High-temperature materials are specially designed substances that can withstand extreme temperatures without losing their structural integrity or performance. These materials are essential in various industries, including aerospace, automotive, and energy, where they are used in applications like jet engines, nuclear reactors, and gas turbines. Common types of high-temperature materials include ceramics, superalloys, and refractory metals. These materials often exhibit properties such as high melting points, excellent thermal stability, and resistance to oxidation and corrosion, making them suitable for environments that exceed standard operating temperatures.
