99% Alumina
99% Alumina: 99% alumina ceramics are based on ultra-high purity alumina matrix (Al₂O₃≥99%), achieving ultimate hardness (approaching corundum) and ultra-high temperature stability (long-term resistance to temperatures above 1700.
C) through precision sintering processes. They also exhibit extremely low dielectric loss and ultra-high chemical corrosion resistance (resistant to strong acids, strong alkalis, and molten metal erosion). Their microstructure is dense and uniform, and the surface can be ultra-finely polished to submicron-level smoothness, making them suitable for high-precision applications such as semiconductor wafer fixtures and laser resonators, and capable of maintaining stable performance in vacuum or inert gas environments. Furthermore, their bio-inert properties expand the application potential of high-end medical devices (such as artificial joint coatings), making them one of the core materials in precision industries and cutting-edge technology fields.
FAQ
Precision ceramics offer superior high-temperature resistance, corrosion resistance, wear resistance, and insulation, making them ideal for extreme conditions like high temperatures and high pressure. They also support higher precision processing, meeting complex design needs.
Precision ceramics are widely used in aerospace, automotive, electronics, medical, and industrial equipment industries, especially in applications requiring high performance and durability.
Precision ceramics are challenging to machine due to their high hardness and brittleness. Special equipment and processes, such as CNC machining, are required to ensure precision and surface quality.
When selecting a ceramic material, it is essential to consider specific working environments and performance requirements, such as high-temperature resistance, corrosion resistance, and mechanical strength. Different applications require ceramics with varying properties.
Precision ceramics generally have a long lifespan, with their longevity ranging from several years to even longer, depending on the usage environment (such as temperature, pressure, wear, etc.).
