The Evolution of High-Temperature Application Demands: Mullite’s “Extreme Challenge”
As manufacturing technologies improve, the high-temperature environments that mullite refractories must withstand are becoming more complex. Particularly in fields such as metallurgy, aerospace, and new energy, the performance requirements for mullite are continuously increasing, driving innovations in material science.
1.1 Performance Requirements in Ultra-High-Temperature Environments
Modern industries require not only “heat resistance” from materials but also the ability to withstand extreme high-temperature conditions. In metallurgy, furnace linings, aerospace engine combustion chambers, and nuclear reactors all demand refractory materials that can withstand temperatures above 1600°C, maintaining mechanical strength and structural integrity over time. Therefore, mullite refractories must continue to improve their high-temperature strength, thermal expansion stability, oxidation resistance, and other properties to meet these “extreme” requirements.
1.2 Thermal Shock Resistance under Extreme Temperature Fluctuations
In many applications, mullite refractories must endure not just high temperatures but also extreme temperature fluctuations. For example, in smelting processes, furnace linings experience prolonged heating, followed by sudden cooling, making them highly susceptible to thermal shock cracking. Therefore, future research on mullite refractories must focus on improving their thermal shock resistance, enhancing their ability to withstand thermal cycling without cracking or breaking.
