- Image Analysis
Surface Area Analysis (surface area determination):
Bulk Purity Analysis (nature & concentration of extrinsic contaminants in diamond & CBN powder):
- X-Ray Diffraction – qualitative phase analysis
- Inductively Coupled Plasma (ICP) Spectroscopy – quantitative elemental analysis
Chemical Composition Analysis (nature & concentration of intrinsic impurities in diamond & CBN particles):
- Inductively Coupled Plasma (ICP) Spectroscopy – quantitative elemental analysis
Surface Cleanliness Analysis (ionic content):
- Ion Chromatography (IC) Analysis – nature & level of anions and cations associated with the diamond surface
- Electrical Conductivity Determination (ionic content)
Crushing Strength Determination:
