Uses

Used in Superconducting Applications:
Lanthanum Nickel is used as a superconducting material for its ability to conduct electricity with zero resistance when cooled below a specific temperature. This property makes it highly suitable for applications that require efficient energy transfer and minimal energy loss.
Used in Lanthanum Nickel Boro-Nitride:
Lanthanum Nickel is used as a superconducting intermetallic phase in Lanthanum Nickel Boro-Nitride. LANTHANUM NICKEL is a type of superconductor that can carry large amounts of electrical current without resistance, making it ideal for applications that require high-performance electrical conduction, such as power transmission lines, magnetic levitation trains, and advanced medical imaging equipment.

Electrical and thermal transport in CeNi and LaNi

We have measured the electrical resistivity and thermal conductivity of CeNi, LaNi and La 0.15Ce 0.85Ni in the temperature range 4-400 K simultaneously on the same specimen using the TTO option in PPMS (Quantum Design) facility. Anom

Effect of sintering conditions on the formation of single-phase NdMgNi4 compound and its hydrogen storage properties

Effects of different sintering conditions on the formation of single-phase NdMgNi4 compound and its electrochemical properties have been investigated. XRD analysis shows that an ideal single-phase compound of NdMgNi4 can be synthesized by sintering the pressed tablets of mixture of Mg, Ni and NdNi powders under 973 K for 5 h; single-phase compounds of REMgNi4 (RE = La, Ce, Pr) can be synthesized in this way as well. The electrochemical properties were measured by simulated battery tests. The maximum discharge capacity of NdMgNi4 compound was about 200 mAh/g, and just 78 mAh/g for CeMgNi4 compound. NdMgNi4 compound could store 3.5 H/M of hydrogen under 2.5 MPa at 298 K, whilst it is difficult to absorb hydrogen at a higher temperature (473 K).

Effect of chemical and external pressure on the structure of intermetallic compound CeNi

Neutron powder diffraction was employed to study the structural modifications of the intermediate-valence compound CeNi at room temperature induced by either chemical or external pressure. For the first time we were able to record the diffraction pattern resulting from the pressure-induced first-order phase transition occurring in CeNi at 300 K. At pressure P = 2 GPa we observe the coexistence of two phases while only single pressure-induced phase is visible at P = 5 GPa. The results obtained are indicative of a higher symmetry of the collapsed structure as compared to the CrB-type ambient pressure structure of CeNi. The critical pressure range around 2 GPa is found to be agreement with the previous estimation derived from the thermopower measurements.

The isothermal section of the phase diagram of the La-Ni-Cu ternary system at 673 K

The isothermal section of the phase diagram of the ternary system La-Ni-Cu has been investigated by X-ray diffraction, differential thermal analysis, optical microscopy and electron microscopy techniques. It consists of 13 single-phase regions, 23 two-phase regions and 11 three-phase regions. At 673 K, the maximum solid solubility of Cu in La2Ni3, La 2Ni3, La2Ni3, LaNi is and LaNi is about 2, 2, 3, 3 and 5 at.% Cu, respectively. The solid solubility of Cu in La7Ni3 and Ni in LaCu6 is too small to observe. Cu and Ni can replace each other in LaNi5 and LaCu5, the LaNi5 and LaCu5 form a continuous solid solution. The maximum solid solubility of Ni in LaCu2 and LaCu is about 15 and 4at.% Ni, respectively. A new ternary compound La10Cu 85Ni5 has been observed in the La-Ni-Cu ternary system.

The 673 K isothermal section of the La-Ni-Sn ternary system

The phase relationships in the La-Ni-Sn ternary system at 673 K have been investigated by means of X-ray powder diffraction (XRD), differential thermal analysis (DTA), scanning electron microscopy (SEM) and electron probe microanalysis (EPMA). Most of this ternary system was studied at 673 K. At this temperature, a new ternary compound whose atomic ratio is close to La/Ni/Sn = 1:1:3 has been found. The existences of 15 binary compounds La 7Ni3, LaNi, La2Ni3, La 7Ni16, LaNi3, La2Ni7, LaNi5, Ni3Sn, Ni3Sn2, Ni 3Sn4, La5Sn3, La5Sn 4, LaSn, La3Sn5, LaSn3 and seven other ternary compounds LaNi5Sn, LaNi4Sn2, LaNi2Sn2, La3Ni2Sn6, La3Ni2Sn7, La3Ni8Sn 16, LaNiSn have been confirmed too. There are 31 three-phase regions in the 673 K isothermal section. Due to the lower melting point of Sn (about 504 K), a small part of the ternary system that lies in the Sn-rich part was studied at 483 K.

Amorphous La-Ni thin film electrodes

Amorphous La-Ni thin films over a wide range of composition were fabricated by electron beam evaporation in ultra-high vacuum. The structure and composition of these films were determined by X-ray diffraction (XRD), transmission electron microscopy (TEM) and electron probe microanalysis (EPMA). The reversible hydrogen storage capacity was determined by electrochemical cycling. The equilibrium electrochemical potential of these thin-film electrodes was also measured versus the change of hydrogen concentration, ΔH/M, in these films. The smallest value among the maximum ΔH/M of these amorphous films is about 0.38, which is still much larger than the one reported in the literature (approx.0.1). Harris's model for hydrogen absorption in amorphous transition metal alloys is applied to the amorphous La-Ni system. We found that both the La-Ni3 and the La2-Ni2 type of tetrahedral sites can store hydrogen.
