Alumina Ceramics: Forging a Reliable Industrial Shield with Extreme Hardness and Ultra-High Temperature Stability
In the ongoing wave of modern industry advancing towards high precision, high reliability, and extreme environment applications, material selection often defines technological boundaries. Alumina (Al₂O₃) ceramics, with their near-extreme physical and chemical properties, have become a key solution for challenges involving high temperature, wear, and corrosion, rightfully earning the title of the "Ceramic Shield of Industry."
Performance Foundation: Data-Defined Excellence
The premier status of alumina ceramics is fundamentally established by its core performance parameters, as clearly detailed in the table below.
Property Value Unit

Microhardness 1600 HV0.5
Flexural Strength 310 MPa
Compressive Strength 2400 MPa
Fracture Toughness 3-4 MPa*m¹/²
Elastic Modulus 340 GPa
Coefficient of Thermal Expansion 7-8 10⁻⁶/K
Thermal Shock Resistance (Water Quenching) 200 ΔT°C
20 °C Volume Resistivity >10¹⁴ Ω*cm
Maximum Service Temperature 1600 °C
Core Advantages
  • Extreme Hardness & Wear Resistance: A microhardness of 1600 HV0.5 grants wear resistance far superior to most metals and alloys, effectively resisting particle erosion and long-term friction.
  • Ultra-High Temperature Fortress: With a maximum service temperature of 1600°C, it remains stable in high-temperature industrial environments such as metallurgy, glass, and ceramic sintering, resisting softening or deformation.
  • Excellent Dimensional Stability: A low coefficient of thermal expansion (7-8×10⁻⁶/K) means minimal dimensional change under drastic temperature fluctuations, which is critical for precision components and high-temperature assemblies.
  • Superb Insulation: Exceptionally high volume resistivity (>10¹⁴ Ω*cm) makes it an ideal electrical insulating material for high-temperature and high-frequency applications.
Application Overview: Confronting Extreme Working Conditions
Based on these properties, alumina ceramics have become indispensable in several demanding industrial sectors:
  • Photovoltaics & New Energy: Used for boats, rails, and rollers inside high-temperature diffusion furnaces for solar cell manufacturing. Its high-temperature resistance, purity, and low contamination ensure cell conversion efficiency and yield.
  • Oil & Gas / Mining: Employed as wear-resistant liners, nozzles, valve cores, and mechanical seal rings in drilling, conveying, and slurry handling systems. Its superior wear and corrosion resistance significantly extends equipment service life in harsh conditions.
  • Electronics & Semiconductors: Serves as a high-performance substrate, insulating ring, and heat sink in power devices, integrated circuits, and sensors, providing reliable insulation, heat dissipation, and mechanical support.
  • High-Temperature Furnace Components: The ideal material for high-quality muffle furnace liners, refractory supports, thermocouple protection tubes, and sight glasses, ensuring the safety and stability of high-temperature industrial processes.
