Lanthanum Nickel Alloy Powder is an alloy powder composed of lanthanum and nickel, silver grey in colour, with fine particles, large specific surface area, high chemical activity, good hydrogen storage performance, and plays a key role in many fields, such as hydrogen storage materials, batteries and catalysis.
Characteristics
Molecular weight: for LaNi₅, the common lanthanide-nickel alloy phase, the theoretical molecular weight is 432.37; for other proportions of La and Ni, the molecular weight will vary
Density: approx. 7.950 g/cm³.
Melting point: approx. 480 °C.
Appearance: Usually appears as a silvery grey powder.
Particle size: The particle size of the powder can be adjusted according to the demand, ranging from submicron to micron, smaller particle size can increase the specific surface area of the material, improve its reactivity and adsorption performance.
Poor oxidation resistance: both lanthanum and nickel elements are easily oxidised in air, and lanthanum-nickel alloy powders are no exception. In the air, its surface easily reacts with oxygen to generate oxides, reducing the performance of the material.
Hydrogen storage properties: it has good adsorption and storage capacity for hydrogen, can absorb a large amount of hydrogen under certain conditions and release hydrogen under specific conditions, and is one of the more widely used hydrogen storage materials.
Catalytic properties: Due to its special electronic structure and surface properties, it has a good catalytic effect on certain chemical reactions, for example, it can be used as a catalyst for hydrogenation reaction.
APPLICATIONS
Hydrogen storage: Lanthanum Nickel Alloy is an important hydrogen storage material, which can be used for hydrogen storage and transport. For example, in fuel cell vehicles, lanthanum-nickel alloy powder can be used as a key material for hydrogen storage tanks, storing and releasing hydrogen to power the vehicle.
Battery field: Lanthanum Nickel Alloy can be used to prepare electrode materials for batteries such as nickel-metal hydride batteries, etc. Its good hydrogen storage performance and electrochemical activity can improve the charging and discharging performance and cycle life of the battery.
Catalysis: Lanthanum Nickel Alloy powders are widely used as catalysts in a variety of chemical reactions, such as the synthesis of multi-walled carbon nanotubes by chemical vapour deposition, which can accelerate the progress of the chemical reaction and improve the efficiency and selectivity of the reaction.
Alloy material preparation: Lanthanum Nickel Alloy Powder can be used as an additive element in the preparation of some special alloy materials to improve the performance of the alloy, such as improving the alloy’s strength, corrosion resistance and high temperature resistance.
Other fields: it can be used in the preparation of metal coatings and anticorrosion coatings to improve the service life of coatings; in ceramic materials, the addition of lanthanum-nickel alloy powder can improve the electrical conductivity and thermal conductivity of ceramics, and improve the temperature resistance and wear resistance of ceramics.
