Embodiment 1
[0041] like figure 1 It shows that a synthetic device of a zinc -zinc polycrystal, including 坩埚 1 and heating furnace 3, also includes motor 37.The heating furnace 3 has a furnace shell 36, which is equipped with explosion -proof steel pipes 33.The heating furnace 3 is the horizontal furnace of the eight -temperature zone. There is an explosion -proof steel pipe 33 in the horizontal furnace of the Baben area.EssenceAmong them, 34 is a mixture of zinc and 4; 35 is phosphorus.
[0042] like image 3 Show, 坩埚 1 includes sealing tube 11, cylindrical 12 and transport tube 13.The inner diameter N of the sealing tube 11 is less than the inner diameter R of the cylindrical 12; the inner diameter R of the cylinder 12 is 10mm, and the length S is 90mm; the length F of the sealing tube 11 is 190mm, and the length K of the transport tube 13 is 750mm.
[0043] like figure 2 It also includes auxiliary feed pipe 2, the auxiliary feed pipe includes the guide tube 23, one end of the guide pipe is equ...
Embodiment 2
[0066] Except for the following features, other characteristics are the same as Example 1: Figure 7 It is shown in the X -ray powder diffraction diagram of this embodiment; in this embodiment, the specific operation is as follows:
[0067] (1) Installation and packaging
[0068] According to chemical measurement, phosphorus: 锗: zinc = 1: 1: 2 weighing raw materials; fully mix zinc and 锗 uniformly; first install the phosphorus through auxiliary loading tube 2 into the bottom of 坩埚 1, and then zinc and 锗 锗 锗 锗The mixture is loaded into the cylinder 12 in the 坩埚 1 by the auxiliary installation tube 2, and the above process is completed in the glove box; finally, take the 坩埚 1 from the glove box, and the 坩埚 坩埚 is vacuum to 10 to 10 -4 PA seal;
[0069] (2) Rotating auxiliary growth
[0070] a) Put the sealing 1 in the heating furnace, place the bottom end of the phosphorus in a low temperature zone, and place the cylinder 12 of zinc and crickets in the high temperature zone; thenThe c...
