust channel 3 is arranged between the top of the crucible side wall 11 and the cover top plate 21. A second exhaust channel 4 is arranged between the cover side wall 22 and the crucible side wall 11. The first exhaust channel 3 is connected to the crucible cavity 12, and the second exhaust channel 4 is connected to the first exhaust channel 3.

[0023] The function of the support pier 5 is that when the crucible cover 2 is placed above the crucible body 1, a first exhaust channel 3 is formed between the top of the crucible side wall 11 and the cover top plate 21, and a second exhaust channel 4 is formed between the cover side wall 22 and the crucible side wall 11. The support pier 5 can be connected and arranged below the cover top plate 21, such as Figure 3 As shown, the support pier 5 can be connected to the top of the crucible side wall 11, such as Figure 4 shown.
