Effect of mullite microcrystal on phase change mechanism of anorthite-based ceramics at low temperatures using electrolytic manganese residue.

Key Points

• This research examines how mullite microcrystals influence the phase change mechanisms of anorthite-based ceramics at low temperatures.
• Utilized electrolytic manganese residue as a sustainable raw material for synthesis.
• Investigated phase changes involving the formation of wollastonite and gehlenite.
• Identified spinel-like intermediates contributing to aluminum and silicon sources for anorthite.
• Demonstrated the potential for effective solid waste co-disposal in ceramic production.
