We drilled, cut and proposed with diamond for centuries — it took a laser to learn we were off by 700°C.
Diamond's melting point was off by 1,300 degrees, laser experiment reveals
Researchers at a national laser facility used powerful shock waves to melt diamond and measure its melting point directly, finding it about 700 degrees Celsius (1,300 Fahrenheit) higher than prior experiments had suggested. The revised figure matters for fusion research, where diamond capsules are compressed by lasers to trigger the reactions that power stars. The team's data will feed models predicting how diamond behaves under extreme shock.
