Graphite sintering table for Joule thermal shock method

Abstract

The utility model discloses a graphite sintering table for a Joule thermal shock method. A main body of the graphite sintering table is in a hollow cylinder shape, and the section area of the middle of the graphite sintering table perpendicular to the cylinder direction is smaller than the section area of the end of the graphite sintering table perpendicular to the cylinder direction. The section area, perpendicular to the length direction of the strip shape, of the middle of the graphite sintering table is designed to be smaller than the section area, perpendicular to the length direction of the strip shape, of the end of the graphite sintering table, so that the resistance of the middle is large, the resistance of the end is small, and it is guaranteed that in the Joule heating process, temperature rise of the middle is fast, and temperature rise of the end is slow; therefore, the temperature of the end part is relatively low while the sample reaches the heating temperature, and the electrode cannot be burnt.

Description

Technical Field

[0001] This utility model relates to a graphite sintering table, and more particularly to a graphite sintering table for the Joule thermal shock method. Background Technology

[0002] Current techniques for preparing materials using Joule thermal shock involve wrapping the material in carbon cloth and then sandwiching the cylindrical carbon cloth between two electrodes. This method is cumbersome, involves complex sample preparation, and the sample wrapping is prone to leakage. Uneven thermal conduction also occurs, with the ends of the electrodes often heating first before the temperature is transferred to the middle, potentially leading to overheating and electrode burnout. Utility Model Content

[0003] This application employs a graphite sintering stage for the Joule thermal shock method, which solves the problems of cumbersome operation and easy damage to heating electrodes in the prior art.

[0004] This application provides the following technical solution: a graphite sintering platform for the Joule thermal shock method, wherein the main body of the graphite sintering platform is a hollow strip, and the cross-sectional area of ​​the middle part of the graphite sintering platform perpendicular to the length direction of the strip is smaller than the cross-sectional area of ​​the end part of the graphite sintering platform perpendicular to the length direction of the strip.

[0005] Furthermore, the main body of the graphite sintering platform is cylindrical or rectangular.

[0006] Furthermore, the hollow shape of the graphite sintering platform is a spindle shape, which is larger in the middle and smaller at both ends.

[0007] Furthermore, the hollow shape of the graphite sintering platform is a stepped shape that is larger in the middle and smaller at both ends.

[0008] Furthermore, the hollow shape of the graphite sintering platform is cylindrical, and the outer surfaces at both ends of the graphite sintering platform have raised annular steps.

[0009] The beneficial effects of this application are as follows:

[0010] (1) The graphite sintering table is easy to operate;

[0011] (2) By designing the cross-sectional area of ​​the middle part of the graphite sintering stage perpendicular to the length of the strip to be smaller than the cross-sectional area of ​​the end part of the graphite sintering stage perpendicular to the length of the strip, the resistance in the middle part is large and the resistance at the end part is small. This ensures that the middle part heats up faster and the end part heats up slower during Joule heating, thus ensuring that the temperature at the end part is low while the sample reaches the heating temperature, and the electrode will not be burned.

[0020] This application simplifies the loading and preparation of raw materials by designing a graphite sintering stage, while protecting the electrodes during the sintering process.

[0021] The embodiments of this utility model will be further described below with reference to several examples.

[0022] Example 1

[0023] like Figures 1-2 A graphite sintering platform for the Joule thermal shock method is disclosed. The main body of the graphite sintering platform is a hollow cylinder. The cross-sectional area of ​​the middle part 1 of the graphite sintering platform perpendicular to the length of the cylinder is smaller than the cross-sectional area of ​​the end part 2 of the graphite sintering platform perpendicular to the cylinder. The hollow shape of the graphite sintering platform is a spindle shape, larger in the middle and smaller at both ends.

[0024] By designing the cross-sectional area of ​​the middle part 1 of the graphite sintering stage perpendicular to the cylindrical direction to be smaller than the cross-sectional area of ​​the end part 2 of the graphite sintering stage perpendicular to the cylindrical direction, the resistance of the middle part 1 is large and the resistance of the end part 2 is small. This ensures that the middle part 1 heats up faster and the end part 2 heats up slower during Joule heating, thus ensuring that the temperature of the end part 2 is low while the sample reaches the heating temperature, and the electrode will not burn out.

[0025] Example 2

[0026] like Figures 3-4A graphite sintering platform for the Joule thermal shock method is disclosed. The main body of the graphite sintering platform is a hollow cylinder. The cross-sectional area of ​​the middle part 1 of the graphite sintering platform perpendicular to the length of the cylinder is smaller than the cross-sectional area of ​​the end part 2 of the graphite sintering platform perpendicular to the cylinder. The hollow shape of the graphite sintering platform is cylindrical, and the outer surface of the end part 2 of the graphite sintering platform has a raised annular step. In this embodiment, the graphite sintering platform has a dumbbell shape.

[0027] By designing the cross-sectional area of ​​the middle part 1 of the graphite sintering stage perpendicular to the cylindrical direction to be smaller than the cross-sectional area of ​​the end part 2 of the graphite sintering stage perpendicular to the cylindrical direction, the resistance of the middle part 1 is large and the resistance of the end part 2 is small. This ensures that the middle part 1 heats up faster and the end part 2 heats up slower during Joule heating, thus ensuring that the temperature of the end part 2 is low while the sample reaches the heating temperature, and the electrode will not burn out.

[0028] Example 3

[0029] like Figures 5-6 A graphite sintering platform for the Joule thermal shock process is disclosed. The main body of the graphite sintering platform is a hollow cube. The cross-sectional area of ​​the middle part 1 of the graphite sintering platform perpendicular to the cube direction is smaller than the cross-sectional area of ​​the end part 2 of the graphite sintering platform perpendicular to the cylindrical direction. The hollow shape of the graphite sintering platform is stepped.

[0030] By designing the cross-sectional area of ​​the middle part 1 of the graphite sintering stage perpendicular to the length of the strip to be smaller than the cross-sectional area of ​​the end part 2 of the graphite sintering stage perpendicular to the length of the strip, the resistance of the middle part 1 is large and the resistance of the end part 2 is small. This ensures that the middle part 1 heats up faster and the end part 2 heats up slower during Joule heating, thus ensuring that the temperature of the end part 2 is low while the sample reaches the heating temperature, and the electrode will not burn out.
