Diamonds are harder than iron, why can hammer easily break the diamond? Diamonds, also known as diamond, are a very valuable metal. Many people are proposing to propose. When they get married, they like to buy diamonds. The larger the diamond, the higher the price. Diamonds are the most hard -hard natural metals in the world. Although diamonds are harder than iron, why can hammer easily break the diamond? Next, I will tell you the answer. The diamond is due to the minerals composed of carbon substances. It is a alifamic alien body of graphite. Each carbon element of a large diamond is surrounded by four electrons. The price key constitutes a positive tetraonal body. The reason why the diamond is so hard is this. The diamonds are not only strong, but also high, and the melting point is high. In addition to a valuable metal, diamonds are also generally used in the probe grinding tool for diamonds in the industry. High diamond strength does not mean that diamonds are not easy to break. The ductility of the material, if the ductility is good, can make a variety of shapes, metal gold, because the golden ductility is very good, so gold can be made into gold silk. The reason why the hammer can easily crush the diamond is that the hammer is a metal product with a good ductility. The diamond has a poor ductility, so the diamond is easily crushed by the hammer. The number of natural diamonds is very small and expensive. With the development of science and technology, more and more scientists have begun to study diamonds. In 1955, the United States General Electric Corporation created the first batch of industrial artificial diamonds. Since then, the road of industrial large -scale production of human -made diamonds has been started. There are many ways to manufacture artificial diamonds, but it is mainly attributed to the following three direct methods and melting melting. Media and extension, artificial diamonds are lower than natural diamonds and have a larger number. Therefore, artificial diamonds are used in large quantities to industrial production. For example, cutting glass cutting knives uses artificial diamonds.
First of all, we need to understand that the so -called hardness refers to the ability of the material surface to resist squeezing, that is, abrasion resistance. The carbon atom structure inside the diamond is arranged into tetrahedron, which is very stable, so the diamonds are high. But this also causes some cracks and misplaces of diamonds. This principle is also used for diamond cutting. If there are diamonds with obvious cracks and inserting special tools in the cracks, you can get two diamonds with low internal purity but high value.
It slightly polishing can eliminate external defects. For example, the glass hardness of the mobile phone screen is relatively low, and scratches will appear after a long period of use, so there are too many stalls in the mobile phone film. Similarly, because the diamond is hard enough, the tool used to cut the glass is to use diamonds to achieve a hard -hard purpose to cut the glass. Secondly, because the brittleness or fracture toughness of the diamond is different from the hardness, it can be smashed with a hammer. Its fracture toughness is several levels lower than the metals such as hammer. If the metal tool is used to scrape the surface of the diamond, it will basically not scratch, which is a manifestation of its hardness; but it is different with the hammer. At this time, the principle of use is that the metal's fracture toughness is higher than that of diamond, so it can be crushed. In short, due to its low crispyness, diamonds are similar to glass in impact. This is why the mobile phone screen is easily broken once it falls. Someone has developed a gem screen that has developed a mobile phone, but it cannot be officially released, because even if the diamond screen is used, the screen of the mobile phone will still break, but it can increase wear resistance and has little meaning to users. We should also pay attention to the diamond ring and other accessories, do not fall or smash them, otherwise they may break or even break. The famous crispy case is that the Titanic sinks. We all know that the ship broke down quickly after hitting the iceberg. Theoretically, the ship represented the highest shipbuilding technology at that time and used the strongest materials. Not so fragile. When investigating the real cause of the accident, the experts found that the hits part of the steel plate containing a large amount of sulfide, which was to unilaterally increase the hardness of the hull, but ignored its brittleness. When the ship is close to the glacier, the crispness of the steel will increase sharply due to the low temperature of the seawater, and the unprecedented tragedy will occur. Therefore, the people on the ship have no time to respond.

Although the diamond is relatively hard, it can't hold the power of the hammer. The pressure on it is very strong, so it is easier to break.
Because diamonds are also fragile and cracks will occur, they can be easily crushed.
