Preparation method of alumina with ultra-high purity |
| abstract |
The present invention relates to a method for producing an ultra-high purity alumina (Al 2 O 3 ) having a purity of 99.99% or more by lowering the content of impurities including transition metals to below 100 ppm by using ammonia water and ammonium alum, (Alumina) has superior sintering characteristics compared with alumina manufactured by other methods. It is a raw material for manufacturing sapphire single crystals (smartphone glass, smartphone camera cover, LED substrate (wafer) ) As well as sodium tubes, catalysts and the like. |
