A method for increasing the size of the nanocrystals detonation nanodiamond

摘要

A method for increasing the size of nanocrystals detonation nanodiamond, comprising annealing by heating to a high temperature a mixture consisting of powder detonation nanodiamond and intermetallic compounds, characterized in that a powder mixture of 50% (wt.) Mixture containing 90% (wt.) detonation nanodiamond powder and 10% (wt.) of aluminum powder, and 50% (wt.) mixture of intermetallic nickel and aluminum, the appropriate stoichiometric NiAl or NiAl, then the mixture was mixed thoroughly and compressed to form cylinders, samples annealed in vacuo at a pressure no worse than 10 mm at a temperature of 950 ° C for 30 minutes.
