Diamond powders are used in a great variety of applications. Here are some examples:

1, Bonded applications:

Glass grinding is an important consumer of diamond grinding wheels. Micron powders are used to grind mirror or crystal glass and optical products, with sizes ranging between 40µ Et 120µ . Smoothing pellets, with sizes between 6µ And 40µ , require excellent oversize particle control. This also applies to honing tools.

Hard metals and ceramics grinding applications are extremely varied and specialised. Abrasive tapes are used in the electronics industry.

2, Diamond drawing dies

Micron powders up to approx. 15µ Are used for the ultrasonic shaping of natural diamond and PCD dies. The sizing and fine polishing operations are very quality-sensitive. Van Moppes has acquired a world-wide reputation with its submicron sizes, such as 0-0.25, 0.25-0.5, 0-0.5, 0.25-0.75 and 0.5-1...

3, Electronics industries

Electronics are large users of micron diamond powders, mainly in the following applications.

Magnetic heads, which are made of composite materials and are polished using micron powders ranging between 0-0.5µ And 1-3µ .

Hard disk media surfaces are textured with submicron powders, such as, for example, 0-0.2µ To achieve an Ra surface roughness in the order of 4 Angstrom and more recently with special products in the nanometer range. The quality requirements are very high, to guarantee an accurate, controlled and consistent surface roughness...

4, Ceramics

This title includes a variety of applications, such as writing balls, gauge balls, bearings, printer needle guides, or other components such as cutting tools, tap joints, electronic circuit substrates or automotive parts. Polycrystalline powders are used, as well as monocrystalline powders in both loose or bonded form.

5, Metallurgical Industries

This heading includes a wide range of applications: Metallographic samples, injection moulds, tool and die polishing, cutting tools, tungsten carbide dies, surgical instruments, hip joints, etc. These applications are shared between the use of powders and lapping compounds.

6, Lapidary industry

Precious and semi-precious jewel stones are polished with polycrystalline or monocrystalline sizes ranging between 0 and 12µ .

7, Diamond polishing

Diamond is polished with diamond. Gem diamond polishing is the largest application, mostly using monocrystalline powders between 0 and 40µ

8 Miscellaneous applications

The optical fibre industry uses submicron sizes as fine as 0-0.1µ , to Polish optical fibre connectors. Another exotic application for fine submicron powders is the polishing of microtome knives.
