Compared with the flame melt method crystal and cake material, the sapphire polycrystalline billet has the following advantages:

 1 .High purity :Sapphire polycrystalline was  in a very clean environment during its production process ant in no contact with any  metal and relative atmosphere,which makes its purity guaranteed.

 2. High proportion:The single weight of sapphire polycrystalline  is more than 50 kilograms and the proportion is higher than 3.5g/cm³.The same size of crucible can be placed by heavier sapphire crystal and helps the growth of big crystal

3.Growth crystal has few bubbles and high quality:due to the sapphire polycrystalline experienced the high temperature melt,there is low air in the billet,the growth crystal has few bubbles and has high quality.By contrast, using 60Kg growth crystal polycrystalline billet could get 300-700mm of 2 inch crystal bar,which improves the utilization rate of single crystal sapphire,lower the single crystal cost.It could meet all the needs of growth method for sapphire raw materials
