As a leading China Translucent Alumina Manufacturer, Shanghai Creative Advanced Materials Co., Ltd. (SCA) understands that material science is the backbone of the next industrial revolution. Translucent Alumina, specifically Polycrystalline Alumina (PCA), is a high-performance ceramic that combines the chemical and mechanical properties of sapphire with the versatility of ceramic processing. With over 19 years of experience, our facility serves as a global hub for industries requiring 99.99% (4N) purity materials that offer exceptional light transmission and thermal stability.
The demand for translucent ceramics has shifted from simple lighting applications to complex semiconductor windows, medical dental brackets, and aerospace sensor protection. By leveraging advanced sintering technologies—such as vacuum sintering and hot isostatic pressing (HIP)—we provide an information gain that moves beyond standard commodity supply, offering true technical partnership.
In the semiconductor sector, translucent alumina is utilized for wafer processing components. Its resistance to plasma erosion and high-temperature stability makes it ideal for lift pins, focus rings, and viewing windows in etch chambers.
Our PCA ceramics are biocompatible and offer the refractive index necessary for aesthetic dental brackets. We provide sub-micron grain size control to ensure maximum transparency and mechanical strength.
Protecting sensitive infrared sensors requires materials that are hard yet transparent. Translucent Alumina provides a cost-effective alternative to single-crystal sapphire for missile domes and aircraft sensor housings.
The evolution of Translucent Alumina Factories in China is currently focused on three core technical pillars:
Moving from 4N (99.99%) to 5N (99.999%) purity to minimize light scattering centers. We control particle size distribution at the nanometer scale to ensure uniform sintering density.
Utilizing Hydrogen Atmosphere Sintering and Spark Plasma Sintering (SPS) to achieve theoretical density. This removes residual porosity, which is the primary enemy of transparency.
Post-sintering, materials are processed using imported high-precision equipment to reach Ra < 0.01μm surface finishes, essential for optical applications.
Our integrated production flow ensures every unit meets stringent semiconductor-grade standards.
We control purity, particle size, and chemical stability. Full record traceability is provided from raw powder to the final sintered component.
Slurry concentration and composition uniformity are monitored to ensure consistent loose tap density of the powder.
Using automated presses to form the green body, providing superior strength and consistency compared to manual processes.
Methods include hot pressing, pressureless, and isostatic pressing. For translucency, vacuum sintering is the core advantage.
High-precision imported equipment ensures product accuracy and micron-level tolerances for critical industrial parts.
Equipped with CMM size testing and ceramic performance testing to guarantee mechanical and optical properties.
SCA provides more than just manufacturing; we offer a Global Supply Chain Guarantee. As a registered high-tech enterprise in the Shanghai Industrial Comprehensive Development Zone, we adhere to international standards:
A: Our high-purity PCA can achieve a total light transmission (TLT) of up to 85% in the visible spectrum and over 90% in the infrared range, depending on thickness and surface polish.
A: We use dopants like MgO (Magnesium Oxide) in ppm levels to inhibit grain boundary migration, ensuring a fine-grained structure that maximizes strength and transparency.
A: Yes, our CNC diamond grinding capabilities allow us to produce complex discs, rings, and custom shapes with tolerances as tight as +/- 0.005mm.
A: Polycrystalline Alumina (PCA) is significantly more cost-effective for large-scale production and offers isotropic properties, meaning its strength and expansion are uniform in all directions.
