The novel nitride is formed from an amorphous silicon titanium nitride (SiTiN) precursor under high-pressure\/high-temperature conditions in a large volume high-pressure device. Under the conditions of 15\u201320\u2009GPa and 1800\u20132000\u2009\u00b0C, spinel-type \u03b3-Si<jats:sub>3<\/jats:sub>N<jats:sub>4<\/jats:sub>and rock salt-type c-TiN are formed. In addition, crystals of the discovered nano-sized ternary phase (Si<jats:sub>1\u2212x<\/jats:sub>,Ti<jats:sub>x<\/jats:sub>)<jats:sub>3<\/jats:sub>N<jats:sub>4<\/jats:sub>embedded in \u03b3-Si<jats:sub>3<\/jats:sub>N<jats:sub>4<\/jats:sub>are identified. The ternary compound is formed due to kinetically-controlled synthesis conditions and is analyzed to exhibit the spinel-type structure with ca. 8 atom% of Ti. The Ti atoms occur in both Ti<jats:sup>3+<\/jats:sup>and Ti<jats:sup>4+<\/jats:sup>oxidation states and are located on the Si sites.
