Polycrystalline diamond and synthetic diamond distinction

Polycrystalline diamond and synthetic diamond have in common Oh
First, there HPHT synthetic diamond diamond, usually single-crystal diamond, CVD diamond single crystals can also be a polycrystalline oh
Hardness you have to consider all the various diamond crystal surface hardness, polycrystalline with isotropic, then the hardness is the same
And then the single crystal (111) plane is the most hard, the (100) direction of the softness of the single crystal (111) diamond hardest
Polycrystalline centered, single crystal (100) Min
PCD is a synthetic diamond single particle basis by a special process of production from the current sintering mechanism in accordance with polycrystalline diamond can

be roughly divided into three types, namely, sintered, growth pattern and growth - sintered. The main product is sintered type (S-type)

, Based on the polycrystalline diamond powder as raw material, with or without additives and with additives temperature and pressure conditions, so that a block of

sintered agglomerates, its structure and cappuccino that is more similar to the crystal arrangement disorderly , no direction, no cleavage plane. This is the most

significant of diamond

One of the features, so in the course of a micro blade broken, and will not occur in brittle fracture under shock loading, chipping caused by non-cutting wear and tear

damage. In this way, the service life can be significantly extended.
