The material of ceramic reflector is 99% Al2O3.Its green body is fired at a suitable temperature to retain the proper porosity and strength. The surface of the ceramic reflector is coated with a high reflectivity ceramic glaze ,so compared with the gold-plated reflector , its has long service life and diffuse reflection. Prime Features: - Surfaces can be sealed and coated with a solarization-resistant glaze to give high bulk refectivity - 98% reflectance efficiency at 600-1000nm - Reflectance efficiency exceeds 96% across the wavelength range 400-1200nm (see curve) - Controlled porosity, Good thermal conductivity, High electrical resistivity. Physical Characteristics: - Color: White - Density: 3.1Mg/m^3 - Porosity: 22% - Flexural strength: 170Mpa - Coefficient of thermal expansion: 7.9×10^-6--/С (200～500℃) 9×10^-6/С (200～1000℃)

High Hermeticity Metallized Ceramic Bushing Features: 1.Material: 96% Aluminia(AL2O3) 2.Coating Layer:Molybdenum-Mananese(Mo/Mn) 3.These metallized ceramics are ideal for high voltage, high vacuum and high pressure applicationos. So far the most widely-used and effective method for creating a leak-tight, robust joint between ceramic and metal is by brazing . A thin layer of metal deposited on a ceramic part enables brazing between ceramic and metal part that h as a different coefficient of thermal expansion. A layer of Molybdenum-Manganese is deposited with a typical thickness of 8 to 30 µm after sintering. The metallized surface receives a secondary coating of nickel to seal and improve wettability for later brazing. Applications: Electrical transmission and distribution Electronics industry Textile machinery Defense Medical electronics Automobile industry Sealing Solid Oxide Fuel Cells High temperature application
