Chemshun 99.7% Aluminum Oxide (Al₂O₃) ceramic wafer polishing plate

Chemshun 99.7% Aluminum Oxide (Al₂O₃) ceramic wafer polishing plate is a high-performance ceramic material mainly used for high-precision polishing in semiconductors, optics and electronic devices. Alumina ceramics are widely used in these high-end fields due to their high hardness, high wear resistance, good chemical and thermal stability.

Below are some of the main features and applications about 99.7% alumina ceramic wafer polishing plates:

High purity: the purity of alumina reaches 99.7%, which ensures the high quality and stability of the material.

High hardness: Alumina ceramics have a very high hardness, second only to diamond, making them ideal for high-precision polishing and grinding.

Wear resistance: Due to the high hardness and good chemical stability, alumina ceramic polishing plates can still maintain good polishing performance in long-term use.

Good thermal stability: Alumina ceramics can withstand large temperature changes without being easily damaged, which gives them an advantage in heat treatment processes.

Chemical stability: alumina ceramics have good resistance to most chemicals such as acids and alkalis, and can maintain stable performance in harsh environments.

Wide range of applications:

Semiconductor industry: used for polishing silicon wafers, sapphire substrates, etc.

Optical industry: used for polishing optical glass, optical components and so on.

Electronic devices: used for packaging and support structure of precision electronic devices.

Others: It can also be used in aerospace, biomedical and other fields.

High processing precision: alumina ceramic polishing plate can achieve micron or even nanometer polishing precision to meet the demand for high-precision processing.

It should be noted that although alumina ceramic polished plate has many advantages, but its processing cost is also relatively high, because the high purity of alumina raw materials and fine processing require high cost investment. In addition, alumina ceramics are brittle, and care needs to be taken to avoid excessive stress and impact during processing and use. more information in website : www.chemshun.com
