Explore our precision-formulated advanced ceramic materials engineered for severe industrial environments, extreme temperatures, and high chemical exposure.
Advanced technical ceramics represent the cornerstone of next-generation engineering applications. In comparison to traditional metals and polymers, ceramic materials offer exceptional thermal stability, extreme hardness, chemical inertness, superior dielectric properties, and high mechanical strength under extreme environments. Achieving optimal material density and near-net-shape geometries requires mastery over specific ceramic casting processes including Slip Casting, Gel Casting, Tape Casting, Low-Pressure Injection Molding, and Isostatic Pressing.
As global high-tech industries—such as semiconductor fabrication, aerospace propulsion, medical bio-implants, and electric vehicles—demand increasingly complex structural ceramic components, China has emerged as the premier manufacturing hub for advanced ceramic casting and precision thermal sintering. Mastering the microstructural evolution during casting is critical: slurry rheology, binder burnout phase control, green body density uniformity, and microstructural phase transformations directly govern final physical performance.
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 raw powder synthesis, slurry slip preparation, precision green body forming, vacuum sintering, and CNC diamond machining to integrated end-user engineering solutions.
The company is a rare domestic manufacturer equipped with the scientific capability to supply a comprehensive portfolio of oxide and non-oxide technical ceramic materials. Our product range encompasses Yttria-Stabilized Zirconia (YSZ), Magnesia-Stabilized Zirconia (MSZ), High-Purity Alumina (Al2O3), Magnesium Oxide (MgO), Aluminum Nitride (AlN), Boron Nitride (BN), Silicon Nitride (Si3N4), Silicon Carbide (SiC), Aluminum Titanate (Al2TiO5), and customized electro-ceramic formulations.
In-house control over chemical synthesis, spray drying, slip casting molds, high-pressure sintering, and ultrasonic grinding ensures total quality repeatability and material traceability.
Tailored material formulations engineered for specific thermal expansion coefficients (CTE), electrical isolation thresholds, fracture toughness, and wear profiles.
Full compliance with ISO 9001:2015, stringent batch testing via X-ray diffraction (XRD), scanning electron microscopy (SEM), and CMM coordinate dimensional analysis.
Choosing the correct ceramic composition and casting methodology relies on understanding material behavior under high stress, chemical attack, and extreme thermal gradients.

The execution of advanced ceramic casting requires exact control over colloidal chemistry, rheological additives, binder chemistry, and thermal debinding profiles. At Yixing Qiangguang Ceramic Materials Co., Ltd., we utilize five primary casting & forming methodologies tailored to specific product geometries and performance demands:
Fluid DynamicsComplex Hollow Forms
Slip casting involves pouring a high-solids aqueous ceramic slurry into a porous plaster or synthetic mold. Capillary pressure draws liquid out of the suspension, consolidating a uniform ceramic shell along the internal mold wall.
High Green StrengthNear-Net Shape
Gel casting combines ceramic powder slurry with organic monomers. Upon adding a catalyst and initiator, the slurry undergoes in-situ polymerization, crosslinking into a solid, highly uniform hydrogel matrix inside a non-porous mold.
Thin SubstratesMicro-Electronics
A controlled reservoir of ceramic slurry is metered onto a moving carrier film using an ultra-precise doctor blade, producing flexible, ultra-thin ceramic sheets upon solvent evaporation.
High-Volume Complex PartsUltra-Dense
CIM mixes thermoplastic binders with ceramic powders for high-pressure multi-cavity injection molding. For massive structural items, Cold Isostatic Pressing (CIP) applies uniform fluid pressure up to 300 MPa.
Benefiting from superior physical stability, wear resistance, electrical isolation, and biocompatibility, Yixing Qiangguang's cast ceramics serve multi-sector industrial systems globally:
Silicon Nitride gas rings, high-purity alumina end-effectors, optical laser cavities, wafer chucks, and chemical vapor deposition (CVD) carriers.
Biocompatible zirconia surgical blades, dental blanks, dosing pistons, food-contact filling pumps requiring ultra-smooth finishes (Ra < 0.05 μm).
High-voltage relay insulation covers, ceramic thermal barriers for EV battery packs, drive motor shaft bearings, fuel cell stack components.
Magnesia and YSZ crucibles, aluminum titanate low-pressure casting riser tubes, desulfurization spray nozzles, and severe slurry pump liners.
At present, Yixing Qiangguang Ceramic Materials Co., Ltd.'s engineered components are sold extensively across China and exported to key international industrial markets including Italy, the United Kingdom, Australia, Japan, Malaysia, Thailand, Hungary, North America, and Western Europe.
Committed to delivering high-quality products at competitive manufacturer-direct pricing, Qiangguang fosters long-term strategic alliances with global tier-1 equipment builders, research institutions, and industrial distributors.
As industrial processing environments trend toward higher operating temperatures, harsher chemical corrosion, and micro-scale precision, Yixing Qiangguang is continuously advancing its R&D roadmap:
Integrating stereolithography (SLA) 3D ceramic printing with traditional slip and gel casting to produce non-traditional internal cooling channels without expensive tooling.
Developing multi-phase Zirconia-Toughened Alumina (ZTA) and Silicon Nitride-Silicon Carbide nanocomposite powders for extreme shock and wear environments.
