Nickel Silicide Ni2Si powder is a powdered material made by melting and grinding nickel (Ni) and silicon (Si) in an atomic ratio of 2:1. The unique atomic combination of nickel and silicon gives it excellent physical and chemical properties, and it is mainly used in electronic materials, catalysis, metallurgy and other fields.
The powders supplied by VIMATERIAL are characterised by high purity, uniform particle size and good chemical stability. We can provide product customisation service according to customers’ requirements, while our products are packed in small packages, with small MOQs, sufficient product stock and short lead time. Our technical team has a lot of experience and can provide you with professional technical support, contact us.
Molecular formula: Ni2Si
Molecular weight: about 129.41
Appearance: Grey-black powder
Density: about 7.2 – 7.3g/cm³.
Melting point: about 1110°C
Crystal structure: Tetragonal crystal structure, this structure determines its unique performance in chemical reaction activity, electrical properties and other aspects.
Electronic material field: As a key additive for electronic pastes, Ni2Si powder can significantly improve the conductivity and adhesion of pastes. It is widely used in the connection of electrodes in chip manufacturing and the production of printed circuit boards, etc. It can improve the reliability of the connection between electronic components, reduce the resistance, and improve the operating efficiency of electronic equipment.
Metallurgy: In the preparation of special alloys, the addition of Ni2Si powder can effectively improve the strength, hardness and heat resistance of the alloy. For example, in the production of high-temperature alloys, the addition of Ni2Si powder can enhance the oxidation resistance and structural stability of alloys in high-temperature environments, so that they are suitable for the manufacture of high-temperature parts of aircraft engines and heat-resistant components of industrial furnaces.
Catalyst field: Ni2Si powder has certain catalytic activity, and can be used as catalyst or catalyst carrier in some organic synthesis reactions. For example, in hydrogenation reaction, dehydrogenation reaction and other processes, it can reduce the activation energy of the reaction, improve the reaction rate and selectivity, which can help the chemical production process to be carried out efficiently and reduce the production cost.
The production process of each batch of powder strictly follows the international advanced quality control system. Strict inspections are carried out at every stage, from raw materials, production to finished product inspection. The inspection includes X-ray diffraction (XRD), scanning electron microscope (SEM), laser particle size analysis, powder composition, physical properties (such as bulk density, vibration density, etc.), chemical composition and microstructure.
Nickel Silicide Ni2Si powder are vacuum-packed in bottles, foam-filled, in customised cartons.
Nickel Silicide Ni2Si powder is vacuum packed and placed in a dry, ventilated environment, avoiding direct sunlight, and the temperature should be kept low and stable.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
