Cubic silicon nitride (c-Si3N4) was prepared at 37-38 GPa and ∼1773K by shock compression of residues of polysilazane, perhydropolysilazane (PHPS), pyrolyzed at 873, 1073 and 1273K for 2 h. The residues pyrolyzed at 873 and 1073K were amorphous materials, while the residue pyrolyzed at 1273K consisted mainly of crystalline α-Si3N4. The relative amount of c-Si3N4 was the smallest in the shock-compressed product of the residue pyrolyzed at 1273 K, indicating that use of amorphous residues is advantageous for formation of c-Si3N4.
