Cabezal de indentación de alúmina 99

In the field of micro and nanomechanical testing, the harsh testing environment (such as high temperature and strong corrosion) often leaves traditional diamond or sapphire indenters helpless. We have launched a high-performance Cabezal de indentación de alúmina 99 to address the pain points in this industry. This product is not only a tool for material science research, but also a reliable guarantee for industrial quality control to cope with special environments.

Product core advantage: Why is 99 alumina the ideal choice?
99 alumina (Al ₂ O3) exhibits irreplaceable advantages in specific application scenarios due to its excellent physical and chemical properties:

1. Excellent chemical inertness and high temperature stability:
   Advantage: It can remain stable in oxidizing or inert atmospheres up to 1700 ° C and does not react with most metal and semiconductor melts. This is incomparable to diamond (which graphitizes above 450 ° C) and sapphire (a single crystal form of Al ₂ O ∝, but expensive).
   Problem solving: Perfectly solved the difficulties of high-temperature in-situ nanoindentation testing and testing in corrosive environments.
2. Dureza y resistencia al desgaste extremadamente altas:
   Advantages: The Mohs hardness is as high as 9, second only to diamond, ensuring that the indenter can maintain a sharp geometric shape during long-term and repeated testing, thereby ensuring the long-term accuracy and repeatability of test data.
   Problem solving: Reduced experimental errors and data drift caused by wear on the tip of the indenter, and lowered the cost of frequent replacement of the indenter.
3. Excellent insulation:
   Advantage: It is an excellent electrical insulator, suitable for complex mechanical testing scenarios that require synchronous electrical performance testing (such as conductivity and piezoelectricity).
   Solution: Avoiding the interference of conductive indenter on electrical signal measurement, providing the possibility for multifunctional coupling testing (such as the combination of piezoelectric force microscope PFM and nanoindentation).
4. Cost effectiveness of optimization:
   Advantages: Compared to single crystal sapphire indenters of the same size and accuracy, 99 alumina polycrystalline ceramic indenters achieve better cost control through advanced powder metallurgy and precision machining technology.
   Problem solving: Provides a cost-effective option for research teams and industrial laboratories with limited budgets but requiring high-performance ceramic indenters.

Main application scenarios
High temperature nanomechanical testing: used to study the creep, phase transformation, softening behavior, etc. of materials (such as high-temperature alloys, refractory metals, ceramics) in high-temperature environments.
Testing in Corrosive Environments: Applied in the fields of chemical engineering and energy, testing the mechanical property evolution of materials in acidic, alkaline, or molten salt environments.
Semiconductor and thin film materials: Accurate hardness and modulus measurement of insulating films and passivation layers without conductive interference.
Multi functional coupling testing platform: used in conjunction with electrochemical workstations, high-temperature tables, etc., to conduct in-situ mechanical testing under multi field coupling.
