Molybdenum Silicide powders are intermetallic powders consisting of molybdenum and silicon with high melting points, high hardness, good oxidation resistance and electrical conductivity.
Properties
Appearance: Grey crystalline powder with metallic lustre.
Density: about 6.26-6.31g/cm³.
Melting point: 1930°C-2030°C.
Solubility: Insoluble in most acids, but soluble in hydrofluoric acid and nitric acid.
Specific surface area: nanoscale molybdenum disilicide powder has a large specific surface area.
Thermal stability: Molybdenum Silicide has excellent high-temperature antioxidant property, at high temperature the surface can form a silica passivation layer, preventing further oxidation, and it can be stable for a long time under high temperature environment.
Mechanical properties: high strength and high modulus of elasticity.
Electrical properties: Molybdenum Silicide has good electrical conductivity, its resistivity in a certain temperature range is relatively stable, can be used as electrical heating elements and integrated circuits in the conductive materials.
Thermal properties: a low coefficient of thermal expansion, in the temperature change, the shape and size of the change is small, is conducive to maintaining the stability and reliability of the material.
Applications

Electric heating element: the use of its good conductivity and high temperature stability, made of heating rods, etc., used in high-temperature furnaces and kilns, laboratory heating equipment, etc., can be stable at high temperatures heat.
Heat exchanger: excellent thermal conductivity and high-temperature oxidation resistance makes it suitable for use in atomic reactors and other heat exchangers, can efficiently transfer heat.
Electronic field
Integrated circuits: as a candidate material for large-scale integrated circuit gate and interconnect wire films, it meets the requirements of high integration and high performance, and helps to improve the operating speed and reliability of integrated circuits.
Aerospace
Antioxidant Coating: Molybdenum Silicide can form a dense oxidative protective film on the surface of blades, impellers, combustors and other components of turbine engines, preventing the diffusion of oxygen, improving the antioxidant performance of the components, and prolonging their service life.
Automotive field
Engine components: such as turbocharger rotor, valve body, spark plugs, etc. Its excellent performance can ensure that the engine components in high temperature, high pressure and other harsh conditions of stable work, improve engine performance and efficiency.
Other aspects
Composite material reinforcement: added to ceramics, metals and other matrix materials to improve the strength, hardness, wear resistance and high temperature stability of composite materials.
Wear-resistant materials: Molybdenum Silicide is used to manufacture wear-resistant parts such as cutting tools, moulds, bearings, etc. to prolong service life.
Ceramic connecting material: as the connecting material of structural ceramics, it can connect ceramic parts into complex structural parts to meet different engineering needs.
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.
