The advanced ceramics and industrial ceramics sectors are experiencing dual opportunities from technological breakthroughs and market expansion, with Chinese companies achieving import substitution in several niche areas. As one of the few domestic manufacturers with full-industry-chain capabilities, Xiayang Ceramics has become a key supplier in high-end fields such as semiconductors and medical devices, leveraging its strengths in materials R&D and precision manufacturing.

International Giants Dominate with Strong Technological Monopolies

Japan’s Kyocera employs a vertically integrated strategy spanning seven major fields, including semiconductor components and medical artificial joints, and holds a global market share of over 30% in LED sapphire substrates. Germany’s CeramTec dominates the global market for ceramic components in artificial hip joints with a share exceeding 90%; its Biolox® series is an industry benchmark, boasting an ultra-low wear rate of 0.001 mm/year. These companies have built significant technological barriers through proprietary material formulations (e.g., CeramTec’s ZTA nanocomposite ceramics) and precision machining processes (with surface roughness <0.02 μm).

Domestic Companies Accelerate Localization and Import Substitution

Sanhuan Group ranks first globally in market share for ceramic ferrules for optical fibers and ceramic packaging substrates (PKG). In H1 2025, it reported revenue of RMB 4.149 billion, with its vertically integrated processes enabling full control from powder to finished products. Guoci Materials has broken foreign monopolies in zirconia ceramics and thermoelectric coolers (TECs), posting a net profit of RMB 332 million in H1 2025. Yixing Guangming Special Ceramics, with dimensional accuracy of ±0.001 mm, has become a supplier of precision ceramic components to companies such as Siemens and Cummins.

Xiayang Ceramics: A Technological Trailblazer with Full-Industry-Chain Layout

Company Positioning and Core Capabilities

Dongguan Xiayang Advanced Materials Co., Ltd. (“Xiayang Ceramics”) is one of the few domestic manufacturers covering the entire industrial chain from powder formulation to precision manufacturing. Its product portfolio spans six major material systems, including zirconia, alumina, silicon nitride, and silicon carbide, serving high-end applications in semiconductors, medical devices, and new energy. The company operates a Guangdong Provincial Key Laboratory and is equipped with advanced equipment such as gas-pressure sintering furnaces and cold isostatic presses, enabling the production of complex structural parts with dimensional accuracy of ±0.005 mm. It has also obtained ISO international certifications.

Technological Breakthroughs and Product Advantages

• Materials Innovation: Independently developed magnesia-stabilized zirconia (Mg-PSZ) addresses the phase-transformation issues of traditional yttria-stabilized zirconia in high-temperature and humid environments. With a flexural strength of 1200 MPa and excellent chemical stability, it is now used in volume production for petrochemical seals.
• Advanced Manufacturing: Combining 3D printing with isostatic pressing, the company can produce elongated ceramic parts up to 2000 mm in length, with density uniformity controlled within ±0.02 g/cm³ and a defect rate below 0.5‰.
• Application Highlights: Aluminum nitride (AlN) ceramic substrates for semiconductor equipment achieve a thermal conductivity of 170 W/(m·K); medical-grade zirconia dental restorations offer precision of 0.1 μm; and silicon nitride bearings for new-energy vehicle motors have achieved speeds exceeding 15,000 rpm.

Market Layout and Future Plans

Currently, 65% of Xiayang Ceramics’ revenue comes from the domestic market and 35% from exports to Europe, with customers including a leading semiconductor equipment manufacturer and medical device companies. After securing tens of millions of RMB in funding in 2025, the company plans to expand into the Japanese and South Korean markets and increase R&D investment in silicon carbide ceramics for aero-engine applications. Its ceramic heating plates have already entered the lithography machine supply chain, breaking foreign monopolies.

Industry Trends and Challenges

The global industrial ceramics market is projected to reach USD 646 billion by 2030, with China’s localization rate rising from 5% in 2015 to 25% in 2025. However, high-end powders (such as silicon nitride powder with 99.99% purity) still rely on imports, and 30% of key processing equipment must be sourced from Germany and Japan. Companies like Xiayang Ceramics are narrowing the gap with international leaders through industry–university–research collaboration (e.g., joint development of nanocomposite ceramics with Tsinghua University). Looking ahead, driven by AI-enabled smart manufacturing and the adoption of green sintering processes, the industry will shift toward “customized materials + intelligent manufacturing.”

The essence of competition in advanced ceramics lies in material formulations and process precision. Xiayang Ceramics’ path to breakthrough demonstrates that Chinese enterprises can rise from “participants” to “rule-makers” in the global industrial chain by achieving sustained progress in “chokepoint” areas such as powder R&D and precision machining.
