Product Name:
Wear-Resistant Alumina (99% / 96% Al₂O₃) Sintering Plate
Product Material:
High-purity alumina ceramic (Al₂O₃ 99%-99.8%), suitable for high-temperature sintering processes, reinforced with Zirconia Toughened Alumina (ZTA) for key friction or impact-prone areas to enhance mechanical strength and durability
Material Characteristics:
Extremely high hardness (Mohs 9), excellent wear resistance, superior thermal stability for high-temperature sintering, exceptional chemical corrosion resistance (resistant to acids, alkalis, molten salts), high dimensional stability with minimal shrinkage during firing, excellent electrical insulation, smooth surface finish (Ra < 0.05 µm), high material purity with no metal ion contamination
Application Fields:
Sintering cathodes and electrolytes in metallurgical and ceramic processes, high-temperature industrial sintering setups requiring wear-resistant plates, support plates or fixtures in chemical and electrochemical sintering operations
Application Industries:
Metallurgy and metal processing (cathode/electrolyte sintering), ceramic manufacturing (high-temperature firing and forming), chemical industry (corrosion-resistant high-temperature equipment), energy and battery manufacturing (electrolyte and electrode sintering processes)
Processing Difficulties:
Maintaining flatness and parallelism over large surface areas under high-temperature sintering, controlling shrinkage and dimensional tolerances for precise fit in high-temperature assemblies, achieving smooth defect-free surfaces that resist wear and prevent sticking of molten materials, ensuring structural integrity under repeated thermal cycling
Processing Flow:
Material selection and design, high-purity powder preparation and homogenization, uniaxial or isostatic pressing, controlled high-temperature sintering, precision grinding and lapping of critical surfaces, surface polishing and finishing, dimensional and flatness inspection, packaging in a clean, protective environment
Delivery Period:
Standard sintering plates: 30–50 days, custom-sized or reinforced plates: 60–100 days
Key Features ：
Exceptional Wear and Thermal Resistance – High hardness and low thermal expansion ensure stable performance under extreme temperatures and repeated thermal cycling, reducing deformation and maintaining structural integrity.
Corrosion and Contamination Resistance – Dense, non-porous ceramic structure resists chemical attack from acids, alkalis, and molten salts, while preventing material leaching or contamination of sintered components.
High Dimensional Stability and Precision – Minimal shrinkage and high rigidity allow precise alignment of cathodes, electrolytes, or other high-temperature parts, ensuring consistent performance in demanding applications.
