Why are diamonds valuable humans?
Physical Properties. Diamonds have a range of physical properties which give them value. They are one of the hardest materials known to man, and can cut glass, marble and granite. They are thermal conductors, resistant to pressure and act as electrical insulators.
How is diamond useful to us?
Uses of a Diamond:
Diamond is considered to be the hardest non-metal present on earth and is used to cut metals and glass. Diamond-tipped tools are used to cut or drill various objects. Diamonds are also used to heat the sinks that are used to conduct the heat apart from the sensitive parts of the microelectronics.
Why is diamond used in jewelry?
(a) Diamond is used in making jewellery because it has a sparkling surface due to high refractive index. It can be cut and polished.
What are the useful properties of diamond?
Besides the hardness, diamond provides an impressive combination of chemical, physical and mechanical properties:
- Low coefficient of friction.
- High thermal conductivity.
- High electrical resistivity.
- Low thermal expansion coefficient.
- High strength.
- Broad optical transparency from ultra violet to infra red.
What are the two uses of diamond?
Uses of diamonds are as follows:
- used in ornaments.
- used in glass cutting and rock drilling machines.
- diamond dust is used for polishing other diamonds.
- diamond is used to make windows giving protection from radiation in space and in artificial satellites.
- diamond knives are used in eye surgery.
