Using the new green production process independently developed, the purity of 4N-5N, the primary crystal 300-500nm, 500-800nm
High purity alumina powder products for ceramic substrate can be provided according to customer requirements with different primary crystal size, morphology, specific surface, particle size,
Crystal-shaped customized products. The product has the characteristics of regular morphology, controllable particle size and distribution, high sintering activity, which can significantly reduce the sintering temperature of ceramic substrate, and make high end substrate without casting by casting method.
