Thermal conductive powders currently used to fill composite thermally conductive materials can be divided into multiple categories. According to the chemical composition of the material, it can be divided into three categories: metal, carbon powder and inorganic non-metallic powder. Oxide metal powder has good advantages in the field of preparing high thermal conductivity composite materials due to its good thermal conductivity and insulation properties.

Main drivers:
- National policy support: Policy support is the core driving force for industry development.
- As the functions of electronic products such as 5G communication equipment and high-end smartphones become increasingly complex and miniaturized, thermal interface materials solve the heat dissipation problem of core components of electronic products, thus driving the demand for spherical alumina. Thermal interface materials continue growing, with increasing requirements for conductive fillers, media purity, and radioactivity.
- new energy vehicles are showing a strong trend of replacing traditional energy vehicles, and market sales are gradually expanding. Power batteries are the core of new energy vehicles. Adhesives used in power batteries can effectively improve their performance and play a key role in achieving stability, efficiency, and safety. The demand for spherical alumina for new energy vehicle power battery adhesives will grow rapidly.
Main obstacles:
- The technical barriers to spherical alumina are relatively high. The biggest technical difficulty lies in the research and development of the spheroidization process and production equipment. There are currently no standard devices on the market. If new companies want to build new production capacity and produce spherical alumina with excellent quality and stability, they need to overcome relevant technical bottlenecks.
- Intensified competition in the industry: The rapid development of the new energy vehicle market in recent years has attracted a large amount of capital into the new energy industry, ultimately leading to an increase in the number of thermal ball companies in the aluminum industry. Traditional powder production companies are also diversifying and gradually increasing or expanding their spherical alumina production capacity. Enterprises such as Denhua and Anhui Yishitong have many new production capacity projects, rapid growth in production capacity, increased product supply, and intensified product price competition.
Industry development opportunities:
Industry development opportunities are mainly reflected in three aspects:
- Policy support
- Breakthroughs in higher thermal conductivity and high filling technology
- The promotion of downstream demand
Global core manufacturers are mainly located in Japan, South Korea and China. In terms of output value, Japan and China account for more than 80% of the market share.
