WebMar 27, 2014 · One way to turn graphite into diamond is by applying pressure. However, since graphite is the most stable form of carbon under normal conditions, it takes approximately 150,000 times the atmospheric pressure at the Earth's surface to do so. Now, an alternative way that works on the nanoscale is within grasp. WebJul 24, 2024 · How Much Pressure Does It Take To Turn Coal Into Diamond? July 24, 2024 by Kristen Mckenzie. It will take 725,000 pounds of carbon per square inch to squeeze it. One carbon atom to four other carbon atoms are bonded to by the temperature and pressure of the carbon atoms. That is the reason a diamond is so hard. bison and antelope roam this flat ecosystem
