Recent studies of mullite formation in clays and clay-based vitreous ceramic systems are
reviewed. In such systems, mullite crystals grow in a viscous aluminosilicate liquid, as …

Nanoscience and nanotechnology applications have shown remarkable progress in several
industrial fields, producing advance materials. Nowadays, there are a great number of …

Nearly half of the total iron ore volume extracted in mining operations is rejected as tailings
and disposed of in containment dams that are liable for considerable environmental impact …

Various forms of mullite occur in porcelains. Primary mullite forms from decomposition of
pure clay. Secondary mullite forms from reaction of feldspar and clay and feldpar, clay and …

Microstructural evolution on heating was investigated in a reference industrial composition
(50% kaolinitic clay, 40% feldspar and 10% quartz) of porcelain stoneware, fast fired at …

Quartz was progressively replaced by 5, 10 and 15 wt.% fly ash (a byproduct of Indian
thermal power plant) in a traditional triaxial porcelain composition consisting of kaolinitic …

Thermal transformation of illite and smectite group clay minerals was studied using X‐ray
diffraction and transmission electron microscopy, and the results were compared with those …

Porcelain stoneware is a strongly sintered ceramic material fabricated from ball clays-quartz-
feldspar mixtures. Porcelain stoneware is characterized by its excellent technical and …

Building ceramics are gained by firing natural clays which contains various materials. The
main and the most used mineral is kaolin. Kaolin is a soft, lightweight, often chalk-like …

Steel slag, an industrial waste discharged from steelmaking process, cannot be extensively
used in traditional aluminosilicate based ceramics manufacturing for its high content of …
