write an informative note on structure, properties and use of diamond
Answers
Answer:
It is also chemically resistant and has the highest thermal conductivity of any natural material. These properties make it suitable for use as a cutting tool and for other uses where durability is required.
Physical Properties of Diamond
Chemical Classification Native element - Carbon
Specific Gravity 3.4 to 3.6
Most diamonds are brown or yellow in color. The jewelry industry has favored colorless diamonds or those that have a color so subtle that it is difficult to notice. Diamonds in vivid hues of red, orange, green, blue, pink, purple, violet, and yellow are extremely rare and sell for high prices. A few white, gray and black diamonds are also cut and used as gems. Most industrial-grade diamonds are brown, yellow, gray, green and black crystals that lack the color and clarity to be a nice gem.
Streak Diamond is harder than a streak plate. Its streak is known as "none" or "colorless"
Luster Adamantine - the highest level of luster for a nonmetallic mineral.
Diaphaneity Transparent, translucent, opaque.
Cleavage Perfect octahedral cleavage in four directions.
Mohs Hardness 10. Diamond is the hardest-known mineral. However, the hardness of diamond is directional. It is hardest parallel to its octahedral planes and softest parallel to its cubic planes.
Diagnostic Properties Hardness, heat conductivity, crystal form, index of refraction, specific gravity and dispersion.
Chemical Composition C (elemental carbon)
Crystal System Isometric
Uses Gemstones, industrial abrasives, diamond windows, speaker domes, heat sinks, low-friction microbearings, wear-resistant parts, dies for wire manufacturing.
