Application

Molybdenum disilicide (MoSi2) is a ceramic material known for its exceptional high-temperature oxidation and corrosion resistance, making it ideal for several advanced applications. With a high melting temperature of 2200°C and impressive thermal durability, it serves as a substrate material for thermophotovoltaics and as a protective coating for carbon-carbon composites, particularly in aerospace and thermonuclear fusion. MoSi2's ability to withstand temperatures between 1200 and 1600°C opens up possibilities within these demanding environments. However, challenges exist due to its lack of ductility at temperatures up to 1000°C and reduced high-temperature strength caused by a silicon-rich grain boundary phase. These issues are being addressed through research, including the addition of carbon to enhance its properties. MoSi2's potential in high-stress, high-temperature applications makes it a valuable material in various advanced technologies.
