Spherical alumina has a wide range of applications. my country is the world’s leading producer.

Spherical alumina refers to an alumina powder material generated from ordinary irregular-shaped alumina (Al2O3) through high-temperature melt spraying, calcination, screening, purification and other processes. Spherical alumina has the advantages of high sphericity, high thermal conductivity, good fluidity, excellent insulation, good continuous stability, strong corrosion resistance, good high temperature resistance, and controllable particle size distribution. It is widely used in thermal interface materials (thermal conductive materials). ), thermally conductive engineering plastics, surface protective coatings, optical materials, semiconductor materials, catalysts and other fields have broad application prospects.

Depending on the particle size of the product, spherical alumina can be divided into ordinary spherical alumina and nanoscale spherical alumina. Among them, ordinary spherical alumina is mainly used in the fields of thermally conductive engineering plastics, surface protective coatings, thermal interface materials, catalysts, etc. End products include thermally conductive paste, thermally conductive gel, thermally conductive gaskets, metal surface protective coatings, etc. With the current trend of integration and miniaturization of consumer electronic equipment rising, the demand for thermally conductive materials continues to increase, and as a key filler for thermally conductive materials, the demand for spherical alumina continues to grow.

Nanoscale spherical alumina is mainly used in the fields of optical materials and semiconductor materials. Specifically, it can be sintered into transparent ceramics as luminescent materials for high-pressure sodium lamps, and can be combined with rare earth phosphors as luminescent materials for oral light lamps. Substrate materials for large-scale integrated circuits and production scenarios of various sensor materials. Spherical alumina has a wide range of applications, and its market size is currently expanding amid the rapid development of the downstream market. According to the“2023-2028 Spherical Alumina Industry Market In-depth Research and Investment Prospects Forecast Analysis Report” released by the Industrial Research Center It shows that the global spherical alumina market size will reach US$260 million in 2022, a year-on-year increase of 9.3%.

Globally, the companies that are developing the spherical alumina market mainly include international companies such as Sanyo of Japan, Inframat of the United States, Beggs of the United States, and Showa Denko of Japan, as well as Ya’an Baitu High-tech Materials, China Aluminum Corporation of China, Chinalco Shandong, and Tianjin Zexi Minerals. Processing, Jiangsu Lirui New Materials, Henan Tianma New Materials, Jiangsu Jingxin New Materials, Zibo Venus New Materials, Luoyang Super League New Materials and other Chinese companies.
