The aluminum nitride market is undergoing significant change. On the supply side, a major Japanese player holds approximately 75% of the global high-purity aluminum nitride powder market share, yet its annual capacity remains only about 850 tons with conservative expansion plans. Although domestic Chinese producers are catching up rapidly, the supply-demand gap remains substantial, keeping import aluminum nitride powder price at approximately RMB 1,400/kg. This shortfall is precisely the core driver for import substitution.
(The right figure is based on publicly available industry data, reflecting the trend of a widening supply-demand gap. Data are illustrative and for reference only.)
Five drivers accelerating localization:
1. Supply chain security. Tighter export controls on high-purity powders have made self-sufficiency in aluminum nitride powder an urgent priority for downstream customers.
2. Cost advantage. Domestic aluminum nitride powder suppliers are approaching international quality standards while reducing production costs by approximately 20%, significantly accelerating the substitution process.
3. Policy support. Aluminum nitride has been included on China's "bottleneck" materials list, with strong backing from national and local government funds.
4. Surging demand. The proliferation of 800V platforms in new energy vehicles is boosting cooling requirements for SiC modules, while rising GPU power consumption in AI servers further drives the market. Both trends are fueling exponential demand growth for AlN ceramics and aluminum nitride sheet, making them one of the fastest-growing segments in the high-end ceramic electronic substrate market.
5. Technology catch-up. Domestic manufacturers are improving rapidly, with some products achieving thermal conductivity approaching 230–250 W/(m·K), matching international advanced levels.
The aluminum nitride market is currently at a critical inflection point defined by a "surge in demand × domestic filling." Although import aluminum nitride powder prices will remain elevated in the near term, local players with integrated capabilities—spanning from powder synthesis to the precision machining of aluminum nitride ceramic for optical modules—are set to capture the majority of the value pool.
By 2025, the global market for aluminum nitride components in optical communications is projected to reach tens of billions of RMB, yet the current localization rate remains low. The window for import substitution of aluminum nitride ceramic for optical modules is now fully open.
