            high purity aluminum oxide powder

            WHA series high purity aluminum oxide powder
                This product is a white powder with uniform size,low water content,stable chemical property and crystal phase,hardly soluble in acid and alkali and good sintered activity.WHA-(301-308)series high purity aluminum oxide are prepared by different technolgoy respectively .They can be used in the field of fluorescence powder with tribasic color and long After low,jewel,high pressure sodium lamp,glass additive,electric ceramic and catalyst carrier etc.the customers are satisfied with the excellent physic-chemical properties of the product.It is specially used for electric ceramic,fluorescence powder with long after low and paints.
                It can meet the requirement of blue and green powder in tribasic color powder due to the fine and uniform,regular arrangement and good fluidity of the product.It is suitable for the jewel preparation due to the high purity regular spheric or elliptic particle and fluidity,and for high pressure sodium lamp preparation due to high purity and good sintered activity.
                It can be used as catalyst carrier with long service life due to the stability and activity of the product at high temperature .
                It can be used as glass and special glass additives due to trace amount impurity of Fe and transitional elements existed in the product and resulted in good property of glass goods.
                It has good ratio of performance/price due to high purity aluminum oxide with 99.5%-99.9% of the product.
