Standards Development

Scope

This document specifies the terms and definitions, principles, test procedures, precision, and test reports of the method for determining the degree of graphitization of graphite materials. This document is applicable for determining the degree of graphitization of graphite materials using X-ray diffraction (XRD).

Purpose

For graphite producers, graphitization degree is one of the key indicators of graphite product quality. Through the accurate graphitization test method, the product quality can be strictly controlled. Only through precise testing methods can we screen products that meet quality standards and ensure their safety and reliability during use.

Graphitic materials with different degrees of graphitisation have very different physical and chemical properties. By testing the degree of graphitization, the relationship between the physical properties of graphite, such as electrical and thermal conductivity, and the degree of graphitisation can be studied. For example, in the field of heat dissipation in electronic devices, highly graphitised graphite has excellent thermal conductivity.

For studying the chemical stability of graphite, graphitization testing is also very important. Graphite with high graphitization tends to have better resistance in chemical corrosive environments. The test method can be used to study the effect of graphitization degree on graphite corrosion resistance and provide theoretical support for its application in corrosive environments such as chemical industry.

 In the field of new material development, accurate graphitization testing helps to develop highperformance graphite composites. For example, in the development of anode materials for lithium-ion batteries, the level of graphitisation affects the charge/discharge performance and cycle life of the battery. Using reliable testing methods can help develop battery anode materials with higher energy density and better cycle performance.

The establishment of uniform and accurate graphitization test methods is crucial for the standardisation of the entire graphite industry. With test method standards, graphite products produced by different enterprises can be evaluated and compared. It is of great significance to regulate the market order, avoid quality disputes caused by inconsistency of test methods and promote the healthy and orderly development of graphite industry.
