Natural diamond creates possibilities |
| |
| Natural diamond doesn't just offer solutions to difficult problems – it creates possibilities. Single crystal diamond is the material of choice for several applications, offering outstanding properties for challenging applications. Delaware Diamond Knives Inc. harnesses the extraordinary properties of natural diamond to produce unique tools and components to fit our client's requirements. |

| Properties of natural single crystal diamond: |
- Highest thermal conductivity of any known material.
- High electrical resistance
- Low dielectric constant
- Low loss tangent at microwave frequencies.
|
- Extreme hardness
- Transparency over many wavelengths
- chemically inert

| Applications |
| Our customers have asked us to fabricate diamond parts in a variety of orientations, thicknesses and dimensions for the following applications: |
- Plates for X-ray research, 500µm thick
- Thin parts for changing polarization of beam, 100µm thick
- Vacuum windows with high transmission in synchrontron beamlines
- Windows for magnetic microscope failure analysis, 25µm thick
- Anvils to withstand extreme pressure, 1mm thick
- Substrates for sensors, 50µm thick

| Characteristics |
| Natural diamonds are classified by the type and level of impurities found within them. |
- Type Ia diamond - Most natural diamonds are of this type, which contain up to 0.3% nitrogen.
- Type Ib diamond - Very rare (~0.1%) in nature, but almost all synthetic (industrial) diamonds are of this type. They contain nitrogen at concentrations of up to 500 ppm.
- Type IIa diamond - Very rare in nature, these diamonds contain so little nitrogen that it can't be easily detected by the usual IR or UV absorption measurements.
- Type IIb diamond - Extremely rare in nature. These have such a low concentration of nitrogen (even lower than type IIa) that the crystal is a p-type semiconductor (due to uncompensated B acceptor impurities).
