Diamond is very hard in nature due to because of its complex network of carbon atoms. The three dimensional structure of diamond tends its density very high and its structure become more rigid and compact. … Due to this reason diamond is used for making cutting tools (like glass cutters) but not graphite.
Why is diamond used for making cutting tools but it is not?
Diamond is the hardest, naturally occuring material known. Owing to its rigid structure, it can be used as glass cutters. Whereas graphite is a layered structure of carbon atoms and is very soft so, it cannot be used for making cutting tools.
Is diamond used to cut iron?
Diamond is great cutting tool material, but diamond tools (actually technically PCD tools) cannot cut ferrous metals like Steel or Cast Iron. Here’s the reason. Diamond is essentially pure carbon, with atoms arranged in a cubic crystal arrangement that makes it very strong.
Why is diamond a poor conductor of electricity?
As we know diamond is a giant covalent structure i.e. each carbon atom is covalently bonded with other carbon atoms. So the four outermost electrons, four carbon atoms, are engaged or trapped in the covalent bonds which means that there are no free electrons. … So diamond is a bad conductor of electricity.
Why carbon is used in cutting tools?
Carbon tool steel
High carbon steels are abrasion resistant and have the ability to maintain sharp cutting edge. Carbon tool steels possess good machinability. This material loses their hardness rapidly at a temperature about 250°C. Therefore, it can’t use high-temperature application.
Why diamond is not used for cutting steel?
The primary reason why diamond tools are not suitable for cutting metals such as Fe, Cr, Ti, Ni, etc, is that the chemical reaction between the diamond and the workpiece material, which results in severe wear and tear of the tool, including oxidation reaction, graphitization and chipping [13, 34, 36–39], as shown in …
Does diamond cut metal?
Will Diamond Blades Cut Metal? Yes, certain diamond blades can cut through metal, but this will depend entirely on the blades application. Most diamond blades are used to cut through concrete, brick, tile, and asphalt. … Instead, the best tool for asphalt cutting is a diamond blade with a hard bond.”
Why is it called a diamond blade?
Simply put it means that as more diamond is added to the segment more horsepower is needed to make the blade cut. In practical terms this means that blades for high horsepower saws will have more diamond in the segment.
What is diamond used for?
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.
Can a diamond conduct heat?
Unlike most electrical insulators, diamond is a good conductor of heat because of the strong covalent bonding and low phonon scattering. Thermal conductivity of natural diamond was measured to be about 2200 W/(m·K), which is five times more than silver, the most thermally conductive metal.
Is diamond soft or hard?
The rigid structure, held together by strong covalent bonds, makes diamond very hard.
