Thermal properties include a thermal conductivity of 33.0 W/m K and a coefficient of thermal expansion of 8.2 x 10^-6/¬8C, which are critical for applications involving temperature fluctuations. The dielectric strength is rated at 8.7 kV/mm, indicating excellent electrical insulation capabilities, while the volume resistivity exceeds 10^14 ohm-cm at room temperature, ensuring minimal electrical leakage. PlasmaPure-UC,Ñ¢ is manufactured using various advanced processes, including injection molding and isostatic pressing, allowing for precise component fabrication. This product is ideal for engineers seeking high-performance ceramics for specialized applications in electronics, wear-resistant components, and other technical fields.
Aluminas (aluminum oxide, Al2O3) are the most commonly used technical ceramics due to their generally useful properties and good price/performance ratio. Alumina ceramics are commonly subdivided according to their alumina content ranging from 80% to more than 99%. Higher purity alumina demonstrates enhanced wear and corrosion resistance — creating a continuous scale of various alumina grades, compositions, and performance.
Aluminas are used in both general use and specialized applications. A grade is selected to fit the application environment. Alumina compositions and microstructures can be formulated to meet the specific performance requirements of more demanding applications.
