Abstract
Provided are a method for preparing mullite porous ceramics using lithium slags and mullite porous ceramics and application thereof, relating to the technical field of resource reuse. The method for preparing mullite porous ceramics using lithium slags provided by the present invention includes the steps of: ball-milling lithium slags, alumina powder, and metal aluminum powder with water to obtain a slurry; stirring the slurry and a surfactant to obtain a wet foam; and drying the wet foam to obtain a dry foam, and sintering the dry foam to obtain the mullite porous ceramics. The mullite porous ceramics prepared according to the present invention have a very low shrinkage rate, which can reduce the post-processing costs of the porous ceramics and achieve high value-added recycling of lithium slags.
