Thermodynamic Computation and analysis were carried out both TiO 2 -C-Ar and TiO 2 -C-N 2 systems using the Factsage thermodynamic software. The results show that TiO 2 was deoxidated step by step as follows: TiO 2 ĺ7L 20 O 39 ĺ7L 10 O 19 ĺ7L n O 2n-1 ĺ7L 3 O 5 ĺ7L17L&. TiC come into being at 1343.2 and 4.8wt%C. TiC coexists with C up to 31.2wt% in TiO 2 -C-Ar systems. TiN come into being at 1148.9 and 4.8wt%C in TiO 2 -C-N 2 systems. The solid solution Ti (C, N) formed with TiN and TiC at 1566.8 and C is within 23.1wt% < C < 31.2wt%. TiN die away when C > 31.2wt%. The stationary phase are TiC coexistence with residual C at high temperature and C enough zone. The simulated computaion methods are feasibly verified by the XRD detected phase composition for the actual blast furnace slag using schreyerite ironmaking.

“…With milled samples, exothermic peaks might have occurred due to the oxidation of graphite and due to the formation of TiC [15,16]. Endothermic peaks might be due to the transformation to lower oxides of Ti [17]. Lower oxides of Ti are indicated in Fig.…”

“…Wan et al synthetized four phases of molybdenum carbide (α-MoC1−x, β-Mo2C, η-MoC, and γ-MoC), studied and compared the catalytic performances for multiple phases of molybdenum carbide [20,21]. The main synthetic methods of TMCs are as below: the direct carbonization of transition metal oxides [22], chemical vapor deposition (CVD) [23], the self-propagating high-temperature synthesis (SHS) [24], and microwave treatment [25]. Additionally, high-pressure, high-temperature (HPHT) is an effective way to prepare TMCs.…”

For the first time, the hydrogen evolution reaction (HER) electrocatalytic performances of incompressible γ-Mo 0.5 W 0.5 C, prepared by high-pressure, high-temperature (HPHT) synthesis, were investigated in the electrolyte. The polarization curve of the γ-Mo 0.5 W 0.5 C cathode exhibits the current density of 50 mA·cm −2 at an overpotential value of 320 mV. The corresponding Tafel slope of the incompressible γ-Mo 0.5 W 0.5 C is 74 mV·dec −1 . After a 1000-cycle test, and then exposure to the air for six months, the γ-Mo 0.5 W 0.5 C electrode performed a current density of 50 mA·cm −2 at an overpotential of 354 mV, which was close to the initial one.
