Alumina 99 Porcelain Ceramic Plate

Industrial Ceramic Plate   Alumina 99 Porcelain Ceramic Plate   High-purity ceramic alumina sheets (aluminum oxide, Al2O3) have a high melting point, high hardness, and excellent chemical stability. They maintain high hardness and strength even at high temperatures. They also possess unique properties, such as excellent electrical insulation, high chemical resistance, good wear and heat resistance, and low thermal expansion. Alumina sheets are widely used for calcining and sintering in furnaces, metallurgy, the automotive industry, and the chemical industry.     Advantages 1. High-Temperature Resistance: Alumina ceramic substrates can withstand temperatures up to 1600°C (Al₂O₃ ≥ 99%) for extended periods. 2. High Electrical Insulation: Alumina ceramic substrates have a dielectric constant of 10, making them suitable for use as insulators in high-voltage applications. 3. Low Thermal Expansion: Alumina ceramic substrates have a low coefficient of thermal expansion, making them suitabl…
