Product Description
Polishing alumina is a high-purity alumina powder specifically designed for precision polishing and surface treatment. It features high hardness, uniform particle size, good dispersibility, and strong chemical stability. The polishing alumina powder produced by Zibo Xiangrun Environmental Engineering Co., Ltd. is suitable for various high-precision polishing processes and exhibits uniform particle size and excellent dispersibility.
As a common alumina polishing powder and aluminum oxide polishing powder, this product is widely used in the surface finishing of sapphire, ceramics, silicon, optical glass, metal parts, and electronic materials. For processes requiring stable cutting forces, low scratch rates, and high surface consistency, polishing alumina powder is an ideal choice that balances efficiency and surface quality.

Advantages of polished alumina
Ultra-high hardness, close to diamond hardness, can efficiently polish hard materials (such as sapphire, silicon carbide, ceramics, etc.), with strong cutting force and low wear rate.
Excellent chemical stability, acid and alkali resistance, high temperature resistance, does not react with most solvents, and avoids contamination of workpieces.
High purity, extremely low impurity content, especially suitable for semiconductors, optics and other fields with high cleanliness requirements, reducing surface scratches or impurity residues.
Controllable particle size and uniform distribution, wide particle size range, can accurately match the needs of rough polishing to mirror polishing.

FAQ
Q: What is the particle size distribution? Can you provide the data?
A: Of course, the particle size is very consistent.
Q: How long does it take to deliver?
A: It will be prepared for you immediately after placing the order.
Q:What materials are suitable for polishing alumina?
A:It can be used for high-precision polishing of hard materials such as sapphire, silicon carbide, and ceramics. In practical applications, it is also commonly used for the finishing of optical materials, electronic ceramics, and some high-hardness metal surfaces.
Q:How to choose different grit sizes?
A:Generally speaking, finer grit sizes are more suitable for fine polishing and processes with high surface quality requirements, while larger grit sizes are more suitable for stages requiring higher removal rates. Specific selection should be determined based on the workpiece material and surface roughness requirements.
