Diamond is used for
making crucible for melting metals
making carbon brushes for electric motors
as bearings in watches
In nuclear reactors as moderators
Answers
Answer:
They are known particularly for their use in jewelry, such as rings or necklaces, because of their durability and their luster. However, most diamonds are used industrially. Because of their hardness, diamonds are extremely useful when used to cut, grind, or drill other materials.
Crucible steel is steel made by melting pig iron (cast iron), iron, and sometimes steel, often along with sand, glass, ashes, and other fluxes, in a crucible. ... Huntsman used coke rather than coal or charcoal, achieving temperatures high enough to melt steel and dissolve iron.
A carbon brush is a sliding contact used to transmit electrical current from a static to a rotating part in a motor or generator, and, as regards DC machines, ensuring a spark-free commutation. Five brush grade families are used for brush manufacturing.
Jewels (rubies) are used as bearings to reduce friction at critical points, to improve the accuracy and durability of watches. One of the hardest materials after diamond, ruby (a corundum) do not wear – almost. As a consequence, jewels can be made very smooth which allow low friction with metal pivots
Slow neutrons strike nuclei of uranium-235, causing the nuclei to fission, or split, and release fast neutrons. The fast neutrons are absorbed or slowed by the nuclei of a graphite moderator, which allows just enough slow neutrons to continue the fission chain reaction at a constant rate
