T/HPLIA 1301-2026 Greenhouse Gas Product Carbon Footprint Quantification Methods and Requirements High-Entropy Ceramic Coating Materials

Scope

The increasingly frequent human activities have exacerbated global warming, making the conflict between human development and the environment increasingly intense. In recent years, "peaking carbon emissions" and "carbon neutrality" have become the focus of public attention. As a responsible major power in the world, China has actively participated in global climate governance and formulated a carbon reduction strategy based on its national conditions. In his important speech at the general debate of the 75th session of the United Nations General Assembly, President Xi Jinping pointed out that China will increase its national contributions, adopt more effective policies and measures, strive to peak carbon dioxide emissions by 2030, and work hard to achieve carbon neutrality by 2060. As a major industrial manufacturing country, China's high-entropy ceramic coating materials are increasingly being applied in high-end fields such as aerospace, energy, and electronics due to their excellent thermal, mechanical, and chemical properties. The preparation process of high-entropy ceramic coating materials can be divided into several stages, including raw material pretreatment, high-entropy powder synthesis, substrate pretreatment, coating application, drying, and high-temperature heat treatment. Among these stages, the carbon emissions from the high-temperature heat treatment process are the highest, mainly due to the high-temperature thermal energy consumption during electric or gas heating; the second-highest emissions come from the high-entropy powder synthesis process, mainly from the power consumption of high-temperature synthesis equipment and possible precursor decomposition emissions; the remaining emissions can be traced back to the production of high-purity raw materials, logistics transportation, substrate processing, and product post-treatment. Therefore, it is urgent for the high-entropy ceramic coating materials preparation industry to accelerate the process o
