Reactive Alumina Powder

The reactive alumina powder made through specially sintering process, grinding process and multistage powder size separation, has high purity, good particles size distribution and excellent sintering activity, which is suitable for the application in the production of high performance refractory material, and electronic ceramics products. The reactive α-alumina micropowder can be well controled in particle size distribution in the range of submicron, leading to be with excellent grain packing density good rheological property and stable workability as well as good sintering activity, which play an unique role in refractory:

1. By optimizing the particle accumulation to reduce the addition amount of water;

2. The wear resistance and mechanical strength are improved by forming a solid ceramic bonding phase;

3. The high-temperature performance of the product is improved by replacing the ultra-fine powder with low refractoriness.

25kg/bag,1000kg/bag or other specific packing according to user’s requirements.
