Discover our high-precision zirconia, silicon nitride, and thermal management ceramic components manufactured under strict ISO quality controls.
The global technical ceramics market is experiencing a profound structural shift driven by modern semiconductor lithography, high-voltage vehicle electrification, aerospace thermal barrier innovation, and harsh chemical process engineering.
Industrial demand is escalating for components capable of enduring extreme mechanical stress, chemical corrosion, high dielectric voltage, and operating temperatures surpassing 1500°C without mechanical degradation.
Achieving sub-micron microstructural consistency is paramount. Nano-phase stabilization using Yttria (YSZ), Magnesia (MSZ), and Calcia (CSZ) ensures maximized fracture toughness and eliminates micro-fractures.
Aluminum Nitride (AlN) and Silicon Nitride (Si3N4) have become indispensable for high thermal conductivity substrates, heat sinks, and plasma-resistant wafer chucking systems in next-generation fabrication lines.
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.
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.
By leveraging controlled powder chemistry, cold isostatic pressing (CIP), high-temperature vacuum sintering, and multi-axis CNC diamond grinding, Qiangguang delivers ceramic components engineered to perform under ultra-demanding structural and thermal loads.
Selecting the optimal ceramic material requires evaluating thermal expansion, dielectric strength, fracture toughness, and chemical inertia.

With EV drivetrains pushing higher voltage architectures (800V+), silicon nitride hybrid bearings prevent electrical fluting while yttria-stabilized zirconia slurry grinding beads enable ultra-fine dispersion of cathode and anode nano-materials down to sub-100nm scales.
High-purity Aluminum Nitride (AlN) components provide exceptional dielectric breakdown strength combined with thermal conductivity approaching copper. Ideal for plasma etch ring components, electrostatic chucks (ESC), and wafer carrier plates.
Magnesium and Yttria-stabilized zirconia materials maintain phase stability under severe thermal shock cycles. Utilized for turbine blade coatings, rocket nozzle liners, and high-velocity friction pads operating above 1400°C.
Biocompatible Y-TZP ceramic plungers, check valves, and metering pumps ensure non-contaminating, zero-wear operation for dosing precise liquid pharmaceuticals and processing sterile medical fluids.
Severe service ball valves manufactured from high-toughness transformation-toughened zirconia withstand slurry abrasion, acid leaching, and sudden pressure drops that quickly erode metallic alloys.
Aluminium Titanate features low thermal expansion coefficient and outstanding non-wetting properties against molten aluminum alloys, extending the life of dosing tubes, sprue bushings, and casting nozzles.
