  • Pressure Used to Create Artificial Diamonds The Physics

    7 行However, on December 8, 1954, a scientist from General Electric subjected black carbon powder to pressures of 50,000 atmosphere for 16 hours and made two small synthetic diamonds The pressure used to create artificial diamonds varies with temperature Therefore, there is no single number for the pressure required to produce an artificial diamondIt is screened for the first time tonight (Thursday 10 May) at The Edge, University of Bath It highlights how diamond mining is Sierra Leone's most lucrativeNew film highlights human pressures of diamond industryCurrently, the deepest mine in the world is the Western Deep gold mine near Johannesburg in South Africa 1 It is over 3,500 m (or 35 km) deep from the ground level 1 and efforts are being made to deepen this mine to 4,000 m, and eventually 2 to 5,000Pressure and density of air in mines
