A team of researchers from the University of Utah have discovered a new mechanism that explains the formation of non-uniform diamond tools. This mechanism is based on the observation that the tool becomes less uniform when the diamond-forming process is exposed to high temperatures.

The researchers found that when diamond-forming processes such as chemical vapor deposition (CVD) are exposed to high temperatures, the diamond crystals become non-uniformly distributed due to the formation of bubbles. These bubbles contain gas, which then expands and causes the diamond crystals to become less uniform.

The researchers believe that this new understanding of the formation of non-uniform diamond tools can help improve their performance and efficiency. They are now looking into ways to minimize the formation of bubbles and thus reduce the non-uniformity of diamond tools.
