99% alumina ceramic uses a high-purity matrix (Al2O3≥99%) and precision sintering to achieve near-corundum hardness and long-term stability above 1700℃. It offers very low dielectric loss and resistance to strong acids, alkalis and molten metals. Its dense, uniform microstructure can be polished to a submicron finish for semiconductor wafer fixtures and laser resonators, with stable performance in vacuum or inert gas. Biological inertness also extends its potential to advanced medical equipment such as artificial-joint coatings, making it a core material for precision industry and advanced technology.
常见问题
Why choose precision ceramics over conventional materials?
Precision ceramics offer excellent resistance to heat, corrosion and wear, together with electrical insulation, making them suitable for extreme conditions such as high temperatures and pressures. They also support high-precision machining for complex designs.
Which industries use precision ceramics?
Precision ceramics are widely used in aerospace, automotive, electronics, medical and industrial equipment, particularly where high performance and durability are required.
Are precision ceramics difficult to machine?
High hardness and brittleness make precision ceramics difficult to machine. Specialized equipment and processes, such as CNC machining, are needed to ensure precision and surface quality.
How do I choose the right ceramic material?
Consider the specific operating environment and performance requirements, including heat resistance, corrosion resistance and mechanical strength. Different applications require ceramics with different properties.
How long do precision ceramics last?
Precision ceramics generally offer a long service life, from several years to longer, depending on operating conditions such as temperature, pressure and wear.
