Alumina ceramic blocks and irregularly shaped ceramic structural components are widely used in industrial fields due to their unique physical and chemical properties.
Core Characteristics
1. Ultra-high hardness and wear resistance: Mohs hardness reaches 9 (second only to diamond), and wear resistance is 20 times that of stainless steel, which can significantly extend the service life of equipment such as mining crushers and conveyor pipes.
2. Excellent high-temperature resistance and insulation: Withstands temperatures up to 1400℃ (steel softens at 800℃), and has a dielectric strength of >10 KV/mm, suitable for high-temperature furnaces, aerospace thermal insulation components, and electronic insulation applications.
3. Chemical corrosion resistance: After immersion in a 30% sulfuric acid solution for one year, the mass loss is <0.01 grams, far superior to 316L stainless steel, making it suitable for chemical reactor linings.
4. Adaptability to complex structures: Supports customized designs such as porous bases, miniature gears, and threaded connectors, meeting the needs of precision fluid control (such as semiconductor nozzles).
