During the sintering of the composition diamond powder of dynamic synthesis and the diamond powder of the catalystic synthesis only at sintering temperature 2200 С boundaries formate between monocrystal grains from diamond powder of dynamic synthesis and the diamond powder of catalystic synthesis. The technique of measurement of the compression strength of the diamond materials was developed using non-diamond indentor spherical form.
