Refractory materials, as key materials that withstand extreme environments such as high temperatures and corrosion, occupy an indispensable position in the entire energy industry chain. They are widely used in core areas such as fossil fuels, new energy, and energy conversion, providing core guarantees for the stability, efficiency, and safety of energy production.

In the fossil fuel sector, thermal power and coal chemical industry are the main application scenarios for refractory materials. In thermal power boilers, fuel combustion temperatures can reach over 1500℃. High-alumina and silica refractory bricks and castables are required in the furnace, flue, and other parts to resist the erosion of high-temperature flue gas and molten slag, extending the boiler’s service life and ensuring power generation efficiency. In coal chemical production, core equipment such as coal gasification furnaces and synthesis towers are subjected to high-temperature, high-pressure, and highly corrosive environments for extended periods. Linings constructed with corundum and silicon carbide refractory materials can effectively withstand the erosion caused by coal tar cracking and chemical reactions, ensuring the stable operation of the clean coal conversion process.
In the new energy sector, refractory materials are a crucial support for the photovoltaic, wind power, and energy storage industries. In photovoltaic silicon material production, reduction furnaces and distillation towers require refractory insulation materials that can withstand temperatures above 1200℃ to ensure the precision and efficiency of silicon material purification. The high-temperature curing process of wind turbine blade molding dies relies on refractory insulation materials to maintain a stable temperature field and improve blade forming quality. In the energy storage field, refractory materials provide high-temperature protection and corrosion resistance in the electrode sintering and electrolyte storage stages of sodium-ion batteries and vanadium redox flow batteries, ensuring the safe operation of energy storage equipment.
