Blue monocrystalline aluminum oxide
Blue monocrystalline aluminum oxide is made in high purity α-al2O3,and fused at high temperature in the furnace.It has the characters of high toughness and hardness.As the crystalline grow very well and stackup one by one very well,the cutting and the grinding in the working is very sharp and long life.Comparing with other abrasives,the performance of blue monocrystalline aluminum oxide is higher and the surface is greater.
