Sapphire polycrystalline compared to billet the Flame Crystals cake material, has the following advantages:

1, high purity: Sapphire polycrystalline embryogenic material in the preparation process in a very clean environment, and does not contact any metal and atmosphere, and its purity is guaranteed;
2.Sapphire polycrystalline bars with good significant: sapphire polycrystalline billet single weight greater than 50 kg, is greater than the proportion of 3.5g/cm3, the same size as the crucible can be placed more weight, and is conducive to the growth of large crystals;
3, the grown crystal bubbles less high quality: polycrystalline blank after a high temperature melting, embryo compound gas content low, high crystal quality, the crystals grown in bubble. By comparison, the use of polycrystalline blank
Growth of 60 kg of crystals can be than Flame crystalline material grown crystals pay an extra two inches of the ingot 300-700mm, improve the utilization of the sapphire single crystal, the reduced monocrystalline cost.
    The company can provide the following specifications:
     Density ≥ 3.5g/cm3
     Diameter: according to user requirements
     Height: according to user requirements
     Purity ≥ 99.998%
To meet the various growth methods sapphire raw material needs.
