Global Spherical Alumina Filler Market Growth 2025-2031

Global Spherical Alumina Filler Market Growth 2025-2031

The global Spherical Alumina Filler market size is predicted to grow from US$ 423 million in 2025 to US$ 742 million in 2031; it is expected to grow at a CAGR of 9.8% from 2025 to 2031.

Spherical alumina is a thermally conductive functional filler made of industrial alumina powder as raw material through multiple processes such as purification, dynamic combustion into balls, precision classification, surface modification, compounding, and homogenization. The physical and chemical properties of alumina powder are stable, strong adsorption capacity, high hardness, and the spherical structure makes it have a larger specific surface area and better fluidity.

Spherical alumina preparation process:

1. Ball milling method (high energy ball milling)

Ball milling is the most common method for preparing plagiarized alumina powder. The ball mill itself is a horizontal type, with a built-in steel ball grinding medium, so that after the material enters the cylinder, it will collide with the steel ball to produce an impact force to achieve a crushing effect. Adding grinding aids in the ball milling process can improve the uniformity of powder particle size.

2. Polymer network sol-gel method

Advantages: small particle size; disadvantages: poor sphericity

Global key players of Spherical Alumina Filler include Denka, Admatechs and Bestry Technology, etc. The top three players hold a share over 60%. Asia-Pacific is the largest market, has a share about 65%. In terms of particle size, 30-80μm is the largest segment, occupied for a share of about 45%, and in terms of application, Thermal Interface Materials has a share about 50 percent.
