The candle flame every second there is about 1, 5 million diamond nanoparticles present - these particles are burned while burning candles. Some chemists have expressed the view that the study of this process can lead to the fact that diamond production could be much cheaper. For example, Dr. Zhou tried to use some of the new methods for extracting the nanoparticles from diamond flame.
However, until now not known, that it affects the appearance of the diamond during combustion. They quickly burned and converted into carbon dioxide. However, the understanding of this process could be the key to a cheap and efficient production of diamonds.
