Alumina-Zirconia Powder AZ
Ø Feature
Alumina-Zirconia Powder AZ is a fine-grained abrasive developed as lapping material that requires high precision.
The particle size distribution is sharp, particle size is stable, and the shape is blocky. A uniform polished surface can be obtained by soft polishing.
Ø Physical Properties and Chemical Composition
l Raw Material：mixture of fused alumina and zirconia sand
l Chemical Name：Al2O3 + ZrO2
l Structure：brown grain
Ø Application
l Precision lapping materials for semiconductor crystals (silicon, etc.), compound semiconductors, etc.
l Precision lapping materials for lenses, prisms, crystals, optical glass, etc.
l Lapping materials for metals
l Other
