| Abstract: | Based on experimental data, reactivity and temperature at various points of time in the TNT detonation reaction zone and Taylor zone are calculated.The nucleation and the growth of diamond from free carbon as is formed in the TNT detonation reactive zone have been estimated by classical homogeneous crystal nucleation and growth theory. The estimated yield of ultrafine diamond is in agreement with that from the experimental data. |

| Keywords: | ultrafine diamond detonation phase transitions nucleation crystal growth |
