Diamonds are natural gemstones formed under the conditions of high temperature and high pressure deep in the earth. Through some knowledge of diamond knowledge, we know that diamond has the characteristics of high hardness, high refractive index and high dispersion rate, and its melting point also reaches 3550°C-4000°C, so can diamond be burned with fire? Tell everyone through the diamond burning experiment below, it’s best not to try it lightly!
Can diamonds be burned with fire? The answer is "Yes." Although diamonds are relatively hard and have a relatively high melting point, they mainly reach a high enough temperature so that diamonds can burn.
How do diamonds burn
The ignition point of diamond is 720-800℃ in pure oxygen, 850-1000℃ in air, and 2000-3000℃ under vacuum. As long as the temperature is high enough, diamond can burn. But what needs to be understood is that diamonds cannot be ignited directly with an open flame. If it is of high energy, it will explode if it is in the fire for a long time.
How do diamonds burn? You can use a long focal length convex lens to focus the diamond and burn it. The specific method is to take a magnifying glass in sunny weather, aim the magnifying glass at the diamond outdoors, make the focal point of the magnifying glass to be the smallest, and wait for the change.
Changes after the diamond burns
The above is the picture of the diamond burning. Through this animation, it can be found that the volume of the diamond is reduced when the temperature is high, and then it will change from a solid to a gas, that is, a mineral composed of carbon elements becomes carbon dioxide. Therefore, it is recommended that you do not try this kind of experiment lightly, so as not to cause property losses.
In the beginning, scientists discovered that diamonds can be burned, thus revealing the mystery of the chemical composition of diamonds. In 1722, the French chemist Lavoisier conducted an experiment on burning diamond. He placed the diamond in a glass cover and used a magnifying glass to gather sunlight to burn the diamond and obtain a colorless gas. Through verification, it is found that this gas is CO2, which proves that diamond (that is, diamond) is composed of carbon.
Diamonds can be burned into carbon dioxide gas through high temperature, but you don't need to pay too much attention to these when you wear them. After all, the open flames we usually encounter cannot reach the temperature of burning diamonds. However, you still need to pay attention to wearing diamond jewelry in normal times. It is best not to be close to open flames, especially in kitchens, to avoid oily smoke adhering to the diamond surface.
