Cordierite mullite bricks have strong alkaline resistance, good chemical stability, high temperature resistance, and good resistance to rapid cooling and heating. They are water-cooled at 1000 ℃ for ≥ 100 times, making them a high-quality refractory brick
The thermal expansion coefficient of cordierite mullite brick is low, but its high temperature resistance is poor, while the thermal expansion coefficient of mullite material is large, but its high temperature resistance is good. During the high-temperature firing process, the two form micro crack structures, effectively preventing the generation and diffusion of thermal stress, and greatly improving the thermal shock resistance of the product
Cordierite mullite bricks are widely used in ceramic burners of hot air furnaces, kiln floor tiles, push plate tiles, sagger products, etc.
