Polishing, a key process in material surface treatment, directly impacts the finish, flatness, and functionality of a workpiece. Alumina, due to its moderate hardness, controllable particle size distribution, and high chemical inertness, is a key polishing material.
Polishing Powder Performance Control
Particle Morphology Optimization
Polishing powder particle morphology (e.g., spherical, polygonal, etc.) influences polishing efficiency and surface quality. Spherical particles reduce scratching, while polygonal particles help improve material removal rate. By adjusting the preparation process, precise control of particle morphology can be achieved.
Surface Modification
The surface chemical properties of polishing powder can be modified through methods such as pickling, coating, or treatment with coupling agents. Appropriate surface treatment enhances the dispersion of polishing powder in the polishing solution and reduces agglomeration during the polishing process.
Balancing Hardness and Toughness
The hardness of alumina polishing powder must match the material being polished to avoid excessive wear or insufficient polishing efficiency. By doping or compounding with other materials, the mechanical properties of polishing powder can be manipulated to adapt it to workpieces of varying hardness.
Applications of Alumina Polishing Powder
Optical Glass Polishing
Alumina polishing powder is widely used in the precision polishing of glass components such as optical lenses and display screens, effectively removing surface defects and improving light transmittance.
Semiconductor Material Processing
In the polishing of semiconductor materials such as silicon wafers and sapphire, high-purity alumina polishing powder can achieve nanometer-level surface roughness, meeting the requirements of integrated circuit manufacturing.
Metal and Ceramic Polishing
Alumina polishing powder is suitable for the surface finishing of metal materials such as stainless steel and aluminum alloys, as well as structural ceramics, significantly improving the surface finish and aesthetics of the workpiece.
