Explore our core high-purity ceramic components, grinding media, and structural substrates engineered for extreme environments.
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 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.
Vertical Integration Advantage: By capturing the full lifecycle from nano-powder synthesis and Cold Isostatic Pressing (CIP) to 5-axis CNC diamond grinding, we guarantee sub-micron geometric tolerances and batch-to-batch consistency for critical mission applications.
As modern engineering pushes structural metals to their absolute physical limits, advanced technical ceramics have transitioned from alternative options to indispensable core components.
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.

From extreme insulation (Aluminum Titanate) to exceptional dissipation (Aluminum Nitride), our ceramics solve thermal dissipation challenges in high-frequency power electronics and jet propulsion.
Zirconia and Silicon Nitride components outlast hardened tool steel by 10 to 50 times in erosive slurry pumping, chemical metering, and ultra-fine pigment dispersion.
Zero magnetic interference and high dielectric breakdown strength enable reliable performance in 5G wireless telecommunications and high-power RF radar systems.
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.
At present, the company's products are sold well across the country and exported to Italy, the United Kingdom, Australia, Japan, Malaysia, Thailand, Hungary and other countries and regions. Committed to delivering high-quality products at reasonable prices, Qiangguang sincerely looks forward to establishing long-term and stable cooperative relations with global partners.
All products fully conform to EU REACH and RoHS directives. Food-grade ceramic components satisfy FDA and LFGB chemical safety standards, guaranteeing zero heavy metal leaching in medical dosing or food contact setups.
Developing next-generation Stereolithography (SLA) ceramic 3D printing technologies to produce complex internal cooling channels within alumina and silicon nitride parts without dedicated hard tooling.
Through sub-micron powder synthesis, our R&D team achieves average grain sizes below 200nm, resulting in superior flexural strength, higher fracture toughness, and glass-like mirror surface finishes (Ra < 0.02μm).
Review technical media powders, engineering components, and specialized structural ceramics directly available for factory-direct wholesale order.
When sourcing technical ceramics from China’s manufacturing base, procurement officers and engineering directors must evaluate beyond initial unit piece pricing. The total cost of ownership (TCO) in critical wear components and high-temperature environments depends heavily on chemical purity, grain size homogeneity, internal micro-crack density, and tight dimensional control.
In Zirconia ceramics ($ZrO_2$), pristine phase transformation relies on exact percentages of stabilizing oxides ($Y_2O_3$, $CeO_2$, or $MgO$). Inadequate dispersion of yttria leads to premature phase transition from tetragonal to monoclinic structure, causing micro-fractures under mechanical stress. Qiangguang utilizes wet-chemical co-precipitation to ensure uniform stabilizer distribution at the molecular scale.
For fluid sealing, dosing plungers, and grinding media applications, surface finish directly determines seal longevity and energy transfer efficiency. Our internal precision diamond polishing shop yields surface finishes down to $Ra < 0.05\ \mu\text{m}$, reducing friction coefficients against mating metal alloys to less than 0.1.
Whether your project requires 5 prototype samples for thermal testing or 500,000 units of grinding media per month, Yixing Qiangguang provides flexible cold press tooling, green machining, and high-capacity continuous tunnel kilns to transition seamlessly from R&D to mass assembly line supply.
