Explore our factory-direct wholesale offerings engineering-grade zircon, zirconia, alumina, and nitrides engineered for extreme mechanical and thermal resistance.
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.
The company stands out as a rare domestic manufacturer engaged in the R&D, production, and supply of a comprehensive portfolio of technical ceramic materials. Our advanced material product range covers zirconia (ZrO₂), yttria (Y₂O₃), alumina (Al₂O₃), magnesia (MgO), aluminum nitride (AlN), boron nitride (BN), silicon nitride (Si₃N₄), silicon carbide (SiC), aluminum titanate (Al₂TiO₅), and other key synthetic ceramic materials engineered specifically for severe industrial environments.
Adhering to the core principle of "creating value for customers", Qiangguang provides customized and cost-efficient advanced ceramic solutions tailored to specific engineering demands.
Exporting across Italy, the United Kingdom, Australia, Japan, Malaysia, Thailand, Hungary, and North America under strict quality tracking system.
Understanding phase transformation dynamics, stabilizing dopants, and microstructural toughening mechanisms driving industrial reliability.
Pure Zirconium Dioxide ($\text{ZrO}_2$) undergoes crystal structure phase transitions upon heating: Monoclinic ($m$) at room temperature up to 1170°C, Tetragonal ($t$) from 1170°C to 2370°C, and Cubic ($c$) above 2370°C. The transition from tetragonal to monoclinic during cooling entails a volume expansion of approximately 3% to 5%. By introducing stabilizing oxides ($\text{Y}_2\text{O}_3$, $\text{MgO}$, $\text{CaO}$, $\text{CeO}_2$), the metastable tetragonal phase can be retained at room temperature. When a micro-crack propagates through the material, stress induces the $t \rightarrow m$ phase transformation, causing volumetric expansion that compresses the crack tip and arrests catastrophic brittle fracture.
Doped with 3 mol% $\text{Y}_2\text{O}_3$ (3Y-TZP), this material achieves sub-micron grain sizes (<0.5 µm) with unmatched flexural strength exceeding 1,200 MPa and fracture toughness ($K_{IC}$) up to 9-13 $\text{MPa}\cdot\text{m}^{1/2}$. Y-TZP provides maximum wear resistance, high density (>6.05 $\text{g/cm}^3$), and exceptional surface finish capabilities (Ra < 0.01 µm), rendering it the ultimate selection for ceramic cutting blades, wire-drawing dies, precision plunger pumps, and orthopedic implants.
Mg-PSZ (8-10 mol% MgO) and CSZ feature a multiphase microstructure consisting of tetragonal precipitates within a cubic matrix. Mg-PSZ exhibits superior resistance to thermal shock and low-temperature degradation (hydrothermal aging in moisture at 100°C - 300°C) compared to Y-TZP. This thermal stability makes Mg-PSZ ideal for molten metal handling, metallurgical nozzles, structural valves, and high-shock thermal applications.

Deploying advanced ceramics across harsh operation environments where metals, polymers, and traditional refractories experience premature structural breakdown.
High-purity AlN and YSZ substrates provide exceptional electrical insulation ($>10^{14}\ \Omega\cdot\text{cm}$), ultra-low dielectric loss, and high thermal conductivity required for wafer chucks, plasma etch resistance rings, LED heat sinks, and high-power laser diode carriers.
Biocompatible Y-TZP and alumina-toughened zirconia (ATZ) are certified for long-term surgical implants, femoral head prostheses, dental crowns, and endoscopic surgical tools due to zero chemical cytotoxicity, high fatigue strength, and extreme wear immunity.
In EV battery management systems and silicon carbide (SiC) power modules, technical ceramic insulating spacers, seal rings, and cooling plates handle high voltages, rapid thermal cycling, and aggressive chemical coolants without mechanical failure.
Zirconia plunger shafts, mechanical face seals, valve balls, and slurry spray nozzles resist cavitation erosion, aggressive acid/alkali corrosion (pH 0-14), and continuous abrasive particle impact in oilfield exploration and chemical refinement lines.
Benefiting from excellent product performance and stable quality, Qiangguang’s ceramic products are extensively utilized in high-end fields such as food and medical processing, new energy vehicles, laser semiconductors, petrochemical engineering, powder metallurgy, national defense, and aerospace sectors.
Leveraging domestic raw material integration, high-capacity automated sintering kilns, and global export logistics.
China holds world-leading reserves and processing facilities for zircon sand ($\text{ZrSiO}_4$), rare-earth stabilizers ($\text{Y}_2\text{O}_3$, $\text{CeO}_2$), and high-purity alumina powders. Qiangguang maintains strategic long-term supply agreements, guaranteeing batch-to-batch chemical purity, minimal trace impurities ($\text{Fe}_2\text{O}_3 < 100\ \text{ppm}$), and stable pricing resilience against global market fluctuations.
Our Yixing production complex operates automated spray drying towers, continuous electric tunnel kilns, and high-temperature shuttle kilns capable of sustained firing up to 1,800°C under controlled atmospheric conditions (Air, Vacuum, $\text{N}_2$, $\text{Ar}$, $\text{H}_2$). Digital PID control loops ensure tight temperature uniformity within $\pm2^\circ\text{C}$ throughout the thermal profile.
By consolidating synthesis, green-body forming, sintering, precision diamond machining, and quality inspection under one roof, Qiangguang eliminates intermediary markups.
