Standards Development

Scope

The document specifies a test method for analyzing the carbon content of graphite ore and its products.

This document applies to natural graphite ore and its products.

Purpose

Carbon content is one of the important indicators of natural graphite ore and graphite products, which directly affects physical and chemical properties of graphite, and also has the function of distinguishing graphite product categories. The higher the carbon content in natural graphite ore, the better the purity of graphite, and the higher its application value. Graphite with high carbon content has good electrical conductivity, high temperature resistance, chemical stability, strength and other properties. It is commonly used in high-end fields such as electronics, optics, and chemical engineering. However, there is no unified and standardized carbon content determination method in the current graphite international market, which affects international trade of graphite ore and graphite products as well as the cooperation between upstream and downstream enterprises. Therefore, the purpose and justification of this standard proposal is as follows. (1).The reserves of graphite resources have exceeded 280 million tons, covering many countries in the world, China's natural graphite reserves are the highest, about 78 million tons, accounting for 28% of global reserves, which can provide resource guarantee for the development of the world economy, and the determination method standard of graphite carbon content is conducive to protecting the quality level of graphite mineral resources. (2). Global graphite production capacity of more than 1.6 million tons, trade characteristics for the demand side is relatively dispersed, the supply side is highly concentrated, relatively excess production capacity, China's natural graphite production is the highest, about 1.23 million tons, accounting for 77% of global production, graphite carbon content determination method standards can provide technical support for the trade of graphite products in various countries, reduce the waste of graphite resources. (3).Graphite is listed as strategic mineral resources by many countries. It is an indispensable strategic resource for the development of modern industry and military industry. It is also a key resource for high-end equipment manufacturing, new energy, new materials and other strategic emerging industries and nuclear power field, graphite carbon content determination method standards contribute to the high-quality development of graphite industry. (4).To formulate a unified standard for the detection and analysis method of the carbon content of graphite, and fill the standard blank in the field of ISO graphite chemical analysis. (5).It provides standard technical support for graphite resource analysis and graphite product quality level analysis, ensures the product quality level of graphite resources and graphite processing enterprises, and contributes to the selection of graphite mines and graphite products in traditional application fields and high-end application fields. (6).Reduce analysis and testing costs, improve product quality, promote international exchanges and cooperation among graphiterelated enterprises, and break trade barriers in the international market.
