Polycrystalline Alumina (PCA) represents the pinnacle of ceramic engineering, balancing optical translucency with extreme mechanical robustness. At Shanghai Creative Advanced Materials Co., Ltd (SCA), we define PCA as a multi-crystalline structure composed of alpha-alumina grains with a purity exceeding 99.9%. Unlike standard industrial ceramics, our Polycrystalline Alumina is engineered to eliminate light-scattering pores, making it essential for high-intensity discharge lamps and semiconductor lithography equipment.
Our factory employs specialized dopants like Magnesia (MgO) to inhibit abnormal grain growth during sintering, ensuring a uniform microstructure that withstands thermal shocks up to 1600°C.
With an extremely low loss tangent and high dielectric strength, our PCA components serve as critical insulators in high-frequency vacuum electronics and microwave processing.
PCA is virtually impervious to molten alkali metals and halogen gases, making it the material of choice for chemical vapor deposition (CVD) chambers and corrosive fluid handling.

In an era of global supply chain volatility, SCA's Shanghai Industrial Development Zone facility serves as a beacon of reliability. We integrate Industry 4.0 principles to ensure that every polycrystalline alumina supplier agreement we sign is backed by data-driven manufacturing.
Every alumina target and ceramic component is assigned a unique serial number, providing a full digital record from raw powder batch to the final 3D CMM inspection report.
We utilize automated Isostatic Pressing (CIP) and Hot Press Sintering (HP) to eliminate human error, ensuring consistent density and zero-defect structural integrity.
Our next-gen sintering furnaces reduce energy consumption by 25% while maintaining the precise vacuum levels required for high-purity PCA production.
Polycrystalline Alumina is used in wafer processing chambers, providing erosion resistance against fluorine-based plasmas. Our PCA targets ensure ultra-high purity thin-film deposition.
From infrared-transparent radomes to armor plating for helicopters, PCA's hardness (second only to diamond/B4C) provides mission-critical protection and performance.
As a key supplier of boron carbide and europium oxide neutron absorbers, SCA integrates PCA as structural cladding for its radiation stability and thermal conductivity.
The biocompatibility of high-purity Al2O3 makes PCA an ideal candidate for prosthetic implants and dental aesthetics, where light transmission mimics natural enamel.
The future of advanced ceramics lies in the convergence of material science and digital fabrication. Shanghai Creative Advanced Materials is currently investing in three core future-tech pillars:
Navigating international trade in advanced materials requires more than just a good product. SCA provides a robust framework for global procurement:
Fully compliant with EU environmental directives.
Expert handling of sensitive material export regulations.
Technical teams available for integration in EU, USA, and SE Asia.
Certified quality management across all production lines.
As detailed in our production flow control, we manage every step with precision:
We control purity, particle size, and chemical composition stability to ensure the foundation of every Polycrystalline Alumina component is flawless.
Our facility is equipped for hot pressing sintering, pressureless sintering, reaction sintering, and isostatic pressing sintering.
Equipped with CMM size testing, ceramic performance testing, and powder performance testing to guarantee absolute accuracy.
Established in Shanghai Industrial Comprehensive Development Zone, SCA is a high-tech company integrating research, development, production, and sales. We specialize in semiconductor ceramic targets, powder metallurgy targets, and high-performance ceramic components like Boron Carbide (B4C), Silicon Carbide (SiC), and Alumina (Al2O3).
Monocrystalline Alumina (Sapphire) is a single crystal, while PCA consists of many small crystals. PCA offers more versatility in shape forming and is more cost-effective for large industrial components while maintaining similar thermal and chemical properties.
Yes, we specialize in professional design and high-precision machining. We can customize solutions with unique geometries to meet specific application requirements in semiconductors and aerospace.
With our efficient Factory 4.0 production lines and several logistics partners, we offer fast delivery. Standard orders typically ship within 4-6 weeks, depending on complexity.
We perform rigorous testing of raw powders and utilize clean-room packaging (dust-free workshops) to ensure that the products are not contaminated during the packaging process.
