High-purity, ultra-fine ceramics powder produced from aluminum chemical synthesis method.
Developed based on the synthesis of ammonium dawsonite (NH4AlCO3(OH)2).
Application
- High-strength, wear-resistant material: artificial bones/dental materials, bearings, etc.
- Electronic materials: IC boards/semiconductor manufacturing jigs, sensors, etc.
- Optical material: translucent ceramics, ruby, YAG, etc.
- Others: Various fillers, synthetic spinel, catalyst carriers, etc.
Low temperature sinterable alumina
Taimicron for sintering is a high-purity α-alumina powder that can be sintered and densified at extremely low temperatures because the primary particles are fine and single particles.
Features
- Ultra-fine ceramics powder with high-purity of more than 99.99%.
- Low temperature sintered and densified alumina.
It densifies to 98% or more of the theoretical density by firing at 1250°C to 1300°C.
- Excellent sintered powder that obtain the original characteristics of alumina.
High-strength, high-hardness, high wear-resistance and corrosion resistance ceramics.
- Easy to obtain translucent ceramics.
By HIP sintering, etc., it becomes translucent ceramics.
