Alumina(Al203)
Alumina consists of oxidized aluminium and is the most popular among all fine ceramics.
High-purity alumina ceramic series is the ceramic material with Al2O3 content 99.5% and 99.9%.
A. Electrical Insulating properties
B. Wear Resistance
C. Heat Resistance
D. Corrosion Resistance
E. Plasma Resistance
Main Applications
A. Semiconductor manufacturing equipment parts(chamber parts,insulation flanges,etching equipment parts,wafer chucks)
B. Crusher parts(classifiers,airflow type crushers,beads mills)
C. General Industrial parts(nozzles for laser processing machines,shafts,bearings)
D. High precision,heat resistant tool(positioning jigs,assembly jigs)
E. Wear resistance parts(wire drawing machine guide rollers,yarn paths,rails,guides)
F. Electrical insulation parts(insulators,spacers,bushes)
Features
Alumina is usually a white or cream colored ceramics.
our lineup includes alumina with hight-purities of 99.5% and 99.9%.Due to its electrical insulating properties,from early on it has been used in various electrical components.Alumina is large amounts are used and it is the least
expensive of all fine ceramics.It is also possible to manufacture large products,high purity type has high mechanical
strength and excellent corrosion resistance.In addition,it is used for parts of CVD equipment and etching equipment
because it is also excellent in plasma resistance.
