Introduction
In the course of hydrometallurgy, direction and kinetics of electrode course, structure patterns of
electrode, electrolytic bath and lifetime of electrolytic bath, etc. depend on the performance of the
electrode to a great extent, so the choice of the electrode is particularly important.

In view of the microstructure it is evident that the shape of C2SH (A) belongs to the fiber, but the shape of tobermorite is attributed to the plate despite the strength of tobermorite is higher than that of C2SH (A); if both were in a proper proportion to each other, they would form an interspersed structure with each other and possess higher strength.

Super-hard cutters, such as natural diamond, polycrystalline diamond (PCD), CBN and poly cubic boron nitride (PCBN), provides the most fundamental condition with high hardness material machining because of its high hardness, wear resistance and thermo-chemistry stability, and made the obvious production benefits [1].
Although polycrystalline diamond (PCD) is joined in diamond sintering mixture, its hardness and abrasive resistance are still lower than the mono-crystalline diamond Owing to its structure mixed orientation fine grain.

The increment of tensile strength up to 1phr is attributed to higher crosslink density because of the addition of small amount of calcium stearate.The addition of small amount of calcium stearate could neutralize the residual acidity to avoid ring-opening of expoxide groups, but excess calcium stearate acted as a base may influence crosslinking network structure and then lead to the decrease of tensile strength.
