Diamond powder of an suitable grain dimension (all over 50 microns) burns with a shower of sparks following ignition from a flame. For that reason, pyrotechnic compositions depending on artificial diamond powder may be geared up.
Another preferred approach to escalating synthetic diamond is chemical vapor deposition (CVD). The expansion happens beneath low pressure (below atmospheric force). It will involve feeding a mixture of gases (usually one to 99 methane to hydrogen) into a chamber and splitting them into chemically Lively radicals in the plasma ignited by microwaves, very hot filament, arc discharge, welding torch, or laser.
Most diamonds come from the Earth's mantle, and many of the segment discusses Those people diamonds. However, there are actually other sources.
