Alumina ceramic cleaning stone

Alumina ceramic cleaning stones are high-performance cleaning tools made primarily from high-purity alumina (Al₂O₃), possessing the following core characteristics and application advantages:

Core Characteristics

1. Ultra-high hardness and wear resistance: With a Mohs hardness of 9 (second only to diamond), its wear resistance is more than 200 times that of stainless steel, making it suitable for long-term, high-frequency use without significant wear.

2. High temperature resistance and chemical stability: It can withstand temperatures up to 1600℃ and is resistant to strong acids and bases, making it suitable for extreme environments such as those found in the chemical and metallurgical industries.

3. Precision cleaning capability: The surface roughness can be controlled at the nanometer level (Ra<0.02μm), effectively removing particulate contaminants from equipment surfaces and preventing metal contamination.

Application Scenarios

1. Semiconductor equipment cleaning: Used for residue-free cleaning of components such as lithography machine chambers and wafer stages, ensuring process accuracy.

2. Industrial machinery maintenance: Used as a wear-resistant cleaning tool to remove dust and impurities from conveyor belts, bearings, and other components.

3. Precision instrument polishing: Such as deburring of metal parts and polishing of ceramic components, compatible with both dry and wet environments.

Supports custom specifications.
