Abstract

We produced hexagonal ReB₂-type IrB₂ diboride and orthorhombic IrB monoboride phases, that were previously unknown and saw them produced by mechanochemical syntheses. High energy ball milling of elemental Ir and B powder for 30 h, followed by annealing of the powder at 1050 °C for 48 h, resulted in the formation of the desired phases. Both traditional laboratory and high resolution synchrotron X-ray diffraction (XRD) analyses were used for phase identification of the synthesized powder. Additionally, scanning electron microscopy and transmission electron microscopy were employed, along with XRD, to further characterize the microstructure of the phases produced.

In search of the elusive IrB{sub 2}: Can mechanochemistry help?

Journal Article Xie, Zhilin ; Blair, Richard G. ; Department of Physics, University of Central Florida, Orlando, FL 32816 ; ... - Journal of Solid State Chemistry

High temperature Ir segregation in Ir-B ceramics: Effect of oxygen presence on stability of IrB₂ and other Ir-B phases

Journal Article Xie, Zhilin ; Terracciano, Anthony C. ; Cullen, David A. ; ... - Advances in Applied Ceramics

The formation of IrB₂, IrB_1.35, IrB_1.1 and IrB monoboride phases in the Ir–B ceramic nanopowder was confirmed during mechanochemical reaction between metallic Ir and elemental B powders. The Ir–B phases were analysed after 90 h of high energy ball milling and after annealing of the powder for 72 h at 1050°C in vacuo. The iridium monoboride (IrB) orthorhombic phase was synthesised experimentally for the first time and identified by powder X-ray diffraction. Additionally, the ReB₂ type IrB₂ hexagonal phase was also produced for the first time and identified by high resolution transmission electron microscope.

Novel high pressure hexagonal OsB{sub 2} by mechanochemistry

Journal Article Xie, Zhilin ; Graule, Moritz ; Orlovskaya, Nina ; ... - Journal of Solid State Chemistry

Hexagonal OsB{sub 2}, a theoretically predicted high-pressure phase, has been synthesized for the first time by a mechanochemical method, i.e., high energy ball milling. X-ray diffraction indicated that formation of hexagonal OsB{sub 2} begins after 2.5 h of milling, and the reaction reaches equilibrium after 18 h of milling. Rietveld refinement of the powder data indicated that hexagonal OsB{sub 2} crystallizes in the P63/mmc space group (No. 194) with lattice parameters of a=2.916 Å and c=7.376 Å. Transmission electron microscopy confirmed the appearance of the hexagonal OsB{sub 2} phase after high energy ball milling. in situ X-ray diffraction experiments showedmore »« less

Thermal stability of hexagonal OsB{sub 2}

Journal Article Xie, Zhilin ; Blair, Richard G. ; Department of Physics, University of Central Florida, Orlando, FL 32816 ; ... - Journal of Solid State Chemistry

The synthesis of novel hexagonal ReB{sub 2}-type OsB{sub 2} ceramic powder was performed by high energy ball milling of elemental Os and B powders. Two different sources of B powder have been used for this mechanochemical synthesis. One B powder consisted of a mixture of amorphous and crystalline phases and a mixture of {sup 10}B and {sup 11}B isotopes with a fine particle size, while another B powder was a purely crystalline (rhombohedral) material consisting of enriched {sup 11}B isotope with coarse particle size. The same Os powder was used for the synthesis in both cases. It was established that,more »« less
