Embodiment 1

[0037] A kind of embodiment of the preparation method of cadmium stannate metallographic sample of the present invention, comprises the following steps:

[0038] (1) According to the metallographic sample preparation standard, the cadmium stannate target material is cut into cadmium stannate sample A by wire cutting;

[0039] (2) Grinding the cadmium stannate sample A: the sample is first polished with 400 mesh water-based sandpaper, and the sandpaper of a predetermined specification is fixed on the electric turntable of the polishing machine during grinding, and pure water is used as a wetting agent. Let the electric turntable rotate clockwise and set the speed at 200r / min to grind for 1min. When polishing, place the cadmium stannate sample A in the direction perpendicular to the wire cutting pattern and the rotation tangent of the electric turntable, and apply 20N vertical downward force to the sample at the same time. Then the sample is rotated 180 ° and polished for 1min i...

Abstract

The invention discloses a cadmium stannate metallographic specimen and a preparation method thereof, and belongs to the field of industrial material preparation. According to the preparation method of the cadmium stannate metallographic specimen, the cadmium stannate specimen is subjected to specific grinding and mechanical polishing treatment, so that the defect that the metallographic phase is blurred during observation due to the fact that an inclined plane appears in the traditional grinding process can be effectively avoided; after the metallographic sample is subjected to subsequent surface chemical corrosion treatment, the microscopic structure can be clearly and completely observed under microscopic observation, and the sample has no obvious scratch, defect or pit defect; the method has the advantages of simple operation steps, low cost and short time consumption, and has practical significance in the aspects of evaluating the grain condition of the cadmium stannate target material and researching the performance. The invention further discloses the cadmium stannate metallographic specimen obtained through the preparation method of the cadmium stannate metallographic specimen, the surface of the product is flat, smooth and flawless, the microstructure is clear under microscopic observation, and effective evaluation on the grain size and uniformity of the product can be achieved.

Description

technical field [0001] The invention relates to the field of industrial material preparation, in particular to a metallographic sample of cadmium stannate and a preparation method thereof. Background technique [0002] Transparent conductive films are mainly divided into three categories: metal films, oxide films and other compound films. Cadmium stannate film has become one of the most widely studied compound films in recent years because of its excellent electrical and optical properties. At present, the cadmium stannate film is mainly prepared by sputtering the cadmium stannate target material, so the performance of the cadmium stannate target material has a direct impact on the performance of the film. Since the grain size and uniformity are one of the important factors affecting the performance of the cadmium stannate target, it is of high practical value to observe the grain size and uniformity of the cadmium stannate target. [0003] In the prior art, when detecting...
