Diamond Materials
Diamond combined with other materials, from composites to nanoparticles.
Start here · Essential guide
A plain-language tour of the diamond materials family used in industry: grit, sintered compacts, coatings, films, composites and nanodiamond, and what each does.
How sintered diamond compacts are held together by a binder phase such as cobalt or silicon carbide, and how that binder limits heat tolerance and performance.
What a composite is, how diamond particles are combined with metals or ceramics, and why the bond between diamond and matrix decides how well the result performs.
A technical look at the measured properties of diamond materials: hardness, thermal conductivity, expansion, toughness and stability, and why values vary by form.
How the choice of matrix, whether metal, ceramic or polymer, shapes the heat, wear and manufacturing behavior of diamond composites, and what each option costs.
A review of how diamond composites spread heat in electronics and high-power equipment, covering the role of thermal conductivity, expansion matching and interfaces.
An introduction to nanodiamond particles: how they are made, what sets them apart from larger diamond grit, and where they are used as additives.
A cautious summary of nanodiamond research: sensing, biomedical studies, polymer reinforcement and lubricants, and which results remain early stage.
