Remarks:Senna makes alumina ceramic products of special structure and shape according to the given drawing.
Alumina Tube：
1、Big caliber ceramic tube made of 92% alumina is widely used in industry of minning,power,metallurgical,coal,chemical. In some special site where wear plates can not service well,ceramic tube is a perfect substitute,it is a solution to problem of partial wear plate off and has been enjoy high reputation.
2、Big caliber ceramic tube made of 95% alumina is used as lining of hydraulic cyclone for paper-making and mineral separation.And most of the textile ceramic component s are made of alumina 95%.
3、Most of the ceramic spools,structural ceramic components and ceramics for military application are made of alumina 99%.The future is bright and the consumption quantity is increasing year by year.
