Founded in 2003, Yixing Qiangguang Ceramic Materials Co., Ltd. is a professional provider dedicated to the research and development (R&D), manufacturing, and application solutions of high-performance advanced ceramic materials. It is among the few enterprises in China that possess a complete industrial chain, covering key links from powder forming, sintering and precision machining to the provision of integrated application solutions.
As an industry-leading Wholesale Precision Limited Supplier, the organization addresses critical bottlenecks encountered in modern high-tech industries. By controlling every stage—from sub-micron chemical synthesis to sub-micron CNC machining—Qiangguang delivers unmatched reliability, dimensional consistency, and tailored material phase stability.
The company is also a rare domestic manufacturer engaged in the R&D, production, and supply of a comprehensive portfolio of ceramic materials. Its product range covers zirconia, yttria, alumina, magnesia, aluminum nitride, boron nitride, silicon nitride, silicon carbide, aluminum titanate and other key ceramic materials for industrial use.
Comprehensive mechanical, thermal, and electrical performance parameters for critical industrial decision-making.
Engineered for maximum fracture toughness and mechanical shock resistance. Silicon Nitride exhibits exceptional resistance to thermal shock, making it ideal for severe bearing environments, gas turbine components, and high-wear industrial nozzles.
Delivering ultra-high thermal conductivity (up to 180-230 W/m·K for AlN) paired with superior electrical isolation. Essential for substrate thermal management in semiconductor power modules, LED packaging, and high-frequency RF systems.
Utilizing tetragonal-to-monoclinic phase transformation toughening. Yttria, Ceria, Calcium, and Magnesium stabilized zirconia matrices yield high flexural strength (>1000 MPa) and extreme wear resistance for fine grinding applications.
Characterized by near-zero thermal expansion coefficient and low thermal conductivity. Highly resistant to non-ferrous molten metals, providing non-wetting properties for aluminum casting, riser tubes, and thermal barrier applications.

Serving mission-critical infrastructure across high-end industrial, chemical, and aerospace sectors.
Benefiting from excellent product performance and stable quality, its products are extensively utilized in various high-end fields, such as food and medical industries, new energy vehicles, laser semiconductors, petrochemical engineering, powder metallurgy, national defense and military, as well as aerospace sectors.
In modern industrial manufacturing, component failure under high abrasion, aggressive chemical exposure, or extreme thermal shock leads to costly operational downtime. By engaging with a trusted Wholesale Precision Limited Supplier, global OEMs secure customized microstructures that optimize component service lifespans by factors of 3x to 10x over conventional metallic alloys.
Systematic quality verification ensuring zero-defect manufacturing for high-reliability end-use components.
Utilizing high-purity chemical coprecipitation, spray drying, and calcination to maintain strict control over grain size distribution, phase composition, and purity levels up to 99.99%.
Uniform compaction under fluid pressures up to 200 MPa ensures homogeneous density distribution across complex geometry green bodies, preventing micro-warping during sintering.
High-temperature gas pressure sintering (GPS) and vacuum sintering furnaces operate at up to 2000°C to achieve full theoretical material density and eliminate residual microporosity.
5-axis CNC diamond grinding, ultrasonic milling, and laser surface finishing achieve Ra < 0.05 µm surface roughness and tight dimensional tolerances checked via CMM inspection.
Advancing structural ceramic capabilities through additive manufacturing, nano-composite grain boundaries, and eco-friendly processing.
As global industries transition toward electrification, higher power density semiconductors, and green hydrogen synthesis, demand for specialized ceramics is expanding exponentially. Yixing Qiangguang's long-term R&D strategy focuses on three key pillars:
1. Additive Manufacturing of Complex Ceramics (3D Printing): Overcoming traditional machining constraints by implementing stereolithography (SLA) and binder jetting for intricate internal cooling channels in turbine parts and semiconductor chucks.
2. Nano-Composite Materials: Integrating carbon nanotubes and silicon carbide whiskers into ceramic matrices to boost fracture toughness beyond 15 MPa·m1/2, closing the gap between ceramic temperature resistance and metallic impact toughness.
3. Zero-Carbon Sintering Technologies: Investing in rapid flash sintering and microwave-assisted sintering to reduce thermal processing energy footprints by up to 60% while inhibiting undesirable grain growth.
In-depth technical answers addressing procurement, material selection, and custom fabrication inquiries.
Adhering to the core principle of "creating value for customers", Qiangguang provides customized and cost-efficient advanced ceramic solutions tailored to the specific demands of different customers. It is supported by high-quality after-sales services and a strict full-process tracking system, which effectively enhances cooperation efficiency and promotes continuous quality improvement.
