Molybdenum, a refractory metal is widely used as an alloying element. Due to its good thermal and electrical conductivity, high melting point and excellent strength at elevated temperatures, molybdenum can be used for various applications in its pure form. In addition, molybdenum has low thermal expansion coefficient.
The most important material within the semiconductor industry is Silicon. When dealing with electro-thermal device modelling, or the interpretation of fast transient techniques for the measurement of thermal impedance, thermal conductivity of Silicon is required.
Silicon carbide (SiC) products are ideal for applications where improvements in efficiency, reliability, and thermal management are desired. Silicon Carbide also has the resistivity necessary to perform as a semiconductor material. Because of these properties, Silicon Carbide is used in a wide range of applications and industries.
High power densities and the flow of electricity through power diodes and transistors generate heat. Thanks to its good thermal conductivity and thermal expansion properties that are adapted to the relevant semiconductor material, molybdenum and its alloys are the perfect substrate for power electronics.
The thermal and electrical conductivities of silicon have been investigated in solid and liquid states. It is shown that in solid state region at temperatures close to melting point phonon and electron mechanisms including the ambipolar part are dominant in thermal conductivity. The electronic contribution including the ambipolar
Molybdenum provides corrosion resistance that is similar to tungsten. Molybdenum particularly resists non-oxidizing mineral acids. It is relatively inert to carbon dioxide, ammonia, and nitrogen to 1100°C and also in reducing atmospheres containing hydrogen sulfide.
J D Global Trading Company is Molybdenum series (molybdenum powder, high pure molybdenum trioxide, molybdenum bar, molybdenum stretch, molybdenum sheet, molybdenum plate, molybdenum rod, molybdenum special type parts, etc); Molybdenum electrode and the serial products of water-cool jacket (molybdenum rod electrode, molybdenum plate electrode) supplier and exporter.
Molybdenum-based alloys have a unique combination of properties, including high strength at elevated temperatures, high thermal and electrical conductivity, and low thermal expansion. Molybdenum metal and its alloys are the first choice in many demanding specialized applications.
of MoW alloys is lower than 100 W/mK for all temperatures investigated and much smaller as compared to pure molybdenum and tungsten. In addition, the conductivities of Mo and W decrease with increasing temperature while the conductivity of the MoW alloy indicates increasing values with increasing temperature.
