Composition Optimization of Lightweight High-Strength Mullite Castables – Performance Enhancement

With the implementation of the dual carbon strategy, high-temperature industries are facing increasingly stringent requirements for energy conservation and environmental protection, leading to an increase in the research and use of lightweight refractory materials. Mullite castables offer excellent properties such as a high refractoriness under load, good thermal shock resistance, and strong erosion resistance. They … Read more

Composition Optimization and Performance Enhancement of Lightweight High-Strength Mullite Castables

Lightweight and high-strength refractory materials, using microporous mullite, mullite fine powder, alumina powder, alumina hollow balls and silica powder as raw materials, and cement as binder, were prepared to prepare lightweight mullite castables. The effect of the amount of alumina hollow balls added (addition mass fraction was 0, 3%, 6% and 9% respectively) on the … Read more
