Synthesis of 3:2 mullite ceramics from silica-enriched filter cake waste via diphasic gels method [PDF]
Mullite ceramics were synthesized from filter cake waste following the diphasic gel method. Filter cake waste, with over 65% silica content, and aluminum nitrate nonahydrate were utilized as the sources of silica and alumina, respectively.

Study on the Effect of Binders on the Properties of Mullite Porous Ceramics for Flue Gas Filtration [PDF]
Fused mullite particles are used to prepare mullite porous ceramics by gel-casting method, using polysilicon waste and ρ-Al2O3 powder as the binder, and starch as the pore forming agent. The content of the pore forming agent was 20%, and the ratio of the

Thermal insulating properties of hollow mullite fibers prepared on a ceiba bio-template
Ceiba fibers have excellent thermal insulating properties because of their hollow structures. Mullite fibers are widely used in heat-insulating refractory materials because of their low thermal conductivity and excellent thermal shock stability. However,
