Niobium Silicide Powder is a kind of powder composed of niobium and silicon, with hexagonal crystal structure, black-gray appearance, high purity, low density, high hardness, high melting point, good chemical stability, prepared by powder metallurgy, etc., which is widely used in the fields of high-temperature structural materials, electronic materials, ceramics materials, coating materials and so on.
Characteristics
Chemical formula and composition: The chemical formula is NbSi₂, which consists of the elements niobium (Nb) and silicon (Si).
Crystal structure: Hexagonal crystal structure, which gives it unique properties in physical and chemical properties and provides the basis for its application in different fields.
Appearance and Color: Usually a dark gray powder.
Density: With a density of approximately 5.7g/cm³, the relatively low density of Si₂ powder gives it an advantage in applications where weight is important.
Hardness: Vickers hardness between 5.88-6.88GPa, with high hardness, so that it is excellent in wear resistance, scratch resistance, etc., can be used in the preparation of parts that require high hardness and wear resistance.
Melting point: melting point up to 1950℃, with excellent high temperature stability, can maintain good performance in high temperature environment, so in the field of high-temperature structural materials has important application prospects.
Chemical stability: insoluble in water, concentrated hydrochloric acid, concentrated sulfuric acid, but soluble in a mixture of hydrofluoric acid and sulfuric acid, this special chemical stability makes it stable in some specific chemical environments, which broadens its scope of application.
Applications
High-temperature structural materials: Due to its high melting point, high-temperature stability and good mechanical properties, Niobium Silicide powder can be used in the preparation of high-temperature structural components in aerospace, energy and other fields, such as turbine blades, engine combustion chambers, etc., which can withstand high temperatures, high pressures and other harsh working conditions, and improve the service life and reliability of the components.
Electronic materials: In integrated circuits, Niobium Silicide powder can be used as diffusion barrier layer, contact materials, etc., can effectively prevent the diffusion of metal atoms, improve the performance and stability of electronic devices; in addition, it can still maintain good conductivity and stability at high temperatures, so that it has a potential application in high-temperature electronic devices.
Ceramic materials: When Niobium Silicide forms solid solution with zirconium disilicide, molybdenum disilicide, tungsten silicide, etc., it can be used as the raw material of fine ceramics for the preparation of high-performance ceramic materials such as ceramic cutting tools, ceramic bearings, etc., which have the advantages of high hardness, high abrasion resistance and high heat resistance.
Coating materials: Niobium Silicide Powder is made into coatings, which can be applied to metal surfaces to improve the oxidation resistance, abrasion resistance and corrosion resistance of metal materials and extend the service life of metal parts, and is widely used in the fields of machinery manufacturing, automobile industry and shipbuilding industry.
