Molybdenum disilicide (MoSi2) heating elements are renowned for their high-temperature resistance, corrosion resistance, and long service life, making them ideal for various industrial applications. These elements operate effectively in oxidizing atmospheres due to a protective SiO2 glass film that forms on their surface. The temperature range for MoSi2 heating elements typically spans from 500°C to 1800°C, depending on the specific type and environmental conditions. The 1700-type components are designed for use up to 1700°C, while the 1800-type can withstand temperatures up to 1800°C. These elements are particularly valued for their durability and performance in high-temperature environments.
