A comparative study on combustion synthesis of Ta–B compounds

Prediction of new high pressure phase of TaB3: First-principles

“…Among them, tantalum borides are a group of materials with outstanding properties such as chemical inertness, high hardness, wear resistance, good thermal and electrical conductivity. Therefore, diverse experimental and theoretical investigations have been carried out for tantalum borides [14][15][16][17][18][19][20][21][22][23][24][25]. Experimentally, Ta 2 B was the first reported tantalum boride with tetragonal Al 2 Cu-type structure (I4/mcm, a=5.783Å, c=4.866Å) [18], while the stoichiometry of Ta 2 B could not be determined accurately at that time.…”

An investigation on the formation mechanism of nano CrB2 powder in the Mg–B2O3–Cr2O3 system

“…Formation of a variety of transition metal diborides MB 2 (M = Nb, Mo, Ta, Ti, Hf, V, and Cr) have been conducted by combustion synthesis from constituent elements in the mode of self-propagation of high temperature (SHS) [9][10][11][12][13]. However, when direct combustion between the metal and boron is not feasible due largely to insufficient exothermicity, the SHS process involving borothermic and boron carbide reductions of chromium oxide has been considered as an alternative for preparing the chromium borides [6][7][8].…”

Preparation of tungsten borides by combustion synthesis involving borothermic reduction of WO3

“…Formation of a variety of transition metal borides, including the Ti-B, Zr-B, Hf-B, V-B, Nb-B, and Ta-B compounds, has been conducted by combustion synthesis of constituent elements in the mode of self-propagating high-temperature synthesis (SHS) [3][4][5][6][7][8][9]. The SHS process takes advantage of the self-sustaining merit from highly exothermic reactions and hence has the potential of time and energy savings [10][11][12][13].…”
