High purity alumina ceramic balls are high-performance ceramic materials mainly made from high-purity alumina (Al2O3) powder through precision manufacturing processes. Its main characteristics include high hardness, high wear resistance, corrosion resistance, high temperature stability, and chemical stability.
主な特徴
高純度： With an alumina content of over 99%, it ensures excellent physical and chemical properties and will not contaminate the grinding materials.
硬度が高い： The Mohs hardness reaches 9, second only to diamond, and can maintain extremely high wear resistance under high pressure and temperature.
耐摩耗性が良い： Smooth surface, low friction coefficient, effectively reducing wear and extending service life.
強い耐食性： Aluminum oxide is an inert material that does not react with chemicals such as acids and bases, and can be used stably in complex chemical environments.
高温安定性： able to maintain stability in high temperature environments, withstand temperatures up to 1500 ℃ or even higher, suitable for high-temperature processes and special environments.
高い機械的強度： It has high compressive strength, is not easy to break or shatter, and can withstand significant pressure.
電気絶縁性能： It is a high resistivity electrical insulation material suitable for situations that require insulation.
Appearance and Manufacturing:
The appearance is white spherical, with diameters ranging from 0.5mm to 90mm. Depending on the manufacturing process, it is divided into rolling balls and pressing balls.
The manufacturing methods include green pressing, injection molding, and impregnation.
応用分野：
Ceramic factory: used for processes such as ceramic molds and ceramic cutting.
Non metallic processing industry: grinding of materials such as quartz, feldspar, gypsum, melamine, calcium powder, kaolin, etc.
Metal ore processing industry: grinding of copper ore, gold ore, zinc oxide, lead-zinc ore, etc.
Metal polishing: used as a filler for wear-resistant materials.
化学産業： used in equipment such as ball mills, vibration mills, planetary mills, etc. to improve production efficiency and product quality.
触媒担体： acting as a catalyst covering, supporting agent, and protective agent in chemical process equipment.
High purity alumina ceramic balls are a high-tech ceramic material with excellent comprehensive performance, playing an important role in many industrial fields.
