Global Silicon Carbide and Ferrosilicon Industries Navigate Technological Shifts and Market Dynamics

Silicon Carbide: Innovation and Collaboration Drive Progress

The silicon carbide industry is witnessing accelerated innovation, particularly in the automotive and technology sectors. Recently, XPeng Motors and ICSI Integrated announced the mass production of China’s first hybrid silicon carbide product. This breakthrough combines silicon and SiC technologies to enhance performance while reducing costs, addressing a key barrier to broader adoption in electric vehicles (EVs). The hybrid solution maintains high efficiency and power density, paving the way for wider use in next-generation EVs.

Concurrently, strategic collaborations are strengthening the SiC supply chain. Tianyue Advanced and Toshiba Electronic Devices & Storage Corporation have entered a technical and commercial partnership to enhance the quality and reliability of SiC substrates for power semiconductors. This collaboration aims to optimize SiC performance for applications in railways, servers, and automotive sectors.

Technological advancements are also expanding SiC’s applications. Beyond EVs, SiC is gaining traction in AI server power supplies, where it improves energy efficiency and thermal management in data centers. Tianyue Advanced, a top-three global SiC substrate manufacturer, has commercialized 8-inch substrates and introduced 12-inch variants, supporting higher-volume production for advanced devices.

Ferrosilicon: Weak Demand and Supply-Demand Imbalance

In contrast, the ferrosilicon market faces persistent challenges due to subdued demand from its primary downstream sector, steelmaking. Recent data indicates a weak supply-demand balance, with low procurement enthusiasm from steel plants. Production levels remain stable but are constrained by high inventory levels and cautious purchasing behavior.

Industrial activity in the ferrosilicon sector is muted, with no significant capacity expansions or resumptions reported. Downstream demand, particularly from the metal magnesium market, remains weak, contributing to a sluggish outlook for the sector.

Geopolitical and Trade Dynamics

Trade policies continue to influence both industries. The U.S. inclusion of silicon in its 2025 Draft List of Critical Minerals highlights its strategic importance, likely accelerating domestic investment and supply chain resilience efforts. Additionally, tariffs on Chinese silicone products have prompted companies like Chenguang New Materials to establish overseas bases in Southeast Asia, diversifying supply chains to mitigate trade risks.

Future Outlook

The SiC industry is poised for robust growth, fueled by demand from EVs, AI infrastructure, and renewable energy projects. Hybrid SiC technologies and larger substrate sizes (e.g., 8-inch and 12-inch wafers) are expected to reduce costs and drive adoption. Conversely, the ferrosilicon market may continue to face headwinds until steel demand recovers significantly.

The silicon carbide and ferrosilicon industries are navigating distinct paths. SiC thrives on innovation and collaboration, while ferrosilicon contends with cyclical demand challenges. Strategic focus on high-value applications, supply chain resilience, and sustainability will be critical for long-term competitiveness. As technological advancements accelerate, both sectors are evolving to meet the demands of a rapidly changing global economy.
