Journal ArticleDOI
Melem (2,5,8-triamino-tri-s-triazine), an important intermediate during condensation of melamine rings to graphitic carbon nitride: synthesis, structure determination by X-ray powder diffractometry, solid-state NMR, and theoretical studies.
TL;DR: A good agreement was found between the observed and calculated structural parameters and also for the vibrational frequencies of melem according to temperature-dependent X-ray powder diffractometry investigations above 560 degrees C, melem transforms into a graphite-like C-N material.
Journal ArticleDOI
Tri-s-triazine derivatives. Part I. From trichloro-tri-s-triazine to graphitic C3N4 structures
Edwin Kroke,Marcus Schwarz,Elisabeth Horath-Bordon,Peter Kroll,Bruce C. Noll,Arlan D. Norman +5 more
TL;DR: In this paper, the first detailed structural characterisation of a functionalised tri-s-triazine derivative, trichloro-tri-s triazine, is reported, which is a promising starting material for numerous compounds including graphitic C3N4 phases.
Journal ArticleDOI
Synthesis of cubic silicon nitride
Andreas Zerr,Gerhard Miehe,George Serghiou,Marcus Schwarz,Edwin Kroke,Ralf Riedel,Hartmut Fueß,Peter Kroll,Reinhard Boehler +8 more
TL;DR: The hardness of the new phase, c-Si3N4, is comparable to that of the hardest known oxide (stishovite3, a high-pressure phase of SiO2), and significantly greater than the hardness of two hexagonal polymorphs as mentioned in this paper.
Journal ArticleDOI
High-pressure chemistry of nitride-based materials
Elisabeta Horvath-Bordon,Ralf Riedel,Andreas Zerr,Paul F. McMillan,Gudrun Auffermann,Yurii Prots,Welf Bronger,Rüdiger Kniep,Peter Kroll +8 more
TL;DR: The present critical review highlights recent developments that utilise high pressures and high-temperatures for the synthesis of new materials with unique properties, such as high hardness, or interesting magnetic or optoelectronic features.
Journal ArticleDOI
Hafnium nitride with thorium phosphide structure: physical properties and an assessment of the Hf-N, Zr-N, and Ti-N phase diagrams at high pressures and temperatures.
TL;DR: The calculated shear modulus G indicates that the cubic Hf3N4 will be harder than the mononitride HfN, and the orthorhombic phases of Hf2N4 and Zr3N 4 are stable with respect to the mon onitrides and nitrogen.
