A group of scientists from two universities in China created a high quality super hard diamond in the laboratory, durable many times more natural diamonds. The team said their breakthrough creativity had many applications in key areas because diamonds are widely used in industries such as cutting and polishing tools. While most natural and artificial diamonds have a cube structure, super hard diamonds called Lonsdaleite have a hexagonal crystal structure, Interesting Engineering On February 16, reported.
Previously, the most hard diamond was only found in the mouth of the collision hole, making them both rare and small. However, researchers from Cat Lam University, headed by Liu Bingbing and Yao Mingguang, along with Zhu Shengcai at Trung Son University in Shenzhen, realized that Graphite formed a structure called “Hau period Graphite “.
The first super hard diamond model (Lonsdaleite) was discovered in Diablo gorgeket in Arizona, USA, in 1967. Although scientists realized the reproduction of similar artificial specimens was very challenging, the medium research team The country develops the almost pure hexagonal diamond diamond diamond method from Graphite. According to the research results, this artificial diamond has high quality and possesses superior characteristics. It is 40% harder than natural diamonds and more stable than nano diamonds less than 100 nanometers (a millimeter equal to one million nanometers).
The researchers explained the excellent thermal stability and the ultra -high hardness of the hexagonal diamond showed its great potential in industrial applications. Discovery also provides useful understanding of the process of converting graphite into diamond under high pressure and temperature, opening up opportunities for this unique production and use of materials.
This is not the first time the hexagonal diamond has been developed in the laboratory. In 2021, a group of US researchers reported that hexagonal diamonds were large enough to measure their hardness with sound waves. According to Travis Volz, co -author of the 2021 study and a doctoral researcher at the National Lawrence Livingmore and colleagues, hexagonal diamonds are harder than the cube diamonds, so this is the option to alternate the favorable alternative. Vietnamese for mechanical application, drilling, even used as a wedding ring in the future.
