Alumina ceramic sheet
Alumina ceramic sheet is a high-performance ceramic product made from high-purity alumina (Al₂O₃) powder through high-temperature sintering.
It features high hardness, excellent wear resistance, good electrical insulation, high temperature resistance and chemical corrosion resistance. With stable performance and high cost performance, it is widely used in electronic substrates, mechanical wear parts, insulation components, chemical anti-corrosion equipment and new energy industries.
Applications
Electronics & Electrical Appliances: Ceramic substrates, LED heat sinks, thick-film circuits, high-frequency insulating components, insulation for electric heating devices
Mechanical Wear-Resistant Materials: Wear-resistant linings, gaskets, bearings, wear-resistant valve components, textile ceramic parts
Semiconductors & New Energy: Sintering plates, ceramic supports, high-temperature insulating components for lithium batteries/photovoltaics
Chemical Corrosion Protection: Acid and alkali resistant linings, corrosion-resistant nozzles, components for filtration and reaction equipment
Medical & Food: Medical device components, wear-resistant and corrosion-resistant parts for food machinery
Aerospace: High-temperature insulation components, insulating structural components
Performance
Alumina ceramic sheets possess extremely high hardness and wear resistance.
Mohs hardness 9 (second only to diamond), Rockwell hardness HRA 80–90.
Wear resistance is 200–260 times that of manganese steel and 170 times that of high-chromium cast iron.
Suitable for: High-wear applications (mining, coal, cement, metallurgy).
Excellent electrical insulation
Resistivity >10¹⁴ Ω·cm, low dielectric loss at high frequencies.
Breakdown strength 10–25 kV/mm.
Suitable for: PCB substrates, LED heat sinks, 5G filters, high-voltage insulation components.
High temperature resistance and thermal shock resistance
Melting point 2050℃, long-term operating temperature 1200–1600℃.
Low coefficient of thermal expansion (~8×10⁻⁶/℃), less prone to cracking under rapid temperature changes.
Corrosion resistance and chemical stability
Resistant to strong acids, strong alkalis, salts, and organic solvents.
Applications: Lining of chemical pipelines, pumps and valves, corrosion protection and sealing.
Other advantages: Smooth surface, low coefficient of friction, non-stick.
Non-toxic, biocompatible (medical implants, food machinery).
High cost-performance ratio (superior to SiC, ZrO₂, and silicon nitride).
