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...

Abstract

The invention discloses an apparatus and a method used for synthesizing zinc germanium diphosphide polycrystalline. The apparatus comprises a crucible, a heating furnace, and a motor. An explosion-proof steel pipe is arranged in the heating furnace, and the crucible is arranged in the explosion-proof steel pipe. The motor is connected to the inner part of the explosion-proof steel pipe through a linkage bar. According to the invention, the crucible is rotated, such that phosphor can subject to a sufficient reaction, and the yield and the purity of the grown zinc germanium diphosphide polycrystalline are high. Also, the yield of the zinc germanium diphosphide polycrystalline obtained through one time of synthesizing is large. Therefore, the apparatus and the method are suitable to be popularized.

Description

Technical field [0001] The invention involves the growth technology field of phosphate zinc polycrystals, and specially involves a synthetic device and method of a phosphate zinc polycrystal. Background technique [0002] Seminar semiconductor crystals are non -linear optical crystals.It has two prominent advantages: non -linear optical coefficients and Zhongyuan infrared areas are wide through the band.Phosphorus -based zinc crystals are the best comprehensive performance in brass mineral semiconductor crystals.Compared with other brass mineral semiconductor crystals, phosphorus zinc crystals also have their own special properties: 1. Wide through the band, from 0.7um to 12um;It is not easy to cause damage to the crystal and optical components;Therefore, the military application prospects and civilian prospects of such crystals are very broad.Its military field is widely used: laser -directional infrared interference, laser communication, infrared ranging, infrared remote sensin...
