Explore our premium grade ceramic powders, precision-machined structural parts, and thermal management solutions designed for operations exceeding 1700°C.
Founded in 2003, Yixing Qiangguang Ceramic Materials Co., Ltd. is a premier high-tech enterprise dedicated to the research, development, precision manufacturing, and system integration of high-performance technical ceramic materials. As one of the few fully integrated manufacturers in China, our supply capabilities encompass the entire industrial chain—from high-purity ceramic powder synthesis and green body forming to high-temperature sintering, sub-micron precision machining, and tailored engineering application solutions.
Our comprehensive portfolio covers extreme temperature resistant and structurally resilient ceramic materials including Yttria-Stabilized Zirconia (YSZ), Alumina (Al₂O₃), Magnesia (MgO), Aluminum Nitride (AlN), Silicon Nitride (Si₃N₄), Boron Nitride (BN), Silicon Carbide (SiC), and Aluminum Titanate (Al₂TiO₅).
Analyzing thermal stability, phase transformation, and structural integrity across harsh operating regimes.
Modern thermal processing requires advanced technical ceramics capable of resisting temperatures above 1600°C up to 2400°C without mechanical degradation, oxidation, or structural creep. Materials like YSZ and Magnesium Oxide provide the backbone for ultra-high temperature furnaces and thermal barrier coatings (TBCs).
With sub-3nm chip fabrication, plasma erosion resistance and thermal dissipation become paramount. Aluminum Nitride (AlN) delivers high thermal conductivity (>170-200 W/m·K) matched with CTE closely aligned with Silicon, eliminating thermal fatigue in electrostatic chucks (ESC) and wafer heaters.
In metallurgy and foundry applications, thermal shock coupled with chemical corrosion causes rapid failure of standard refractories. Aluminium Titanate (Al₂TiO₅) features near-zero thermal expansion, preventing cracking during rapid quenching in low-pressure aluminum casting risers and dosing tubes.

Adhering to our core philosophy of "Creating Measurable Value for Customers", Qiangguang delivers tailored, cost-efficient ceramic solutions optimized for demanding environmental stress. Supported by rigorous quality control protocols and complete batch traceability, we streamline purchasing and operational efficiency for OEM clients worldwide.
Our products serve leading industrial enterprises in over 20 nations, including Italy, the United Kingdom, Australia, Japan, Malaysia, Thailand, Hungary, Germany, and the United States. From aerospace propulsion systems to high-end medical diagnostic equipment, our ceramic engineering ensures uncompromised structural reliability.
By mastering powder synthesis through cold isostatic pressing (CIP) and diamond CNC grinding, we maintain strict phase purity control and tight dimension tolerance (up to ±0.001mm).
Addressing thermal shock resistance, additive manufacturing of ceramics, and microstructural phase control.
Stereolithography (SLA) and Selective Laser Sintering (SLS) are revolutionizing ceramic component design. We are pioneering complex internal cooling channel integration within YSZ and Si₃N₄ parts, allowing active thermal management in gas turbine blades and rocket nozzles previously unachievable through traditional slip casting.
By controlling yttria dopant concentration (typically 3mol% for tetragonal stability and 8mol% for cubic ionic conductivity), our YSZ formulations leverage stress-induced phase transformation (tetragonal to monoclinic). This mechanism arrests crack propagation under severe thermal shocks during high-frequency heating cycles.
Eliminating silica grain boundary impurities in Alumina and Aluminum Nitride components increases thermal breakdown voltage and prevents lattice phonon scattering. Our cleanroom atmosphere vacuum sintering ensures AlN achieves consistent thermal conductivity exceeding 200 W/m·K.
Whether engineering thermal barriers for space vehicle re-entry, non-magnetic insulating housings for high-field MRI units, or thermal management substrates for 800V Electric Vehicle (EV) silicon carbide (SiC) inverters, Qiangguang provides turnkey material co-development. We assist enterprise buyers from finite element thermal analysis (FEA) material selection through rapid prototyping to full-scale automated factory manufacturing.
