Description
Technical Field
The application relates to a method for improving fluidity of cadmium selenide powder, belonging to the technical field of powder materials.
Background
Cadmium selenide (CdSe) is an n-type semiconductor material, and has a narrow direct transition band gap structure (1.76 eV), so that the cadmium selenide can effectively absorb energy of visible light, and has been widely applied to the fields of photoelectrochemical solar cells, photoelectrochemical detection, photocatalysts, gas sensors and the like. The nano semiconductor material has quantum size effect, surface effect, dielectric finite field effect and other properties, such as unique optical, electrical, magneto-thermal and other properties, compared with other organic or inorganic materials, which are closely related to the size of nano semiconductor crystal grains. Thus, by controlling the synthesis conditions, the grain size can be varied to varying degrees, and the absorption and luminescence properties of the material will undergo a corresponding red or blue shift as the size of the nanocrystalline grain increases or decreases. As a direct band gap II-VI semiconductor material, the CdSe material has a band gap width of 1.74eV and a narrow emission spectrum, and the emission wavelength range of the CdSe material can be adjusted by changing the size of the nano crystal, so that the CdSe nano crystal can be applied to the fields of biological markers and fluorescent display and is widely applied to photoelectric devices, biological sensing, solar cells, light-emitting diodes, piezoelectric materials, laser materials and the like.
The flowability of the powder is related to the shape, size, surface state, density, void fraction, etc. of the particles. The weight difference in the preparation of the granules and the normal operation are greatly affected. The powder flow includes gravity flow, compression flow, fluidization flow and other forms. The powder flows, the essence is unbalance of particle stress in the powder, and the stress analysis of the particles shows that the acting force of the particles has gravity, inter-particle adhesion, friction, electrostatic force and the like, and the influence on the powder flowing is the gravity and the inter-particle adhesion. The factors influencing the flowability of the powder are very complex, and the particle size distribution and the particle shape have an important influence on the flowability of the powder. In addition, factors such as temperature, moisture content, electrostatic voltage, void fraction, bulk density, adhesion index, internal friction coefficient, humidity in air and the like also affect the flowability of the powder. The flowability of the powder is related to particle size, particle size distribution, particle morphology, surface state, bulk density, etc., and can be evaluated by angle of repose [ α ], internal friction angle [ θ ], shear adhesion, etc. The common method is to measure the repose angle, and the repose angle alpha is generally considered to be good in fluidity when less than 30 degrees, poor in fluidity when more than 45 degrees, but in actual production, alpha is less than 40 degrees, the production requirement of the split dosage can be met, and the fluidity of the powder can be expressed by Hall flow rate.
In practical production application, the fluidity of the powder material is highly required, and in the prior art, the fluidity of the powder material is often improved by doping other auxiliary materials into the powder material, so that the introduced impurities can influence the application of the powder material.

(2) Deoxidizing the cadmium selenide particles A to obtain cadmium selenide particles B;
(3) And (3) barreling the cadmium selenide particles B to obtain the cadmium selenide powder.
Cadmium selenide is an n-type semiconductor material and is widely applied to the fields of photoelectrochemical solar cells, photoelectrochemical detection, photocatalysts, gas sensors and the like. In practical production and application, there is a high requirement on the fluidity of cadmium selenide powder, and no report on how to improve the fluidity of cadmium selenide powder is available in the prior art. The method for improving the fluidity of the cadmium selenide powder provided by the application has the advantages of simple preparation steps, lower equipment requirement, lower cost and high fluidity of the prepared cadmium selenide powder.

As a preferred embodiment of the method for improving the fluidity of cadmium selenide powder, the twice crushing treatment is as follows: the cadmium selenide ingot was crushed to <10mm particles and then crushed to <300 μm particles by a mill. The application carries out twice crushing treatment on the cadmium selenide ingot, so that the particles of the cadmium selenide ingot are smaller, and the subsequent preparation is convenient to improve the fluidity of the cadmium selenide powder.
As a preferred embodiment of the method for improving fluidity of cadmium selenide powder according to the present application, the deoxidizing temperature in the step (2) is 700 to 1000 ℃. The inventor of the present application has found that after the cadmium selenide ingot is directly crushed, the powder surface adsorbs a lot of fine powder, and the fine powder is extremely easy to oxidize on the surface of cadmium selenide particles, so that the fine powder on the surface of the particles needs to be removed through deoxidization treatment, and at the deoxidization temperature, the fine powder on the surface of the cadmium selenide particles can be removed cleanly without causing excessive deoxidization.
