Description

Technical Field

[0001] This utility model belongs to the field of sample testing, specifically relating to an X-ray diffraction sample disk. Background Technology

[0002] X-ray diffraction (XRD) is a non-destructive, high-precision, and widely applicable technique that can rapidly and accurately identify the phase composition and crystal structure of substances. It has significant applications in new material development, alloy analysis, mineral identification, and archaeological artifact authentication. In addition to conventional powder testing, an increasing number of bulk materials require XRD for testing of phase composition, grain size, microstress, and crystallinity.

[0003] Currently, when a polycrystalline X-ray diffractometer is equipped with a 90-position autosampler and a rotating sample stage, the accompanying conventional solid disk, such as... Figure 7 As shown, the groove depth is approximately 6 mm and the inner diameter is approximately 40 mm. This sample tray can accommodate large test surfaces, but it has significant limitations regarding the height of the test surfaces. In actual sample preparation and testing, some test surfaces need to be thinned by 0-2 mm to meet the sample preparation requirements (the test surface of the test surface should be flush with the height of the sample tray), which places high demands on the pretreatment of the test surfaces. Therefore, to address the above situation, a sample tray is needed to overcome the limitations of conventional solid-state trays. Utility Model Content

[0004] The purpose of this invention is to propose an X-ray diffraction sample disk that addresses the limitations of conventional solid disks.

[0005] Therefore, this utility model provides an X-ray diffraction sample disk, comprising:

[0006] A disc and a base, wherein the base is fixedly installed on the bottom of the disc, and a first groove is provided inside the disc, and a second groove is provided on the bottom surface of the first groove, extending into the base.

[0007] Preferably, the disc and the base are integrally formed.

[0008] Preferably, the bottom surface of the first groove is circular.

[0009] Preferably, the second groove is circular or rectangular.

[0010] Preferably, the center line of the second groove is on the same straight line as the center line of the first groove.

[0011] Preferably, the base is cylindrical or cuboid in shape.

[0012] Preferably, when the base is a cylinder, the outer diameter of the bottom surface is less than or equal to 38 mm, the height is less than or equal to 17 mm, and the wall thickness is greater than or equal to 2.5 mm.

[0013] Preferably, when the base is a cuboid, the outer diagonal of the bottom surface is less than or equal to 38mm, the height is less than or equal to 17mm, and the wall thickness is greater than or equal to 2.5mm.

[0014] Preferably, the side wall of the disk is provided with a slot.

[0015] Preferably, the material of the disc and the base is plexiglass.

[0016] Beneficial effects:

[0017] This utility model discloses an X-ray diffraction sample disk. By adding a base under the disk, it is possible to prepare and test more thick block samples. The size of the sample disk meets the requirements of the rotating sample stage of a 90-position autosampler. The sample disk can be manually placed on the rotating sample stage for rotational testing. Attached Figure Description

[0027] The following detailed description of preferred embodiments of the present invention, along with the included examples, will make the content of the present invention more readily understood. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. In case of any conflict, the definitions in this specification shall prevail.

[0028] Provided such as Figure 1-2 An X-ray diffraction sample tray is shown, comprising: a disc 1 and a base 2. The base 2 is fixedly installed at the bottom of the disc 1. A first groove 3 is provided inside the disc 1, and a second groove 4 extending through the bottom surface of the first groove 3 into the base 2 is provided. The first groove 3 is the initial placement space for the sample block, and its bottom surface is circular to accommodate the test surface shape of most sample blocks. The second groove 4 extends from the bottom surface of the first groove 3 into the interior of the base 2, forming a deep groove structure, which is the core space for accommodating thick sample blocks. Compared with the conventional sample tray with a groove depth of only 6mm, the second groove 4, with the help of the depth of the base 2, can directly place taller sample blocks without additional thinning treatment, thus solving the limitation of traditional sample trays on sample height.

[0029] The disc 1 and the base 2 are integrally molded, and both are made of plexiglass. This integral design avoids sample placement misalignment caused by assembly gaps, enhances structural stability, and is suitable for the high sample positioning accuracy requirements of precision XRD testing.

The centerline of the second groove 4 is collinear with the centerline of the first groove 3. The centerlines of the first groove 3 and the second groove 4 coincide, ensuring that the sample is placed in the center of the sample tray so that X-rays irradiate the effective test surface.

[0031] The base 2 is cylindrical or cuboid. When the base 2 is cylindrical, the outer diameter of the base is less than or equal to 38mm, the height is less than or equal to 17mm, and the wall thickness is greater than or equal to 2.5mm. When the base 2 is cuboid, the outer diagonal of the base is less than or equal to 38mm, the height is less than or equal to 17mm, and the wall thickness is greater than or equal to 2.5mm.

[0032] A slot 5 is provided on the side wall of the disc 1. When placed on a rotating sample stage, the slot 5 can be used by a robotic arm to grasp the sample disc.
