Lanthanum Nickel Alloy

Lanthanum Nickel Alloy particles are a kind of alloy particles mainly composed of lanthanum and nickel, silver grey in colour, with high chemical activity, good hydrogen absorption properties, and to a certain extent, improve the physical and chemical properties of nickel, and play an important role in a number of fields, such as hydrogen storage materials, battery electrodes, catalysts, and so on.

Characteristic

Colour: Lanthanum Nickel Alloy particles usually have a silvery grey metallic colour.

Melting point: It has a relatively low melting point of around 480°C, which allows it to be processed and handled at lower temperatures.

Density: Relatively high density, around 7.950g/cm³, which gives it an advantage in applications where weight and volume are important.

Hardness: Generally high hardness, able to withstand a certain degree of mechanical stress and wear, which is important for its stability and durability in a variety of applications.

Crystal Structure Properties: Lanthanum Nickel Alloy has a specific crystal structure, such as the common Calcium-Copper-Copper V (CaCu₅)-type crystal structure, which gives the material its unique physical and chemical properties.

Poor resistance to oxidation: oxidation reaction occurs easily in air, and the surface is prone to blackening, which is due to the fact that the elements lanthanum and nickel tend to form oxides when they come into contact with oxygen in air.

Hydrogen storage properties: it has good adsorption and storage capacity for hydrogen, and can absorb a large amount of hydrogen under certain conditions and release it under specific conditions, which makes it has important application value in the field of hydrogen storage.

Good 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 chemical reactions such as the synthesis of multi-walled carbon nanotubes by chemical vapour deposition.

Applications

Hydrogen storage material: It is an important hydrogen storage material, which can be used for the storage and transport of hydrogen. For example, in fuel cell vehicles, Lanthanum Nickel Alloy particles can be used as a key material in hydrogen storage tanks to store and release hydrogen to power the vehicle.

Battery Electrode Material: It has application potential in the field of new batteries, and can be used as electrode material for batteries such as nickel-metal hydride batteries. Its good hydrogen storage performance and electrochemical activity can improve the charging and discharging performance and cycle life of the battery.

Catalyst: It can be used to catalyse a variety of chemical reactions, such as the synthesis of multi-walled carbon nanotubes by chemical vapour deposition. In the field of chemical industry, as a catalyst can accelerate the chemical reaction, improve the efficiency and selectivity of the reaction, and reduce the temperature and pressure and other conditions of the reaction.

Other applications: In the preparation of some special alloy materials, Lanthanum Nickel Alloy particles can be used as an additive element to improve the properties of the alloy. For example, in some high-temperature alloys or corrosion-resistant alloys, the addition of an appropriate amount of Lanthanum Nickel Alloy particles can improve the alloy’s strength, corrosion resistance and high-temperature resistance.
